absorption into the blood system. Bile also lubricates the digestive tract.

Gall Bladder: It is embedded in the liver and acts as a store house for the bile, releasing it as needed. It emulsifies the fat making it easy to digest.

Pancreas: Produces digestive juices and enzymes. Produces insulin which controls the glucose (energy food) level in the blood (in case of diabetics)

Small Intestine: First part of the small intestine is duodenum where the digestion of food is brought near completion. It propels the food along the digestive tract.

Large Intestine: It consists of ascending, transverse and descending colon (including sigmoid and rectum). It absorbs water and electrolytes from the waste material and stores fecal matter until it can be expelled.

Ileocecal valve: It's a passage way between the small and large intestine. Its principal function is to prevent back flow of fecal contents from the colon into the small intestine. It is responsible for the control of mucus (e.g. sinus and lung problems).

Urinary System

It is the chief disposal unit of the body.

Kidneys: are the chief organ of the urinary system, regulating fluid in the body and purifying the blood. Filtration in the kidneys begins with the straining of fluid from the blood. They regulate the acid/alkaline balance the body's fluids, stimulate the production of RBC when needed, watch over the amount of salt and other substances in the blood.

Ureter tubes: are the link between the kidneys and the bladder. It's a passage way through which urine passes after having been produced in the kidneys.

Bladder: acts as a reservoir. When it is full of urine, nerve fibres react to initiate urination.
