What are the major products of digestion?
Lipids, proteins, and complex carbohydrates are broken down into small and absorbable units (digested), principally in the small intestine. The products of digestion, including vitamins, minerals, and water, which cross the mucosa and enter the lymph or the blood (Absorption).
end products are amino acids. Carbohydrates: Polysaccharides are broken down by salivary amylase enzyme, so the final products are monosaccharides such as glucose, galactose, fructose, etc. Fats: The end-products of fats are fatty acids and glycerol.
Figure 2: The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.
The digestive system carries out three primary processes: mixing food, moving food through the digestive tract (peristalsis) and using chemicals to break down food into smaller molecules.
The final products from the digestion of carbohydrates, proteins, and fats are sugars, amino acids, fatty acids, and glycerol respectively.
The final products after digestion of carbohydrates, proteins and fats are sugars - glucose, proteins - amino acids and fats - fatty acids and glycerol respectively.
The digestive system is composed of the alimentary canal and associated glands. Humans take food through the mouth, digest the food and finally, the undigested food is removed from the body. The food passes from the oral cavity and finally, the undigested food is defecated through the anus.
The human digestive system consists of the buccal cavity, oesophagus, stomach, small intestine, large intestine ending in rectum and anus. The human digestive tract is also called an alimentary canal. The digestive tract and associated glands like salivary glands, liver and pancreas make up the digestive system.

The four basic types of digestive systems in animals are monogastric, avian, ruminant, and pseudo-ruminant.
What are the 4 main parts of the digestive process?
Motility, digestion, absorption and secretion are the four vital functions of the digestive system. The digestive system breaks down the foods we eat into energy our bodies can use.
Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive. The digestion process also involves creating waste to be eliminated.
Why is digestion important? Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
This digestion or catabolism is divided into two types – the mechanical digestion of food that occurs in the mouth when it is physically broken up into smaller pieces and the chemical digestion that occurs in the gastrointestinal tract when the food is broken down into small molecules by digestive enzymes.
The digestive tract, also called the alimentary canal or gastrointestinal (GI) tract, consists of a long continuous tube that extends from the mouth to the anus. It includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine.
Large carbohydrate molecules are digested and transformed into monosaccharides like glucose. Protein molecules are broken down into amino acids. Fats are broken down into fatty acids and glycerol.
Hence, the end product of protein digestion is amino acids.
The end products of fat digestion are fatty acids and glycerol. Bile is a green fluid secreted by the liver that helps in the digestion of fats.
Digestion and absorption of carbohydrates
Amylase hydrolyzes starch, with the primary end products being maltose, maltotriose, and a -dextrins, although some glucose is also produced.
The stomach is a J-shaped organ that digests food. It produces enzymes (substances that create chemical reactions) and acids (digestive juices). This mix of enzymes and digestive juices breaks down food so it can pass to your small intestine. Your stomach is part of the gastrointestinal (GI) tract.
What are villi what is their location and function for Class 7?
Villi are finger-like projections which are richly supplied with blood vessels. They are present in the inner lining of the small intestine and help in the absorption of nutrients by increasing the surface area for absorption.
Digestive enzymes such as amylase, lipase, pepsin, trypsin, etc., help in the chemical digestion of food by breaking down complex food particles into simpler ones. These simple molecules can be easily absorbed by the blood and is thus transported to all the cells in the body.
The digestive system of the human body is the sum of the gastrointestinal tract (GIT; also called alimentary canal) and accessory organs (tongue, liver, pancreas, etc.). These two parts together help in the digestion process. The alimentary canal is the long tube through which the food that we eat is passed.
Our stomach churns the food to digest it. Digestive juices present in the stomach mix with the food and help in digestion.
Digestion is defined as the process of breaking down large, insoluble molecules of food into smaller, water-soluble molecules which can then be readily absorbed by the body.
Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins.
Bile juice is stored in a small organ called the gall bladder. Here, bile is concentrated before it is released into the small intestine where it helps in the digestion of fats or lipids. Q. Bile juice is secreted by the liver and it helps in the breakdown of proteins.
The large intestine includes the colon, rectum and anus. It's all one, long tube that continues from the small intestine as food nears the end of its journey through your digestive system. The large intestine turns food waste into stool and passes it from the body when you poop.
The digestive system is made up of organs that are important for digesting food and liquids. These include the mouth, pharynx (throat), esophagus, stomach, small intestine, large intestine, rectum, and anus.
The process of digestion has three stages: the cephalic phase, the gastric phase, and the intestinal phase. The first stage, the cephalic phase of digestion, begins with secretions from gastric glands in response to the sight and smell of food.
What is digestion example?
In physiology, digestion pertains to the mechanical and chemical processes to break up food into smaller or simpler constituent parts that can be absorbed or assimilated. Different organisms utilize different ways to digest food. Some organisms employ external digestion whereas others use internal digestion.
Digestion is the process of breaking down complex food materials into simpler substances by the action of enzymes. Need for a digestive system: Large complex molecules like carbohydrates, proteins and lipids need to be broken down to simpler molecules.
Food moves through the digestive system with a wave-like motion called peristalsis. Muscles in the walls of the hollow organs contract and relax to cause this movement, which pushes food through the esophagus into the stomach.
Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
Answer and Explanation: a. filtration is NOT a function of the digestive system. The breakdown of food in the digestive system starts with ingestion and mechanical...
Physical digestion is the mechanical breakdown of food. Physical digestion in the mouth includes chewing, which masticates, or grinds, food. Chemical digestion in the mouth is done by salivary amylase which is the enzyme in the saliva that breaks down complex carbohydrates into simple sugar.

Two important functions of the digestive system are digestion and absorption. The nutrients that come from food are derived from proteins, fats, carbohydrates, vitamins, and minerals. These complex macromolecules must be broken down and absorbed in the gastrointestinal (GI) tract.
Regions of the digestive system can be divided into two main parts: the alimentary tract and accessory organs. The alimentary tract of the digestive system is composed of the mouth, pharynx, esophagus, stomach, small and large intestines, rectum and anus.
Stomach: An organ with strong muscular walls, the stomach holds the food and mixes it with acid and enzymes that continue to break the food down into a liquid or paste. Small Intestine (Small Bowel): Almost 20 feet long, the small intestine is the workhorse of the digestive system.
Which of the following is not a function of the liver?
Thus, the correct answer is 'Absorption of food and excess water from the undigested food. '
Bile is essential for digesting fats and for eliminating worn-out red blood cells and certain toxins from your body. Bile is produced in your liver and stored in your gallbladder.

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair.
The end products of fat digestion are fatty acids and glycerol.
So, the chemical digestion of protein starts in the stomach and ends in the small intestine. Hence, the end product of protein digestion is amino acids.
Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.
