Absorption of Digested Food

Hey All AIPMT Biology Aspirants, read out the next AIPMT Biology Study material/ Notes of Absorption of Digested Food, useful for AIPMT Biology.

Absorption of Digested Food

  • Breakdown of bio-macromolecules during digestion basically occurs in duodenum region of the small intestine.
  • Simple substances formed are absorbed in the jejunum and ileum regions

Mechanism of digestion in Small Intestine

Chyme entering the small intestine contains partially digested carbohydrates (maltose), proteins (proteoses and peptides), and lipids (monoglycerides).

  • Completion of the digestion of carbohydrates, proteins, and lipids is a collective effort of pancreatic juice, bile juice, and intestinal juice in the small intestine.
  • Movements of muscularis layer of the small intestine help in

Mechanism of Digestion

Digestion is a process of breaking down larger insoluble food particles into smaller water-soluble molecules that can be easily absorbed by the body cells.

  • Alimentary canal/Digestive tract/ Gastrointestinal (GI) tract is a continuous tube from mouth to anus.
  • Six basic processes performed by digestive system are:
    1. Ingestion: Taking

Mechanism of digestion in Stomach

Hello all AIPMT Biology Aspirants, Learn about chyme, Digestion in Stomach.

Food (Bolus) comes to stomach after travelling through esophagus. It takes about 4 to 8 seconds to travel through esophagus.

  • Stomach stores the food for 4-5 hours. So, stomach acts as a reservoir for food before release into small intestine.
  • Food mixes
