A carbohydrate splitting enzyme is secreted by
-
Liver
-
Zymogen cells of gastric glands
-
Spleen
-
Crypts of Lieberkuhn
While the chyme is present within the small intestine, glands within this structure begin to secrete different types of digestive enzymes, called carbohydrases (amylase, proteases, and lipases or fat splitting enzymes). The glands responsible for these enzymatic secretions are found in the mucosal layer of the small intestine, called the crypts of Lieberkuhn.
Crypts of lieberkuhn are present in
-
Intestine
-
Stomach
-
Oesophagus
-
All of the above
An intestinal gland (crypts of Lieberkuhn) is a gland found in the epithelial lining of the small intestine and colon. The glands are named after German anatomist J. N. Lieberkuhn.
Crypts of Lieber kuhn are present in ___________.
-
Intestine
-
Stomach
-
Oesophagus

Which of the following gland is partly exocrine and partly exocrine?
-
Pituitary
-
Thyroid
-
Pancreas
-
Hypothalamus
Heparin is synthesised in
-
Kidney
-
Salivary glands
-
Pancreas
-
Liver
Heparin is an anticoagulant formed in the liver and mast cells. It is found in blood and connective tissues. It belongs to a class of mucopolysaccharides and helps to prevent blood clots in arteries and veins. It is an anticoagulant that prevents the formation of blood clots. It is also used before surgery to reduce the risk of blood clots. It helps the blood to flow smoothly in the body by making a certain natural substance in the body work better.
In human beings, sphincter of oddi is situated in
-
Common bile duct
-
Ampulla of vater
-
Main pancreatic duct
-
Common hepatic duct
The sphincter of Oddi, abbreviated as SO, is a muscular valve that controls the flow of digestive juices through the ampulla of Vater into the second part of the duodenum. The sphincter of Oddi is relaxed by the hormone cholecystokinin via vasoactive intestinal peptide.
Stool of a person contain whitish grey colour due to malfunction of which type of organ : -
-
Pancrease
-
Spleen
-
Kidney
-
Liver
The pancreas produces?
-
Three digestive enzymes and one hormone
-
Three types of digestive enzymes and two hormones
-
Two digestive enzymes and one hormone
-
Only digestive enzyme and no hormone
- Proteases: to digest proteins.
- Lipase: to break down fats.
- Amylase: for the digestion of carbohydrates.
- Insulin: This hormone regulates blood glucose by allowing many of your body’s cells to absorb and use glucose. In turn, this drops blood glucose levels.
- Glucagon: Glucagon helps insulin maintain normal blood glucose by working in the opposite way of insulin. It stimulates your cells to release glucose, and this raises your blood glucose levels.
Kupffer's cells of liver are an example of ________________.
-
Anatomical barrier
-
Inflammatory barrier
-
Physiological barrier
-
none of the above
Kupffer cells are also known as stellate macrophages (star-shaped) located in the liver, lining the walls of the sinusoids. They form part of the mononuclear phagocyte system. This means that they are a part of the first line of defense (inflammatory barrier) of the body and are involved in engulfing any invading pathogen (virus, bacteria, etc.) and destroy them.
Simple absorbable forms are produced by secretions of all except
-
Hepatocytes
-
Enterocytes
-
Parietal cells

Oxyntic cells
