Question

Where does digestion complete?

Answer 1

Human digestive system:

The human digestive system consists of a group of components that work together to convert food into energy for the body.

Completion of digestion:

1. Chewing and ingesting begin digestion in the mouth, and it concludes in the small intestine.
2. There are three portions of the small intestine: the first part is the duodenum, the jejunum is in the center and the ileum is at the end.
3. The small intestine has tiny, finger-like folds known as villi.
4. The microvilli, which are tiny protrusions made by the cells bordering the villi, produce a brush border.
5. Villi and microvilli greatly increase the surface area of the small intestine for absorption.
6. Food is broken down in the small intestine using bile from the liver and enzymes secreted by the pancreas.
7. The duodenum area of the small intestine is where biomacromolecules (proteins, carbs, lipids, and nucleic acids) are broken down.
8. The small intestine's jejunum and ileum sections are where the simple chemicals that are so created are absorbed.
9. Pancreatic amylase hydrolyzes the chyme's carbohydrates into disaccharides.
10. Enzymes including sucrase, maltase, and lactase hydrolyze tiny glucose polymers and disaccharides into monosaccharides.
11. The proteolytic enzymes of the pancreas and intestinal mucosa break down proteins in the small intestine.
12. The main proteases found in pancreatic enzymes include proelastase, carboxypeptidase, trypsin, and chymotrypsin.
13. The polypeptides are broken into tripeptides, dipeptides, and amino acids by proteolytic enzymes in the small intestine.
14. Pancreatic lipase converts triglycerides into fatty acids and monoglycerides.
15. The pancreatic nucleases break down nucleic acids into nucleotides in the intestine.
16. The cecum, colon, rectum, and anal canal are the four sections of the large intestine.
17. The cecum refers to the first portion of the large intestine.
18. The large intestine receives the compounds that were not digested and were not absorbed.
