Where does both mechanical and chemical digestion occur?
Digestion is a process that converts nutrients in ingested food into forms that can be absorbed by the gastrointestinal tract. Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine.
What is the first place mechanical digestion takes place?
Mechanical digestion begins in your mouth with chewing, then moves to churning in the stomach and segmentation in the small intestine. Peristalsis is also part of mechanical digestion.
What two organs perform both mechanical and chemical digestion?
The organs that perform both mechanical digestion and chemical digestion are the mouth and the stomach.
What is the initial site of protein chemical digestion?
What is digestion absorption?
Absorption. The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.
Why protein is not absorbed in the body?
Your body can’t absorb proteins in their natural state. Certain proteases in your stomach and pancreas break the bonds that hold the amino acids in protein together so your body can absorb the composite amino acids individually.
Where does the digestion of protein start in our body * 1 point?
Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.
How is food digested step by step?

What are the 4 stages of digestion?
There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food. The mechanical breakdown of food occurs via muscular contractions called peristalsis and segmentation.
What are the 7 steps of digestion?
The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.
How stool is formed?
As part of the digestion process, or due to fluid intake, food is mixed with large amounts of water. Thus, digested food is essentially liquid prior to reaching the colon. The colon absorbs water, leaving the remaining material as a semisolid stool.
