What are the functions of salivary glands gastric glands liver and pancreas?
Answers
Salivary glands: The salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist. It also helps break down carbohydrates (with salivary amylase, formerly known as ptyalin) and lubricates the passage of food down from the pharynx to the esophagus to the stomach.
Gastric glands : are found in the fundus and body of the stomach. They are simple almost straight tubes, two or more of which open into a single duct. Oxyntic means acid-secreting and they secrete hydrochloric acid (HCl) and intrinsic factor.
Liver: detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions.
Pancreas: The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar.
salivary gland - secretes saliva which contains salivary amylase. it converts carbohydrates in simple sugar (glucose ).
gastric gland -secretes gastric juice which consist of hcl, pepsin and mucus
hcl
- kills harmful microbes that enter along with food
-stops the action of salivary amylase
- provides acidic medium for the enzyme pepsin
pepsin
-converts protein into peptones
mucus
- it protects the inner lining of the stomach from getting corroded by harmful hcl
pancreas- secretes pancreatic juice which consists 3 pancreatic enzymes
pancreatic amylase converts glucose into glucagon
pancreatic trypsin converts peptones into ammino acid
pancreatic lypase converts emulsified day into fatty acids
