Sep 25, 2023

Are there specific enzymes responsible for digesting different types of nutrients?

Yes, various enzymes in the digestive system are specialized in breaking down proteins, carbohydrates, and fats.
Fiza Rafique
Sep 25, 2023

Can ingestion occur without digestion following it?

Ingestion typically precedes digestion, as the digestive process starts in the mouth with chewing and saliva mixing with food.
Fiza Rafique
Sep 25, 2023

How does the body absorb the nutrients produced during digestion?

Nutrients produced during digestion are absorbed through the walls of the small intestine into the bloodstream, where they are transported to cells throughout the body.
