digestive juices and enzymes

Gastric Juice - It is secreted by the secretory glands of the stomach wall. It is highly acidic as it contains hydrochloric acid (HCl). It also contains enzymes like pepsin and renin. Both act on proteins. However, renin is present only in young children. It digests th..

Gastric juice - It is secreted by the secretory glands of the stomach wall. They are called the gastric glands. The gastric glands are formed by the infoldings of the epithelium and open into the lumen through the gastric pits. There are two types of cells that line the gastric glands - p..

Breaking down food into simpler forms is called digestion. Digestion is both mechanical and chemical . In mechanical digestion, food is physically broken down into smaller particles by processes such as chewing. Chemical digestion makes use of certain che..

Digestion is defined as the process by which complex food molecules are broken down into simpler molecules, so that they can be absorbed by the body. Digestion is mechanical and chemical . In mechanical digestion, food is physically broken down into smaller particl..

. It then coagulates into calcium paracaseinate. The bolus thus partially digested is now called the chyme. Chyme is then passed into the small intestine, the opening of which is guarded by the pyloric sphincter. The first portion of the small intestine, the duodenum gets the pancreatic a..

. The food then moves into the stomach. The opening is controlled by the cardiac sphincter which is a muscular ring. The stomach opens only in response to swallowing. Here the proteins are broken down into proteoses and peptones by the action of pepsin and the soluble milk protein caesinogen is deg..

. The opening is controlled by the cardiac sphincter which is a muscular ring. The stomach opens only in response to swallowing. Here the proteins are broken down into proteoses and peptones by the action of pepsin and the soluble milk protein caesinogen is degraded into insoluble casein in childre..

Digestion starts in the mouth with the mandibles and the maxillae chewing the food. It is also acted upon by the salivary carbohydrases which partially digests the food. The food is then swallowed with the help of lubrication provided by the salivary juice. The food..
