The human digestive system breaks down food into nutrients that can be absorbed and used by the body. Ingested food moves through the digestive tract, where it is broken down mechanically by chewing and enzymatically by digestive juices. The major organs involved include the mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas and gallbladder. In the small intestine, nutrients are absorbed into the bloodstream. Undigested material then moves to the large intestine where water is reabsorbed before waste is excreted.

Different Digestive process for absorption of food in GIT.
Different parts GIT Tract where food move from Mouth to the anus.
The document summarizes the key stages of human digestion. It begins with ingestion in the mouth where food is broken down mechanically by teeth and chemically by saliva. It then moves to the stomach where food is further broken down chemically by gastric juices and mechanically. Accessory organs like the liver, pancreas and gallbladder also secrete substances that aid in digestion. The small intestine is the primary site of absorption, where nutrients are absorbed through the villi. Undigested waste then moves to the large intestine where water is reabsorbed before waste is eliminated through the rectum.
The digestive system breaks down food through mechanical and chemical digestion to extract nutrients for absorption. It involves both organs of the gastrointestinal tract - the mouth, esophagus, stomach, small intestine, large intestine - and accessory organs like the liver, gallbladder and pancreas. Food is ingested, broken down through peristalsis, enzymes, and absorption of nutrients occurs in the small intestine. Indigestible waste is eliminated as feces.
This document discusses ruminant digestion, including the anatomy and functions of ruminant digestive systems. Key points include:
- Ruminants have a four-chambered stomach (rumen, reticulum, omasum, abomasum) that allows them to digest cellulose with the help of microbes in the rumen.
- The rumen ferments ingested plant material and can regurgitate and rechew contents in a process called rumination.
- Each stomach compartment has a distinct capacity and function in digestion. The rumen makes up most of the stomach volume and serves as a storage area.
- Accessory organs like the liver and pancreas produce enzymes and

The document provides guidance for an IB Biology course on the digestive system. It outlines six understandings about the small intestine, including that circular and longitudinal muscles mix food and enzymes and move it along, the pancreas secretes digestive enzymes, and villi absorb digested monomers. It also lists two applications, including the processes of starch digestion and transport to the liver, and using dialysis tubing to model absorption. Finally it provides guidance on two skills, producing an annotated diagram of the digestive system and identifying tissue layers in the small intestine.
Digestion and absorption, digestive secretions, their characteristic features: Digestion is the breakdown of food into particles small enough to cross the cellular barrier of the gastrointestinal (GI) system and be carried around the body in the circulation.
This occurs by both mechanical and chemical processes that begin in the mouth and generally end in the small intestine, where 90% of absorption takes place.
The other 10% takes place in the stomach and large intestine and often involves the help of the gut microbiota.
A small amount of absorption is also thought to take place in the mouth.
Mechanical digestion begins in the mouth with chewing and continues with segmental muscle contractions in the stomach and intestines.
Chemical digestion is primarily mediated by enzymes present in the secretions of the salivary glands, stomach and pancreas, and on the epithelial lining of the small intestine
Mechanical digestion is physical process in which food is broken into smaller pieces without chemically.
It begins with our first bite of food and continues as we chew food with our teeth into smaller pieces.
The process of mechanical digestion continues in the stomach. This muscular organ churns and mixes the food it contains, an action that breaks any solid food into still smaller pieces.
Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body.
Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.
Carbohydrates must be broken down into simple sugars, proteins into amino acids, lipids into fatty acids and glycerol, and nucleic acids into nitrogen bases and sugars.
Some chemical digestion takes place in the mouth and stomach, but most of it occurs in the first part of the small intestine (duodenum).
Chemical digestion could not occur without the help of many different digestive enzymes. Enzymes are proteins that catalyze or speed up biochemical reactions.
Digestive enzymes are secreted by exocrine glands or by the mucosal layer of the epithelium lining the gastrointestinal tract.
In the mouth, digestive enzymes are secreted by salivary glands.
The lining of the stomach secretes enzymes, as does the lining of the small intestine.
Many more digestive enzymes are secreted by exocrine cells in the pancreas and carried by ducts to the small intestine
About 80 percent of digestible carbohydrates in a typical Western diet are in the form of the plant polysaccharide amylose, which consists mainly of long chains of glucose and is one of two major components of starch.

The Human Digestive Organs and its function making it a System.pptxALVINMARCDANCEL2
This is a comprehensive powerpoit presentation on the parts and functions of digestive system.Human digestive system, system used in the human body for the process of digestion. The human digestive system consists primarily of the digestive tract, or the series of structures and organs through which food and liquids pass during their processing into forms that can be absorbed into the bloodstream. The system also consists of the structures through which wastes pass in the process of elimination and of organs that contribute juices necessary for the digestive process.
In order to function properly, the human body requires nutrients. Some such nutrients serve as raw materials for the synthesis of cellular materials, while others help regulate chemical reactions or, upon oxidation, yield energy. Many nutrients, however, are in a form that is unsuitable for immediate use by the body; to be useful, they must undergo physical and chemical changes, which are facilitated by digestion.
The digestive system consists of the digestive tract and accessory organs. The six main functions of the digestive system are ingestion, mechanical and chemical digestion, secretion, absorption, and excretion. The digestive tract includes the mouth, esophagus, stomach, small intestine, and large intestine. Accessory organs that aid in digestion include the teeth, tongue, salivary glands, liver, gallbladder and pancreas. In the small intestine, nutrients are absorbed into the bloodstream and lymphatic system.

The document discusses human digestion and the human digestive system. It describes the process of ingestion and digestion, the types of nutrients, and the major organs involved in digestion including the mouth, stomach, small intestine, large intestine, and associated organs like the liver, gallbladder and pancreas. It provides details on the functions of these organs and enzymes involved at each stage of digestion.
The small intestine functions to further digest and absorb nutrients from food. It is divided into three sections - the duodenum, jejunum, and ileum. The small intestine contains villi and microvilli that increase its surface area for absorption. Digestion and absorption continue in the small intestine through the actions of succus entericus and bile. The large intestine absorbs water and electrolytes from undigested material and forms feces from waste products.
The human digestive system breaks down food into smaller molecules that can be absorbed and used by the body. It begins in the mouth and includes the esophagus, stomach, small intestine, large intestine, and anus. Digestion involves both mechanical and chemical breakdown of food. The digestive system works with other organs like the liver, pancreas, and salivary and gastric glands to break down proteins, fats, and carbohydrates into nutrients that can be absorbed and used for energy, building materials, and other functions in the body. A balanced diet and healthy lifestyle are important for maintaining a properly functioning digestive system.
The document summarizes the human digestive system and nutrition. It discusses the two parts of nutrition - ingestion and digestion. It then describes the mouth, esophagus, stomach, pancreas, liver and gallbladder. The mouth chews and moistens food. The stomach stores, kills germs in, and breaks down food through acid and enzymes. The pancreas produces enzymes to digest proteins, carbs and fats. The liver produces bile to break up fats for absorption.
