The human gut is a long, coiled tube that starts at the mouth and ends at the anus. Along its length are many different types of bacteria, which help to break down food and extract nutrients. The gut also contains immune cells, which help to protect the body from infection.
The gut is divided into three main parts: the small intestine, the large intestine, and the rectum. The small intestine is where most of the digestion and absorption of food takes place. The large intestine absorbs water and electrolytes from food, and also houses bacteria that help to break down undigested material. The rectum stores feces until they are ready to be eliminated from the body.
There are many different disorders that can affect the gut, including infections, inflammatory diseases, malabsorption syndromes, and tumors. Treatment for these conditions varies depending on the specific disorder.
