Introduction To Digestion
Digestion is the process in which food is broken down in order for the cells to take it in. Food is too big to get through the cell membrane so chemical and mechanical digestion aids in breaking down food. In chemical digestion Amylase, and enzyme in saliva, breaks down things like starches. Mechanical digestion involve chewing and the formation of a bolus which is a bowl of food formed by the tongue. After food travels down the esophagus and into the stomach, hydrochloric acid in the stomach help break down the food even more. The food then travels to the small intestine where the villi help in absorbing nutrients which travel to ones blood stream then to the cells. The food then travels to the large intestine where excess water is absorbed.
Cellular Respiration is a process that takes place in the mitochondria of the cell. The mitochondria provides energy for the cell using glucose. ATP, adenosine tri phosphate, is produced using glucose. The last bond store a lot of energy and when broken releases energy for the cells in order for one to perform physical activity. ATP then becomes ADP and used glocose to become ATP once agian.

Atlantic Sturgeon Digestive System

Anatomy of the Atlantic Sturgeon
Sturgeons are primarily bentihic feeders. Their mouths are located on the underside of their heads and they have no teeth. For this reason their four barbels(whiskers) aid in sensing and capturing food. Atlantic Sturgeons also have a tubal shaped mouth which extends a few inches when feeding. As they swim along the bottom of the see, Atlantic Sturgeons used their barbels to search and catch food. The food travels down the esophagus and into the stomach. The acid in the stomach called HCI helps break down the food that the Sturgeon can't break down because they don't have teeth. The Muscular "gizzard" provides movement. The Pyloric Ceca which is located by the stomach and the small intestine it contains an enzyme that aid in digestion and also absorb digestion food[1]. The liver provided enzymes that aid in breaking down fat. After food passes through the small intestine, waste travels to the vent where it then leaves the body[2]. |
