Which nutrient requires intrinsic factor for absorption?
b12
What enables absorption of b12 across small intestine wall?
Intrinsic factor, which is made in the stomach.
Excessive bleeding caused by congenital lack of factor VII or IX?
A lack of factor VIII is hemophilia A, and a lack in factor IX is hemophilia B. They can cause excessive bleeding because the person is unable to clot.
Does lack of insulin result in high blood sugar levels?
It can.
Are they three clotting pathways?
The coagulation cascade is classically divided into three pathways. The tissue factor (formerly known as the extrinsic) and the contact activation (formerly known as the intrinsic) pathways both activate the final common pathway of factor X, thrombin and fibrin.
Inadequate intrinsic factor is associated with?
due to lack of b12 No HCl and intrinsic factor = pernicious anemia
Pernicious anemia results from a combination of lack of intrinsic factor and?
atropic gastritis
What results from the hereditary lack of intrinsic factor?
Pernicious anemia (vitamin B 12 deficiency)
Aids in absorption of vitamin b12?
It is called intrinsic factor, which enables the absorption of B12. Intrinsic factor is found in the parietal cells (mucosa cells) of the stomach lining.
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 important function of the intrinsic factor found in the stomach?
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.
Lack of intrinsic factor?
DefinitionIntrinsic factor is a natural substance normally found in the stomach. You need this substance to absorb vitamin B12 from foods.A lack of intrinsic factor leads to pernicious anemia and vitamin B12 deficiency, which can cause anemia and brain and nervous system (neurological) problems.Alternative NamesIntrinsic factor - lack ofCauses, incidence, and risk factorsBabies that are born without intrinsic factor cannot properly absorb vitamin B12 starting around age 6 months. Children who have the juvenile type of lack of intrinsic factor tend to show signs and symptoms after age 10.Older adults get pernicious anemia, which is caused by a lack of intrinsic factor production. This is usually due to an autoimmune disease that causes the stomach lining to waste away (atrophy). The stomach lining is where intrinsic factor is usually made.ReferencesAntony AC.

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.
What is perniciousness?
This is anaemia (lowered blood haemoglobin) due to a lack of vitamin B12 absorbed from the intestinal tract, due to a lack of intrinsic factor usually. This can be due to auto antibodies against the cells that produce intrinsic factor, stomach ulcers crowding out the cells that produce intrinsic factor, a hereditary lack of intrinsic factor or the after effects of surgery, illness or fish tapeworm. This gives a macrocytic anaemia. Pernicious anemia is an autoimmune disease that renders the person unable to absorb sufficient Vitamin B-12. Eventually the person becomes Vitamin B-12 deficient and must be treated. Prior to the availability of treatment persons died from the disease, hence the name pernicious. It is critical that treatment be obtained as soon as possible. You can find more information at the following website: www.pernicious-anaemia-society.org
