Homeostasis | Is the tendency towards a relatively stable equilibrium between independent elements especially as maintained by physiological processes. |
Digestive tract | to digest or break down foods that are taken into the body. The digestive process mechanically and chemically breaks down food so it can be absorbed into the body to nourish cells and provide energy. |
Digestive Tract Continued | Long hollow organs have smooth muscle fibers running in circular fibers contract and enable the food to move from one organ to the next. This function is called peristalsis. |
Salivary Glands | the salivary gland secrete saliva and enzymes chemical process that aids in digestion. Salivary amylase begins to change starch to maltose. |
Esophagus | A long straight tube about ten inches long that arises from the pharynx passes through the diaphragm and continues into the stomach the muscular walls of the esophagus move food into the stomach by peristalsis. |
Liver | Produces bile salts bile secreted into the duodenum fats is emulsified and absorbed by the intestines. |
Pancreas | produces the hormone insulin. It is essential for the use by the body tissue. Enzymes in the liver amylase breaks down starch lipase breaks down fats pancreatic proteases break down proteins. |
Small Intestine | Middle to third of the small intestine about seven half feel long Vigorous peristaltic move the fluid contents to the ileum. Ileum last approximate 12 feet. |
Large Intestine | five feet long receives digestive products from the small intestine. absorbs water and some other nutrients and collects food residue for excretion. Divided into the cecum, appendix, ascending colon, transverse colon, descending colon. |
