Body Organs - Kidney, Small Intestine, Large Intestine Functions Defined

Kidney: These are bean shaped paired organs, situated at the rear of the abdominal cavity. The main functions of the kidneys include maintaining whole body homeostasis where the overall condition of the body is regulated by monitoring and correcting various factors like pH levels and temperature of the body.


It also carries out the important function of filtering and excreting metabolic wastes in the form of urine which may consist of nitrogenous wastes like uric acid, nucleic acid etc.


Small Intestine: The small intestine is one of the members of the gastrointestinal tract and is primarily responsible for the absorption

of nutrients from the partially digested food received from the stomach as chyme.


The enzymes used for processing and absorption of the chyme is basically acquired from the pancreas, which secretes most of the digestive juices and introduces them into the small intestine through the pancreatic duct. The


pancreatic juices are stimulated by the hormone cholecystokinin produced in the small intestine, which in turn is secreted in response to the various nutrients present in the food.


Large Intestine: The large intestine is the concluding section of the digestive system and is fundamentally includes parts like the cecum, colon, rectum, and anal canal, orderly.
The main function of the large intestine is to extract water from the final indigestible food and convert it into fecal matter.
Precisely, here the colonic bacteria in the colon starts the process of absorbing useful vitamines like vitamin K, B12, thiamine, riboflavin etc. from the remaining indigestible material until it's completely converted to waste material in the form of feces. The fecal matter is stored in the rectum until it's finally thrown away through defecation.
