An IED is a bomb fabricated in an improvised manner incorporating destructive, lethal, noxious, pyrotechnic, or incendiary chemicals and designed to destroy or incapacitate personnel or vehicles. In some cases, IEDs are used to distract, disrupt, or delay an opposing force, facilitating another type of attack.
Small Intestine. The small intestine is a winding, tightly folded tube about 20 ft (6 m) long in adults. It connects to the stomach on the top end and to the large intestine (colon) on the bottom end. Most of the food a person consumes is digested and absorbed in the small intestine. The lining of the small intestine has tiny, finger-shaped tissues (villi).
Small Intestine: Site of Nutrient Absorption. The small intestine, which is approximately 10 feet long, is the site of most nutrient absorption. The inside surface of this organ contains numerous folds, covered by very thin, long projections on the inside of the intestinal wall called villi.
