There are about 0.62 miles in a kilometer.    A more exact answer:   One mile is 5,280 feet. One foot is 0.3048 meters. Therefore one  mile is 1,609.344 meters, orâ¦ 1.609344 km. Dividing 1 km by that  figure gives the answer that one km is 0.6213711 mile.
The jejunum (/dÊáµ»ËdÊuËnÉm/) is the second part of the small intestine in humans and most higher vertebrates, including mammals, reptiles, and birds. The jejunum lies between the duodenum and the ileum. The jejunum is considered to begin at the attachment of the suspensory muscle of the duodenum to the duodenum, a location called the duodenojejunal flexure. The division between the jejunum and ileum is not anatomically distinct.
The ileum follows the duodenum and jejunum and is separated from the cecum by the ileocecal valve (ICV). In humans, the ileum is about 2â4 m long, and the pH is usually between 7 and 8 (neutral or slightly alkaline).Ileum is derived from the Greek word eilein, meaning to twist up tightly..he function of the ileum is mainly to absorb vitamin B12 and bile salts and whatever products of digestion were not absorbed by the jejunum. The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface.
