the digestive juices in the digestive tract include

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..

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 the milk pro..

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

. 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..

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..

A well developed digestive system which can take care of the energy requirements of the animal is present. It consists of an alimentary canal and associated structures. The buccal cavity contains teeth, which are of three different types : incisors, premolars and molars. Canines are absen..

Digestive System in Cockroach (Invertebrates) - Nutrition in cockroach is holozoic and it is an omnivore, feeding on different kinds of organic matter. It takes in pieces of food and has to grind them before digesting them. Thus its mouth parts are modified accordingly for chewi..
