The colon is where fluids and salts are absorbed and extends from the cecum to the rectum. The last part of the large intestine is the rectum, which is where feces (waste material) is stored before leaving the body through the anus.

Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum. The large intestine (colon or large bowel) is about 5 feet long and about 3 inches in diameter. The colon absorbs water from wastes, creating stool. As stool enters the rectum, nerves there create the urge to defecate.

The digestion of food is completed in the small intestine, and once the food has been broken down to its simplest form, it can be absorbed across the wall of the intestine and into the blood. The end products of digestion are carried to the liver, where they are metabolized.

The small intestine (small bowel) lies between the stomach and the large intestine (large bowel) and includes the duodenum, jejunum, and ileum. The small intestine is so called because its lumen diameter is smaller than that of the large intestine, although it is longer in length than the large intestine.

The vast majority of humans who have ever lived share the same fate after death: decomposition. Unless your body is frozen, cremated, or otherwise destroyed after you die, it will inevitably be consumed by bacteria, insects, and animals that recycle your organic substances into new forms of life.

The food that remains undigested and unabsorbed passes into the large intestine. Absorption of the majority of nutrients takes place in the jejunum, with the following notable exceptions: Iron is absorbed in the duodenum. Vitamin B12 and bile salts are absorbed in the terminal ileum.

When a twin dies after the embryonic period of gestation, the water within the twin's tissues, the amniotic fluid, and the placental tissue may be reabsorbed. This results in the flattening of the deceased twin from the pressure of the surviving twin.
