What is the anal channel?
The anal channel is an area between the rectum and the rectum, and is a place where the large intestine and technically digestive system end. It is approximately 1 inch (2.5 cm) to 1.5 inches (4 cm) and is surrounded by a sphincter, a muscle that controls the opening and closure of the channel. The slope is what the intestinal movements drive. Zona Colonouris occupies the upper half of the anal canal and is lined with the same tissue as the small intestine, the stomach and the large intestine, while the lower half of the canal contains Zona Hemorigic and Zona Cutane. Both lower parts contain different tissues than Zona colonouris, including tissue, which is usually observed in more exposed skin, such as lips. It surrounds the lower half of the channel and has two aspects: inner sphincter and outer sphindter. The inner sphincter, part near the large intestine, is involuntary and cannot be consciously inspected and the external sphincter is voluntary, which means that it can be intentionally opened or closed. Sphinter can hold the feces or leave them through the rectum.
One of the problems that is commonly observed in the anal channel is hemorrhoids. Hemorrhoids are enlarged veins that can cause itching and discomfort. In some cases, they can fall out or upload from the channel to the rectum. Often bleeds in more serious cases. When the feces are in the channel, it can cause more discomfort, even with small hemorrhoids. Fortunately, hemorrhoids can be treated with drugs or surgery.
Other problems may arise with the anal channel, including cracks, abscesses and fistulas. Trumes are small tears in the channel and can be very painful and closing and expanding the challenges deteriorates the crack. Abscesses are infected with growth and can easily arise from fistula. Fistula is an abnormal tract or channel that is formed in the skin due to infection.
rectal and anal channel cancer is relatively rare and represents about 2% of all gastrointestinal cancers. Is much less common than cancer tlThe appointment of the intestine, which has about 100 times higher degree of death. Anal cancer occurs equally in men and women.
Fortunately, the anal channel is easily accessible because it is so close to the outside of the body. As a result, changes or problems in the area are easy to see. Because the anal channel is easily accessible, treatment, especially surgery, is relatively easy. Yet approximately 600 people die of anal cancer in the US a year.
