The first is mechanical digestion by chewing, grinding, churning and mixing that takes place in the mouth and the stomach. The second part of digestion is the chemical digestion that uses enzymes, bile acids etc.
Where is digested food absorbed in the body Class 7?
Answer: The digested food is absorbed inside the small intestine which have finger like projections called villi in its inner wall. These villi comprise networks of fine blood capillaries close to their surface. The food from the villi passes into these capillaries thereby getting absorbed into the blood.

Which cell absorbs the digested food?
Villi are lined by columnar epithelial cells that produce numerous microscopic projections called microvilli. They increase the surface area for the absorption of digested food.
What type of digestion occurs in the large intestine?
Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.

Does mechanical digestion occur in the large intestine?
In the large intestine, mechanical digestion begins when chyme moves from the ileum into the cecum, an activity regulated by the ileocecal sphincter. Right after you eat, peristalsis in the ileum forces chyme into the cecum.
What is the proper order of the following stages of food processing?
What is the proper order of the following stages of food processing-defecation, absorption, digestion, and ingestion? Ingestion, digestion, absorption, and defecation. How do mechanical and chemical digestion differ from each other? Mechanical digestion breaks food down physically by squeezing and pummeling it.
