Digestive System (Medical Entrance)

Salivary amylase is responsible for breaking starch into polypeptides. The enzyme works best at pH 6.9. At this level, it is slightly acidic in nature.

It is a part of the large intestine and does not produce any enzyme. It only produces mucus.

Cystic duct connects gall bladder to the common hepatic duct that arises from the liver. Cystic and common hepatic ducts together form the common bile duct.

It is a hormone secreted from the wall of stomach. It is responsible for the stimulation of gastric gland to secrete HCl.

It is the largest salivary gland present in front of the ears and is connected to Stenson's duct.

Paneth cells are present in crypts of Leiberkuhn. They are responsible for the secretion of lysozyme.

Mucosa is the innermost layer of the wall of the alimentary canal which is devoid of circular and longitudinal muscles. Instead, it consists of glands responsible for the secretion of mucus and other enzymes.
