The document summarizes the key parts and functions of the human digestive system. It begins with ingestion in the mouth, where food is broken down mechanically by teeth and chemically by saliva. It then travels to the stomach through swallowing, where further digestion occurs through gastric juices and the food is broken down into a liquid called chyme. Chyme then enters the small intestine where most digestion and absorption takes place, aided by enzymes from the pancreas, liver and gallbladder. Undigested waste then progresses to the large intestine where water is absorbed before waste is excreted through the rectum.

Constipation is generally defined as infrequent and/or unsatisfactory defecation fewer than 3 times per week.
Patients may define constipation as passing hard stools or straining, incomplete or painful defecation. It's a symptom NOT a disease.
Constipation has many causes and may be a sign of undiagnosed disease.
Diarrhea is a very common daily based issue with lots of contributing factors. The need is to determine the underlying causes, otherwise the consequences may get worsen.

Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).
The world of search engine optimization (SEO) is buzzing with discussions after Google confirmed that around 2,500 leaked internal documents related to its Search feature are indeed authentic. The revelation has sparked significant concerns within the SEO community. The leaked documents were initially reported by SEO experts Rand Fishkin and Mike King, igniting widespread analysis and discourse.

2. Nutrition
Process by which organisms obtain and utilize their food.
There are two parts to Nutrition:
1. Ingestion- process of taking food into the
digestive system so that it may be
hydrolized or digested.
2. Digestion- the breakdown of food (either
chemically or mechanically) in order to
utilize nutrients
3. Types of Nutrients
• Micronutrients- vitamins, minerals, & water
• Macronutrients- proteins, lipids,
carbohydrates, etc…
9. Swallowing (& not choking)
• Epiglottis
– flap of cartilage
– closes trachea (windpipe) when swallowing
– food travels down esophagus
• Peristalsis
– involuntary muscle contractions to move food along
10. Which type of digestion is the
following?
1. Chewing a saltine? -
2. Saliva breaking the saltine down into molecules of
glucose? -
3. Your tongue breaking pieces of a hamburger apart?
4. Pepsin (an enzyme) in your stomach breaking the
hamburger into amino acids?
11. Pharynx
• The back of the
throat.
• Larynx-
passage for air,
closes when we
swallow.
• Is approximately
15cm long.
12. Digestive Glands
• Groups of
specialized
secretory
cells.
• Found in the
lining of the
alimentary
canal or
accessory
organs.
13. • series of involuntary
wave-like muscle
contractions which
move food along the
digestive tract
Peristalsis
14. Stomach
• Food is temporarily
stored here.
• Gastric juices are
secreted.
• Has layers of
muscle that line the
inside.
• Mechanically and
chemically breaks
down food.
15. Stomach
• Functions
– food storage
• can stretch to fit ~2L food
– disinfect food
• HCl = pH 2
– kills bacteria
– chemical digestion
• pepsin
– enzyme breaks down proteins
But the stomach is made out of protein!
What stops the stomach from digesting itself?
mucus secreted by stomach cells protects
stomach lining
17. Gastric Juices
• Secreted by the
stomach.
• Acidic (pH 1.5-2.5)
(HCl).
• Pepsin- an enzyme that
breaks down large
proteins into amino
acids.
• Food is further broken
down into a thin liquid
called chyme.
20. Gall bladder
• Pouch structure located near the liver
which concentrates and stores bile
• Bile duct – a long tube that carries BILE.
The top half of the common bile duct is
associated with the liver, while the bottom
half of the common bile duct is associated
with the pancreas, through which it passes
on its way to the intestine.
21. BILE
• Bile emulsifies lipids (physically breaks
apart FATS)
• Bile is a bitter, greenish-yellow alkaline
fluid, stored in the gallbladder between
meals and upon eating is discharged into
the duodenum where it aids the process of
