Human digestive system

If fats are not absorbed in this way in the small intestine problems can arise later in the large intestine which is not equipped to absorb fats.

The taste of umami is thought to signal protein-rich food. This allows the mass of food to further mix with the digestive enzymes. This results in a much larger surface area for the action of digestive enzymes. The remaining semi-solid waste is termed feces and is removed by the coordinated contractions of the intestinal walls, termed peristalsiswhich propels the excreta forward to reach the rectum and exit via defecation from the anus.

Digestive System

The detection of saltiness and sourness enables the control of salt and acid balance. Bile produced by the liver is also used to mechanically break fats into smaller globules. Gastric juice is a variable mixture of water, hydrochloric acidelectrolytes sodium, potassium, calcium, phosphate, sulfate, and bicarbonateand organic substances mucus, pepsins, and protein.

This starts at the mouth and ends at the anuscovering a distance of about nine 9 metres. Vitamin B12 cobalaminis carried to, and through the stomach, bound to a glycoprotein secreted by the salivary glands - transcobalamin I also called haptocorrinwhich protects the acid-sensitive vitamin from the acidic stomach contents.

Taste buds are mainly on the upper surface dorsum of the tongue.

Your Digestive System

Responsible for most digestive, absorptive and secretory processes. This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat.

Bile flows from the liver through the bile ducts and into the gall bladder for storage. Pepsinogen is a precursor enzyme zymogen produced by the gastric chief cellsand gastric acid activates this to the enzyme pepsin which begins the digestion of proteins.

This allows the mass of food to further mix with the digestive enzymes.

Digestive System

Can you guess where it ends up? The lower GI starts at the pyloric sphincter of the stomach and finishes at the anus. Once in the more neutral duodenum, pancreatic enzymes break down the protective glycoprotein.

At the same time that protein is being digested, mechanical churning occurs through the action of peristalsiswaves of muscular contractions that move along the stomach wall. This sac-like organ stores bile produced by the liver and then releases it as necessary.Human Digestive System coloring page from Anatomy category.

Human Body Detectives Merrin and Pearl are at it again. Their magical ability to jump into people's bodies and explore their systems (digestive, skeletal, nervous (June ), circulatory, and immune) combines science with their fun adventures to help kids understand their anatomy and how their bodies work.

Gallery of Arvind Gupta's Fun Science Toys hosted by The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).
