A Report On The Digestive System
Andres Nogales
Professor Dr. Felton
Essay 1: Since this student had a bag of chips which is carbs and turkey sandwich which is
considered protein and fat and water. The first stage in the digestive system is ingestion when the
student enters his lunch in their mouth. In this stage there is mechanical and chemical digestion
taken place. The mechanical digestion is take place by biting and tearing the food into smaller parts
which would then be known as bolus. Chemical digestion is occurred when the three salivary glands
sublingual, submandibular, and paratoid gland that secretes saliva which contains amylase. Amylase
is used in this case to breakdown starch. In the mouth the carbohydrates and fat are broken down. In
carbohydrates the starch and disaccharides are mixed with the salivary amylase, and in fats the
unemulsified triglycerides are mixed with lingual lipase. Once mechanical and chemical digestion is
complete in the mouth food continues its route to the digestive system going through deglutition. In
deglutition the esophagus sphincter begins to contract in which the tongue forces the bolus upward
towards the hard palate making the bolus to enter the oropharynx. Once it enter the oropharynx in
order to prevent the bolus to enter the trachea the uvula and larynx rise upward and the superior
esophageal sphincter starts to relax which would then allow food to enter the esophagus. Once that
occurs the muscles of pharynx contract making the bolus to travel down the

Digestive System Of The Digestive System
Digestive System After dissecting the rat, we learned that the rat's body has many complex systems.
To begin, the digestive system contains a group of organs that work together to convert food taken in
from the body and converts it to energy and basic nutrients to feed the cells in the body. The
digestive system includes the mouth, pyloric valve or sphincter, caecum, small intestine, colon
(large intestine), duodenum, retrum, and stomach. The salivary glands, liver, and pancreas are glands
that are laid outside of the digestive system, but they are associated with contributing to the system's
function. The mouth processes the food so that it is easier to swallow. From the mouth, it moves to
the back of the mouth.
Pharynx
The pharynx is where the food moves into from the back of the mouth. It is separated into three
pathways. The nasopharynx is a pathway for only air, the oropharynx is a pathway for food and air,
and the laryngopharynx is where both food and air pass by penetrating through the nose.
Esophagus
After successfully passing through the pharynx, it moves to the esophagus. The esophagus links
together the stomach and the pharynx so when food is consumed by the organism, it moves into the
stomach.
Stomach
The stomach muscles work together to break down food so part of digestion takes place here. It also
produces acids (hydrochloric acid) and enzymes (pepsin) and mucus which work together to break
down proteins. The stomach also functions to portion food into

the proper functioning and structure of our body. Digestive system ensures that these nutrients are
made available for the body. These nutrients are derived from the food we eat. Food comes from
water, organic molecules such as fats, carbohydrates, proteins, vitamins etc, and inorganic salts.
Food provides fuel to the body in the form of calories which are required by the body to carry out
daily activities. These calories mainly come from carbohydrates and fats. Proteins support the growth
and repair functions of the body. Inorganic salts are important to keep running many of the body
processes e.g. sodium, potassium, and chloride act as electrolytes and maintain fluid balance and
normal blood pressure. The digestive system consists of a group of organs which help in the
ingestion, breakdown, digestion, absorption, and egestion (excretion) of the food. These organs
make up the Digestive Tract and the Accessory Structures that lie outside the tract but are connected
to it through tubes or ducts. The Digestive

They can produce cellulose enzyme, which cannot be produce by cow's digestion. They help to
break down cellulose into glucose. When cow have a break, they regurgitate or "cud" food from
their stomach back to their mouth to chew again and mixing with saliva. At that time, food partly
broken down by bacteria, mixed with bacteria and chewing again makes the cow gain nutrient from
the food maximally. After chewing again, the food and bacteria will pass to abomasum (the true
stomach). The food will be broken down into nutrients and the cow can gain amount of protein from
digesting bacteria.

