The disgestive system is vital to sustain life processes. It digest food, nutrients, excretes waste generated by the body and allows organs to obtain nutrients to carry it's own processes.
It also helps hydrate the body with necessary liquids.
The digestive system of the human body can be described as a long tunnel. The process begins during chewing, when the enzyme salivary amylase begins to break down carbohydrates. Swallowing carries the food through the throat and gravity takes it down the esophagus. When it enters the stomach the food "bolus" triggers various digestive juices to be released from the stomach wall, which primarily work to break down proteins. One of these is HCl- hydrochloric acid, which is part of why excess amounts of this fluid can cause it to leak back up into the esophagus which does not have a lining that's resistant to these acids. The other major enzyme acting in the stomach is Pepsin.
The GI system is regulated and coordinated by regulatory peptides which control secretion of enzymes, electrolytes, and water as well as influencing gastric emptying, release of certain hormones and the process of intestinal absorption. The regulator peptides are gastrin, cholecystokinin (CCK), secretin, and gastric inhibitory peptide (GIP).
When the stomach contents (chyme) leave the stomach through the gastric sphincter they enter the duodenum of the small intestine. At that point there are numerous enzymes that are secreted into the small intestine from both the pancreas and the mucosa cells along the small intestine walls. One of the key enzymes released from the pancreas is Insulin, which affects the storage and release of glucose into and from the blood.
Another important component in the small intestine is bile, which arrives via a special duct from the liver. Bile is crucial for digestion and absorption of fats and fat-soluble substances such as vitamins A and D.
The small intestine is composed of different sections, each of which have different characteristics and absorb different vitamins, minerals and macronutrients. In the colon, water is reabsorbed from the matter as it is moved through the three major sections, the ascending colon, the transverse colon, and the descending colon. The waste is released through the sigmoid colon, rectum and finally the anal sphincter.
This is but a brief description, and the system is extremely complicated, including its own nervous system to oversee the movement of matter throughout. It is one of those amazing processes we tend to take for granted until something goes wrong.
The alimantry canal along with the associated glands is called digestive system
The digestive system is where the food breaks into small pieces the turn it into waste (feces)(^-^)/
It breaks down food into usable chemicals
The human body hydraulic system is more than just your digestive and circulatory system. It also your respiratory and nervous system.
The Circulitory, the digestive, and the nervous system r 3 subsytems of the human body :)
All systems in the human body directly or indirectly depend on each other. However, the digestive system mainly relies on the circulatory system and the musculatory system. The circulatory system brings enzymes and oxygen to the digestive system. The musculatory system performs peristalsis, to move the food through the digestive system.
The highest level of organization that consists of all organ systems of the body is organismal.
As Lactic acid is formed from glucose, it is produced in the stomach of the digestive system
The digestive system is different from the other human body systems because the digestive system holds food and no other human body system does also the digestive system has organs that none other human body systems have.

The human body hydraulic system is more than just your digestive and circulatory system. It also your respiratory and nervous system.
Human body systems include: the nervous system, the digestive system, the circulatory system, the immune system, the integumentary system.

the digestive system
The human digestive system is a bunch of organs that turns food into essential nutrients that are absorbed into the body. It also moves the unused waste material out of the body.
