Name the part of the alimentary canal where major absorption of digested food takes place. What are the absorbed forms of different kinds of food materials?
Answer :
The part of the alimentary canal where major absorption of the digested food takes place is small intestine.
The biomacromolecules of food are converted into simple substances in duodenum region of the small intestine.
The simple substances thus formed are absorbed in the jejunum and ileum regions of the small intestine.
Small intestine has small finger like folding called Villi. Villi produce numerous microscopic projections called microvilli.
Microvilli increase the surface area enormously.
Villi are supplied with a network of capillaries and a large lymph vessel called the lacteal.
In small intestine the carbohydrates is absorbed in the form of glucose, proteins are absorbed in the form of amino acids and fats are absorbed in the form of fatty acids and glycerol.
So the absorbed forms of different kinds of food materials are amino acids, monosaccharide, fatty acids and glycerol.