Digestive System
The Digestive system:
The stomach related framework is comprised of the gastrointestinal (GI) tract–likewise called the
stomach related tract–and the liver, pancreas, and gallbladder. The GI tract is a progression of empty
organs participated in a long, bending tube from the mouth to the butt. The empty organs that make
up the GI tract are the mouth, throat, stomach, small digestive system, internal organ–which
incorporates the rectum–and butt. Sustenance enters the mouth and goes to the rear–end through the
empty organs of the GI tract. The liver, pancreas, and gallbladder are the strong organs of the
stomach related framework. The stomach related framework enables the body to process
nourishment.
Why is digestion important?
Digestion is critical for separating nourishment into supplements, which the body utilizes for vitality,
development, and cell repair. Sustenance and drink must be changed into littler particles of
supplements before the blood retains them and conveys them to cells all through the body. The body
separates supplements from sustenance and drink into starches, protein, fats, and vitamins....show

Processing works by moving nourishment through the GI tract. Assimilation starts in the mouth with
biting and finishes in the small digestive system. As sustenance goes through the GI tract, it blends
with stomach related juices, making substantial particles of nourishment separate into littler atoms.
The body at that point ingests these littler particles through the dividers of the small digestive system
into the circulatory system, which conveys them to whatever remains of the body. Squander results
of assimilation go through the internal organ and out of the body as a strong issue called

Explain The Structure Of The Digestive System
The structure of the digestive system consists of organs that help break down food, absorb nutrients,
and eliminate wastes. Organs that contribute to the breakdown of food include the mouth,
esophagus, and stomach as well as the pancreas and gallbladder. Nutrients are absorbed through the
small intestine, and remaining waste is eliminated through the large intestine and

The Digestive System Why is it that 1 in 3 people perhaps even more regularly battles some kind
of digestion problems? Understanding how the digestive system works will help to understand why
digestive problems are so common. The digestive system is more than stomach and intestines. It is
a system of organs that turns food into energy and is one of the most important functions the body
performs. There are many reasons that cause so many people to suffer with digestive problems.
Three of the most common reasons are the lack of knowledge of how the digestive system works,

The large intestine is to remove water and salts from the undigested material and to form solid
waste that can be excreted. Bacteria in the large intestine help to break down the undigested
materials. The remaining contents of the large intestine are moved toward the rectum where feces
are stored until they leave the body through the anus. The anus is the last part of the digestive tract.
Accessory digestive organs which include the pancreas, liver and gall bladder are not part of the
digestive tract or also known as the alimentary canal, but play an important role in the digestive
process. The pancreas produces enzymes that help digest proteins, fats and carbohydrates it also
makes sodium bicarbonate which neutralizes stomach acid. The liver produces bile, which helps the
body absorb fat and it also regulates substances in the blood cells. The gallbladder stores bile until it
is needed. The enzymes and bile produced by these organs move through ducts into the small
intestine where they help breakdown food. The nutrients from the small intestine travel through the
blood to the liver, which help process the nutrients. Digestive problems results from poor nutrition.
Good nutrition is essential for maintaining proper functioning of the body systems especially the
digestive system. Eating a well–balanced, nutritious diet and maintaining a healthy lifestyle are the
best ways to prevent digestive problems and diseases (Lipski, 2005). The kinds and

Digestive Systems And The Digestive System
Abstract
The digestive system provides for the function of the human body to take in consumptions, ingest
those consumptions, break down complex molecules that make up those consumptions, absorb the
necessary components our bodies need to function, and proceed to remove the waste product. This
process is performed through means of complex mechanic and chemical digestion, and uses several
major organs and components of the body to perform these processes. Additional functions are
performed by hormones and enzymes secreted through various parts of the digestive organs as well.
As a result of these functionals, the body is enabled to maintain homeostasis, and live ultimately
healthier lives. However, health risks from various forms of problems and disorders within the
digestive system can be altered significant amounts from consuming foods and substances that will
have a negative affect on our bodies. Fortunately, we have the ability to pick and choose what goes
into our digestive tract, and what does not.
The Digestive System As living and breathing human beings, we have all sorts of necessities that
need to be fulfilled in order to maintain our health, chemical balance, and survival. Many of these
necessities account for the various bodily parts and functionals that reside within us. The body
consists of eleven organ systems which all perform specific functions that allow us to fulfill,
maintain, and monitor these necessities through out our life span.

