Human Digestive System

The digestion of food starts from mouth, where the food is chewed and is mixed with saliva. Saliva contains an enzyme (salivary amylase) which converts starch present in the food into simple carbohydrates. 

Glycogen is the primary storage form of glucose in animals and is stored primarily in the liver and skeletal muscles.

Bile is produced by the liver but is stored and concentrated in the gall bladder before being released into the small intestine to aid digestion. Therefore, the gall bladder is the collection site.

Cholecystokinin and pancreozymin are two hormones that stimulate the secretion of pancreatic juice. Cholecystokinin causes contraction of the gall bladder and discharges the bile into the duodenum. Pancreozymin also stimulates the pancreas to secrete insulin and glucagon.

The liver produces bile, which emulsifies fats, but bile does not contain digestive enzymes. The other listed organs all secrete specific enzymes for digestion.

The pancreas is a dual-function organ. It acts as an exocrine gland by secreting digestive enzymes into the small intestine and as an endocrine gland by secreting hormones like insulin and glucagon into the bloodstream.

Correct. This protein is as sweet as sugar and is used as a low calorie swetner

 Osmotrophy is the uptake of dissolved organic compounds by osmosis for nutrition, digestion occurs outside the body of the organism.

Bile is produced by the liver and stored in the gallbladder. It contains bile salts that emulsify fats, aiding digestion, but it does not contain digestive enzymes itself.

Alliinase is responsible for catalysing chemical reactions that produce the volatile chemicals that give odours and tear-inducing properties.

Ecarin is derived from the venom of the Indian saw-scaled viper.

This enzyme participates in bile acid biosynthesis.

This is a significant brush border enzyme.

The stomach has a priority to destroy the bacteria and viruses using its highly acidic environment.
