Mechanisms of action of the stomach

– The stomach encapsulates food with a mixture of acid and digestive enzymes to help break down food further, and the mucus layer protects the lining of the stomach from damage by acid, the lower part of the stomach is able to contract, helping to speed up the process, when food is broken enough, The stomach releases its contents into the duodenum.

– The intestine extends from the stomach to the anus, water and nutrients are mostly absorbed in the intestine (nutrients in the small intestine and water in the large intestine), the intestine consists of 3 parts:

1 – small intestine
2
– large intestine 3 – rectum

– The length of the small intestine, also called the small intestine, is about 20 feet in diameter and one inch in diameter, absorbing most of the nutrients from the chem (a semi-liquid form of food after partially digested), the velvet tissue is lined up on the small intestine.

About the small intestine

It is classified into three parts, the duodenum is the first, and the second jejunum and ileum last part, when food enters the duodenum, the pancreas secretes enzymes to help break down fat, protein, and carbohydrates. The bladder produces the gallbladder, produced by the liver, to help further break up fat into a form that can be absorbed by the intestine.

The small intestine is lined with finger-like projections, called villi, which provide a very large area to facilitate the absorption of nutrients, including carbohydrates, proteins, and fats, into the bloodstream, and the small intestine plays a key role in regulating blood sugar levels. A number of receptor cells detect the presence of macronutrients and secrete hormones that direct the pancreas on how much insulin and glucagon should be released. The duodenum is the first part of the small intestine which is also the shortest (about 25 cm, or about 10 inches).

About the large intestine

It is about 5 feet large, and two inches in diameter, the large intestine is where most water absorption occurs, when water is absorbed, it leaves behind an undigested part of the food, known as feces, and when the stool enters the rectum, the nerves are sent In that area pulses to the brain making an urge to defecate.

Most of the large intestine is located in the abdomen, the sigmoid colon, and the rectum in the pelvic cavity. The abdominal part of the large intestine includes the cecum and the ascending, transverse and descending colon. The main function of the large intestine is the absorption of water from the stool material before disposal from the body, the colon is also home to bacteria Friendly that synthesizes vitamin K and keeps bad microbes under examination.