Digestive system and Urinary System
The digestive system is a group of organs working together to convert food into energy. The food
digested is also tied into basic nutrients to feed the body. The digestive system is something called
the tube within a tube. This is because it is a hollow structure with two openings that run the height
of your body. The digestive tract consists of two parts the gastrointestinal tract known as GI tract
and a set of accessory organs. GI tract starting at the oral cavity, through abdominal cavity and end at
the anus. Major accessory organs include pancreas, liver, and gallbladder. There are 5 basic processes
the digestive system have. The processes include and ingestion, mixing digestion, absorption, and
defecation. Ingestion is the first step which is when the food and liquids are taken in the mouth and
eaten. Mixing is when the smooth muscles in the walls of the GI tract mixes the food and send it
through the tract. Next is digestion where the food is broken down by mechanical and chemical
processes. Absorption is the epithelial...show more content...
It is composed of four layers: The innermost layer is composed of a mucous membrane, or mucosa .
This slippery, smooth layer allows ingested food to move along the tract without tearing it. оЂЂ
Under the mucosa, the submucosa includes the glands, nerves, and blood supply for the tract itself.
The muscularis gives the tract the ability to move substances lengthwise. For most of the tract, the
muscula–ris is composed of one layer of longitudinal muscle above another layer of circular muscle.
The outer layer of the GI tract, the serosa , is a slippery membrane that permits the tract to move
inside the abdom–inal cavity without catching or causing discomfort. Your digestive system is
always active, as muscular contractions shift, lengthen, and shorten the tube. Although this
move–ment is constant, you normally neither see nor feel

Digestive System Lab Report
The purpose of this lab was to see how the digestive system length of my body compares with a
rabbit, dog and koala. This is a dilemma to find out without prior knowledge because of the small
sizes of the animals and our large size in comparison.
My data shows the lengths of these animals and my own digestive system. I found my own digestive
system length by measuring the body parts that are associated with the digestive system. The
measurements began at the mouth, where the digestion process begins. It is where the food gets
crushed up into smaller pieces for easier swallowing. In centimeters, we measured the length of our
mouth from the jawline to the front of the mouth giving us 13.5 cm. Next we measured the next
body part in the digestion system the esophagus. We...show more content...
The esophagus is what connects the mouth to the stomach which will be the next thing we will be
measuring. The stomach was measured by using the measuring the tip of our picky to the tip if the
thumb, making it 17.0 cm. To find the stomach length we multiplied our height by 4 which gave
me 630.8 cm because my height is 157.7 cm. The long intestine is simply your height which means
my long intestine is 157.7 cm. If you total all of these measurements up it equates to 840.2 cm
making this the size of my whole digestive system. The next step in the lab was to measure the
other animal's digestive system. We did this by using yarn on a piece of paper that had a picture of
the other animals systems in it. For all of the animals we traced the system with a piece of yarn then
measuring it. We measured the system using centimeters and excluding the length of the caecum. So
we just measured the length of the stomach, small intestine and the large intestine and later on added
the length of the caecum with it. When I measured the rabbit, the measurement of the major parts of
the system was 63.0 cm and the caecum was 9.7 cm. We added that together making it equal 72.7
cm. I multiplied it

The Digestive System Of Digestion Essay
Digestion is the breaking apart of foods into smaller and smaller units and absorbtion is the
movements of those small units from the gut into the bloodstream or lymphatic system for
circulation. (1) The digestive system is what keeps you going from day to day because without the
digestive system you wouldn't be able to consume anything. You also wouldn't be able to absorb the
necessary nutrients you need for your body to keep functioning correctly. The organs that play a role
in the digestive system is the mouth, esophagus, stomach, small intestine, large intestine, appendix,
rectum, liver, gallbladder, pancreas, and the anal canal. The mouth is where it all starts. Before you
even take a bite of your food, the smell of the food is what triggers your salivary glands which
include the parotid, sublingual, and submandibular glands in your mouth making it start to water.
Your saliva increases when you taste the food. When you chew the food into smaller pieces the
enzyme amylase breaks food into small sugar molecules. To start fatdigestion another enzyme is
released at the base of the tongue called lingual lipase. A bolus is easy to swallow and is formed
when saliva and other fluids in the mouth mixed with mucous. Bolus slides past the epiglottis and
then goes through the esophagus and to the stomach where it is then digested. The esophagus is a
muscular tube connecting the pharynx to the stomach that is part of the upper gastrointestinal tract.
(4) This organ carries the

