Where is the intrinsic factor produced?

Intrinsic factor is a protein that helps your intestines absorb vitamin B12. It is made by cells in the stomach lining.

Which of the following produces intrinsic factor quizlet?

Intrinsic Factor – Secreted from Parietal Cells (B12 Abs.) Pepsinogen – Secreted from Chief Cells in body of stomach (Digest Prot.)

What cells produce intrinsic factors quizlet?

also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of vitamin B12 later on in the ileum of the small intestine.

Which of the following cells produce gastric intrinsic factor quizlet?

Glandular mucous cells secrete mucus, the chief cells secrete enzymes, mainly pepsinogen, and the parietal cells produce hydrochloric acid and the intrinsic factor.

What is intrinsic factor quizlet?

Intrinsic factors. a substance by the stomach that enables the body to absorb vitamin B12 (a glycoprotein) B12. needed for red blood cells to grow. Anemia.

Where is intrinsic factor secreted What is its function?

Intrinsic factor is secreted by parietal cells of the gastric glands in the stomach, where it binds with the vitamin. Thus bound, intrinsic factor protects vitamin B12 from digestion as it passes through the gastrointestinal tract and facilitates the vitamin’s absorption in the ileum of the small intestine.

Which of the following cells of the stomach produce intrinsic and hydrochloric acid?

A parietal cell. Parietal cells (also known as oxyntic cells) are epithelial cells in the stomach that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and body regions of the stomach.

Which of the following cells produce HCl quizlet?

The cheif cells produce pepsinogen, which is the inactive pepsin enzyme and the parietal cells secrete HCl needed to activate pepsinogen.

What is the purpose of intrinsic factor in gastric juice quizlet?

Intrinsic factor in gastric juice: Necessary for the absorption of vitamin B12 in the terminal ileum.

Do parietal cells produce intrinsic factor and quizlet?

Parietal cells secrete intrinsic factor and it functions as a carrier molecule which binds vitamin B12 so that it can be absorbed by the intestine. … Chief cells, also known as Peptic Cells, are found in the glandular region of gastric glands which is found in the lamina propria of mucosa layer.

What is an example of an intrinsic factor?

Genetic intrinsic factors are hard coded into a person’s DNA and include biological relationship, race, and ethnicity. … These factors include a person’s age, organ function (e.g., liver, kidney, cardiovascular), and co-morbid diseases.

What is Castle’s intrinsic factor?

Intrinsic factor, a glycoprotein produced by the parietal cells of the stomach, which is necessary for the absorption of vitamin B. 12.

Which digestive organ produces pepsin and intrinsic factors quizlet?

Stomach – Bag for food storage. When empty, the stomach is collapsed and has large impermanent folds called Rugae. Produces HCl acid and pepsin, which starts the digestion of proteins.

What cells produce hydrochloric acid HCl?

Parietal cells produce HCl by secreting hydrogen and chloride ions. When pepsinogen and hydrochloric acid exist together in the gastric juice, pepsin takes its active form.

What is the function of intrinsic factor secreted by parietal cells of the stomach quizlet?

Parietal cells produce hydrochloric acid and a substance called intrinsic factor, which is needed for adequate intestinal absorption of vitamin B12.

Which of the following is an accessory organ in the digestive system?

Associated with the alimentary tract are the following accessory organs: salivary glands, liver, gallbladder, and pancreas.

Which cell of the gastric glands produces Pepsinogen?

gastric chief cells
Pepsinogens are synthesized and secreted primarily by the gastric chief cells of the human stomach before being converted into the proteolytic enzyme pepsin, which is crucial for digestive processes in the stomach.

Which organ contains villi?

(d) Large intestine. The lining of the small intestine contains villi – finger like projections.