digestion.
22. Pancreas
• An organ which secretes both digestive
enzymes (exocrine) and hormones (endocrine)
• ** Pancreatic juice digests all major nutrient
types.
• Nearly all digestion occurs in the small intestine
& all digestion is completed in the SI.
25. Liver
• Function
– produces bile
• bile stored in gallbladder until needed
• breaks up fats
– act like detergents to breakup fats
bile contains
colors from old
red blood cells
collected in liver =
iron in RBC rusts &
makes feces brown
26. pancreas
produces enzymes to
digest proteins & starch
stomach
kills germs
break up food
digest proteins
store food
mouth
break up food
digest starch
kill germs
moisten food
liver
produces bile
- stored in gall bladder
break up fats
27. Small Intestine
• Most chemical
digestion takes place
here.
• Simple sugars and
proteins are absorbed
into the inner lining.
• Fatty acids and
glycerol go to lymphatic
system.
• Lined with villi, which
increase surface area for
absorption, one cell
thick.
28. Small intestine
• Function
– chemical digestion
• major organ of digestion & absorption
– absorption through lining
• over 6 meters!
• small intestine has huge surface area = 300m2
(~size of tennis court)
• Structure
– 3 sections
• duodenum = most digestion
• jejunum = absorption of nutrients & water
• ileum = absorption of nutrients & water
29. Duodenum
• 1st section of small intestines
– acid food from stomach
– mixes with digestive juices from:
pancreas
liver
gall
bladder
30. stomach
kills germs
break up food
digest proteins
store food
mouth
break up food
digest starch
kill germs
moisten food
pancreas
produces enzymes to
digest proteins & starch
31. Absorption in the SI
• Much absorption is thought to occur directly through the wall
without the need for special adaptations
• Almost 90% of our daily fluid intake is absorbed in the small
intestine.
• Villi - increase the surface area of the small intestines, thus
providing better absorption of materials
32. Absorption by Small Intestines
• Absorption through villi & microvilli
– finger-like projections
– increase surface area for absorption
34. Large intestines
(colon)
• Function
– re-absorb water
• use ~9 liters of water every
day in digestive juices
• > 90% of water reabsorbed
– not enough water absorbed
» diarrhea
– too much water absorbed
» constipation
35. Large Intestine
• Solid materials pass
through the large
intestine.
• These are undigestible
solids (fibers).
• Water is absorbed.
• Vitamins K and B are
reabsorbed with the
water.
• Rectum- solid wastes
exit the body.
36. You’ve got company!
• Living in the large intestine is a
community of helpful bacteria
– Escherichia coli (E. coli)
• produce vitamins
– vitamin K; B vitamins
• generate gases
– by-product of bacterial metabolism
– methane, hydrogen sulfide
38. Rectum
• Last section of colon
(large intestines)
– eliminate feces
• undigested materials
– extracellular waste
» mainly cellulose
from plants
» roughage or fiber
– masses of bacteria
39. Digestive Homeostasis Disorders
• ULCERS – erosion of the surface of the
alimentary canal generally associated
with some kind of irritant
40. • CONSTIPATION – a
condition in which the
large intestine is emptied
with difficulty.
• Too much water is
reabsorbed
• and the solid waste
hardens
Digestive Homeostasis Disorders
41. Digestive Homeostasis
Disorders
• DIARRHEA – a gastrointestinal
disturbance characterized by
decreased water absorption and
increased peristaltic activity of
the large intestine.
• This results in increased,
multiple, watery feces.
• This condition may result in
severe dehydration, especially in
infants
43. Digestive Homeostasis
Disorders
• GALLSTONES – an accumulation of
hardened cholesterol and/or calcium
deposits in the gallbladder
• Can either be “passed” (OUCH!!) or
surgically removed
44. Digestive Homeostasis
Disorders
• ANOREXIA NERVOSA - a psychological
condition where an individual thinks they
appear overweight and refuses to eat.
• Weighs 85% or less than what is
developmentally expected for age and
height
• Young girls do not begin to menstruate at
the appropriate age.