The Function Of The Human Digestive System
The human digestive system is like a machine composed of many parts of the body that work
together to turn foods and liquids into energy that the body requires to function.
The digestive tract begins with the mouth. This is where the enzyme amylase is released to initiate
the process of digestion.
The epiglottis is a small piece of tissue that covers the opening of the larynx.
Once food passes through the epiglottis, it goes to the gallbladder, a small pouch that stores bile.
The gallbladder releases bile into the duodenum to help digest fats in the food you eat.
The first part of the small intestine is called the duodenum. The word duodenum comes from the
Latin word duodeni and means "12 each." The duodenum was thought to be as long as the width of
12 fingers.
The middle section of the small intestine is called the jejunum, which is about 5 to 8 feet (1.5 to 2.5
meters) long.
The third part of the small intestine is called the ileum. It's also the longest tube, measuring 16 to 20
feet (5 to 6 meters) long.
It is called small intestine because of its width, not its length. The small intestine is actually much
longer than the large intestine. The small and large intestines form one continuous tube.
The large intestine consists of three parts, the cecum, the colon, and the rectum. The cecum is the
pouch–like beginning of the large intestine. The colon is the largest part of the large intestine and
has three parts – the ascending colon, the transverse colon, and the

The Human Digestive System Essay
When we eat, the nutrients and energy we need in order to function have to be extracted from food
and absorbed into the body. The process responsible for this is known as digestion. The human
digestive system has to be able to process our omnivorous feeding habits and diet, and has adapted
this to function at an optimum level and is controlled by our autonomic nervous system by the brain.
The digestive system is a collective of automated processes and organs, enzymes, secretions, some
accessory organs and a pipework (or tube) that starts at the mouth and ends at the anus, known as the
alimentary. The processes that take place along the alimentary canal are how we take in these
various nutrients, differentiate what that body can use for...show more content...
The sphincter prevents the fodd from travelling back up the oesophagus, except in the event of
vomitting. The stomach is a sack positioned within the abdominal cavity, just below the diaphragm.
The purpose of the stomch is to hold, reduce and process food before it is passed through into the
colon for absorbtion of nutrients, minerals and other necessary properties, before passing out of the
body as waste. Within the stomach, the food is 'churned' up by peristaltic muscle contractions, and is
liquidised further by the addition of gastric juices. These gastric juices contain water, salts and an
enzyme called Protease. Protease helps to convert the protein in food into amnio acids which are
then absorbed through the walls of the stomach and further down through the digestive tract. The
stomach also contains hydrochloric acid which destroys any bacteria in food. It is highly acidic and
would cause a chemical burn if in contact with the skin. The stomach contains a mucus which
prevents this acid from burning the internal lining of the stomach, and stop it from digesting itself.
When this fails, the stomach develops ulcers. The acidity level of the stomach is so high that it
literally burns the stomach lining if these ulcers occur. When the food has been reduced within the
stomach, it leaves by another sphincter and enters the small intestine (or duodenum) as chyme, the
name given to this

Digestive System Journey
The digestive system is the process of turning food that we eat into nutrients that the body uses for
energy. This system also creates waste that the body needs to eliminate. We are now going to talk
about the journey of food through the digestive system to see how everything works together to
reserve the nutrients of the food we take in everyday and how the body removes all the remaining
substances from our body.
As I enter the mouth, there is already I liquid that the salivary glands have produced because of the
scent of my delicious smell. The teeth begin to chop and grind me up into smaller pieces and with
the help of the saliva, it breaks down the chemicals that created from , making it easier for them to
swallow me. The saliva will help me through my twelve hour thirteen foot journey in the digestive
system. The tongue then starts forming me into a small ball like shapes, and once it begins
contracting it sends me back into the pharynx, also called the throat, and into the opening of the
esophagus. The esophagus is a stretchy like tube that is about 10 inches long that I travel through to
get to the opening of the stomach.
Once I reach the stomach, I am accompanied with other processed food. The stomach then used its
gastric juices to make us thinner. We are now sitting...show more content...
What remains of us is now being moved into the large intestine through the ileocecal sphincter,
which is a valve that separates the small and large intestine and keeps us from going back to where
we came from. What is left of us is a mix of waste that the small intestine didn't need and dead cells
of the wall of the gut. The large intestines main job is to remove all the water of our composition
and is sent off into the bloodstream. Once the water is removed, bacteria suuround us and produce
enzymes that break down our complex carbohydrates that the body could not

