the b12 intrinsic factor produced by the parietal cells in the stomach (parietal cells also produce HCL, the acid that dissolves food and converts pesinogen (secreted by the chief cells). B12 is necessary for carbohydrate, protein and fat to be used by the boy but most importantly b12 is necessary for all cells in the body (especially red blood cells) to work properly; if deficient in the body the person may develop pernicious anemia (due to the excessive destruction of immature blood cells or the lack of their production due to a lack of vitamin b12) as well as other problems such as problems with the nervous system sue to the fact that b12 is used to cover nerve cells thus the lack of vitamin b12 can also get to the brain and in kill the person. The intrinsic factor secreted by the stomach's parietal cells is used to absorb vitamin b12 as the body cannot absorb it on its own. As a result the intrinsic factor is essential for life as there will be vitamin vb12 deficiency if there is no intrinsic factor to help the boy absorb it. Another important fact is that vitamin b12 is absorbed( with the help of the intrinsic factor) by cubulin receptors in the ileum of the small intestine.
What else can I help you with?
The most important function of the stomach and perhaps the only function that appears to be essential for life is the?
secretion of intrinsic factor
Aids in absorption of vitamin b12?
Intrinsic factor, a protein produced in the stomach, helps in the absorption of vitamin B12. This vitamin is crucial for red blood cell formation and neurological function. Absorption of vitamin B12 occurs in the small intestine, where it binds to intrinsic factor for transport into the bloodstream.
Which cells produce intrinsic factor?
Intrinsic factor is produced in the fundus and body of the stomach by parietal cells that line the stomach. The purpose of intrinsic factor is so vitamin B can be absorbed in the small intestine.
Which cells of the stomach secretes hydrochloride acid and intrinsic factor?
The parietal cells of the stomach are responsible for secreting hydrochloric acid, while the chief cells secrete intrinsic factor. These two secretions are important for the digestion of food and absorption of nutrients in the stomach and intestine.
What the importance of intrinsic factor?
Intrinsic factor is glycoprotein that is produced by the parietal cells of the stomach.
Why do you need intrinsic factor?
Intrinsic factor or gastric intrinsic factor is a protein produced by the stomach. It is used to absorb vitamin B12 in the small intestine. When there is a deficiency of the Intrinsic factor, there is a deficiency in the absorption of B12 into the body and this leads to pernicious anemia.
What is the function of Parietal cell?
Parietal cells are found in the lining of the stomach and secrete hydrochloric acid and intrinsic factor. Hydrochloric acid helps with digestion by breaking down food and killing bacteria, while intrinsic factor is important for the absorption of vitamin B12 in the small intestine.
Which nutrient requires intrinsic factor for absorption?
Vitamin B12 requires intrinsic factor for absorption in the small intestine. Intrinsic factor is produced by the stomach and binds to vitamin B12 to facilitate its absorption in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to deficiency.
What enables absorption of b12 across small intestine wall?
Intrinsic factor, a protein produced by the stomach, is required for the absorption of vitamin B12 in the small intestine. In the small intestine, vitamin B12 binds to intrinsic factor, forming a complex that can be absorbed through the intestinal wall.
Where does the absorption of vitamin B12 occur?
The vitamin B12 is a very important nutrient; it lowers risk of stroke, heart disease, cancer, Parkinson's, and Alzheimer's disease. The vitamin begins to absorb in the mouth, in contrast to most nutrients.
A protein secreted by the stomach that is necessary for the absorption of vitamin B12?
The protein secreted by the stomach that is necessary for the absorption of vitamin B12 is called intrinsic factor. Intrinsic factor binds to vitamin B12 in the small intestine, allowing for its absorption into the bloodstream. Without intrinsic factor, vitamin B12 cannot be effectively absorbed and can lead to a deficiency.
What is the function of the intrinsic factor?
Intrinsic factor is necessary for the proper absorption of vitamin b12 which is necessary for red blood cell maturation, and therefore prevents pernicious anemia
