Human digestive system - How it works!
The human digestive system is very complex and has evolved
over millions of years. It basically consists of the rectum, the
large intestine, the small intestine and the pancreas. The
stomach is composed of a similar structure to the esophagus
about one to two liters of gastric juice are produced per day
food also contains bacteria that can damage the body,vitamin
B12 helps keep the body 's nerve and blood cells healthy and
helps make DNA.It also contains gastric lipase, an acid resistant
enzyme for fat digestion in the small intestine, the intrinsic
factor is needed to absorb vitamin B12.The small intestine
consists of three sections, duodenum,, jejunum, ileum and
ileum. Each villus contains blood capillaries and a lymphatic
capillary called lacteal.The ileum absorbs electrolytes such as
calcium for building bones, hair, and teeth.The small intestine is
connected to the large intestine via the bauhin's valve.It opens
when chyme is to pass from the small intestine to large
intestine. The large intestine has an estimated 100 billion
bacteria inside. These bacteria are an important part of the
immune system by killing harmful germs.