Essay about The Importance of Digestive System
How is it so that something as simple as a piece of steak can be turned into fuel for our bodies once
it is consumed? It happens through this one system with many functioning parts known as the
digestive system. When it comes to the human body the digestive system is very important. It gives
our bodies the ability to process foods, extract the nutrients we need from the foods, and eliminate
the wastes (smartlivingnetwork). Without these abilities our bodies wouldn't be able to function. So
what is the digestive system exactly? It is a complex series of organs that processes the food we eat.
Altogether this system is about 6–9 meters of muscular tubes running from the mouth to the anus.
According to Robert Sullivan, the organs of this...show more content...
Nucleases are enzymes that split nucleic acids into nucleotides and other products. Protease is an
enzyme that catalyzes the hydrolytic breakdown of proteins. Amylase is an enzyme that catalyzes
the hydrolysis if starch to sugar to produce carbohydrate derivatives. Trypsin is an enzyme
produced by the exocrine pancreas that catalyzes in the small intestine the breakdown of dietary
proteins to peptones, peptides, and amino acids. Lipase is an enzyme that splits the fatty acid
residue from the glycerol residue in a phospholipid. Collagenase catalyzes the hydrolysis of collagen
and gelatin. Elastase catalyzes the digestion of elastic tissue. Chymotrypsin catalyzes the hydrolysis
if casein and gelatin.
The Process of the Digestive System This complicated process begins in the mouth as soon as you
put the food in your mouth. Salivary amylase, which is found in saliva, starts the chemical
digestion of starch by converting it from a polysaccharide to the disaccharide maltose. It functions
best with a pH 6 or 7 which is slightly acidic. It then enters the pharynx and travels down the
esophagus and into the stomach. The stomach is lined with strong muscular walls that contain
millions of gastric glands. Our food is mechanically digested by our stomach's walls while its
enzymes and acids chemically digest it. Just about everything then goes into the liver to be
metabolized except for fats.

Digestive Systems And The Digestive System Essay
When choosing between what system to write about, I thought the digestive system would be a
good topic because food is probably one of my favorite things, not only cause it tastes good but
because it gives me the energy to do all the things I need to do throughout the day. We talked in
class about how you should always get the nutrients from food and never from supplements, which
I've always tried to do. So, what is the digestive system? The digestive system is an assortment of
organs that performs the process of digestion. The process of digestion involves food, containing
nutrients, which is eaten and broken down into different segments. The digestive system also works
with additional important systems in the body such as the circulatory system and the excretory
system. The circulatory system receives all the absorbed nutrients through your body, and your
excretory system filters compounds from the blood stream and collects them in urine. This whole
system is designed distinctively, with the ultimate goal of turning food into the energy that you need
to survive. The digestive system starts with the mouth and ends with the anus. (Studios, A. R, n.d)
The mouth is the very beginning of the digestive tract, and is literally where the first bite of food
is taken. Chewing food breaks down the food into little pieces, while saliva mixes with the food to
assist with the process of breaking it down. After the food has been broken down, it enters the
esophagus, which is in essence,

Reflection On The Digestive System
Once upon a time, I was visiting with my friends just shooting the breeze. My name is C.B., and
I'm a cheeseburger. I was with my best friend PC, also known as potato chip, and then of course,
my girlfriend Cookie. We are a great pack and always do everything together. Sometimes we like
to explore, but on this particular night, we ended up in a room among a bunch of adults laughing
and drinking. Now, we've all heard stories about this object called a hand. Supposedly, once this
hand picks you up, you will never come back. Of course, we thought it was all a big joke until this
night. Brace yourself as you follow my journey. Although I have read about a digestive system, I
never thought I would enter one. All of the organs in a body have a job to do, and they rely on
each other to do their part as a team, similar to working on a long conveyor belt. Besides breaking
food down into smaller components, the digestive system also has to absorb In order for these
components to fit into the bloodstream. There are two parts, the mechanical and the chemical
digestion. Between my friends and I, there's cheese, bread, butter, eggs, flour, potatoes, sugar, and
other ingredients. Do you know what this means? Bread has carbohydrates and fiber, cheese has
fat, and butter has mostly all fat. We are all in big trouble, and we are about to face the same fate.
Immediately after being spotted, I'm picked up and placed inside this mouth where I know
