Question

Where does digestion end in the human body?

Answer 1

Hint: In the process of digestion large food particles are broken down to simpler molecules. These tiny molecules are taken into the bloodstream by some organisms through the small intestine. Catabolism occurs when big food molecules (polysaccharides, proteins, lipids, and nucleic acids) are broken down into smaller ones (i.e., monosaccharides, amino acids, fatty acids, nucleotides)

Complete answer:
Digestion ends in the small intestine of the human body.
The digestive process starts in the mouth and finishes in the small intestine; the large intestines' primary role is to absorb any residual water from undigested food and here the undigested food is fermented by the bacteria.
Food is moved through the GI system during digestion. Food interacts with digestive fluids as it travels through the GI system, causing big food molecules to break down into smaller ones. The body subsequently absorbs these smaller molecules via the small intestine's walls and into the circulation, where they are distributed throughout the body. The digestive waste products travel via the large intestine and are finally defecated through the rectum and anus.

Note:
The numerous digestive fluids generated at various stages and sections of the digestive tract all have the same function: to act on certain foods. Each juice is made to break down carbs, proteins, and lipids and aid in their digestion. Saliva is expelled from the mouth, whereas gastric fluid is expelled from the stomach. Bile, pancreatic juice, and intestinal juice are the three types of digestive juices which aid in the digestion process in the small intestine.
