Chyme will go through the small intestine‚ where 95% of absorption of nutrients occurs‚ through the large intestine‚ and are excreted duringdefecation.[1] Other organisms use different mechanisms to digest food.

to stomach. Gastric motility is also a key factor in stomach specific drug delivery. Brief knowledge of motility is necessary for developing a retentive form of drug. Gastric motility differs in fasting and fed states. In fasting states‚ an Inter-digestive myoelectric motor complex (IMMC)‚ a 2 hr. cycle of peristalsis is generated which progresses to ileocecal junction. It consists of 4 phases: a) Phase I: also called quiescent period with rare low amplitude contractions‚ lasting for 30-60 mins. b)

muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food. The lining of the stomach secretes hydrochloric acids and enzymes that break down the food so that it can continue on its journey through the digestive system. As it secretes acid and enzymes‚ the stomach muscles contract in a process called peristalsis to mix the food with the acid and enzymes. The acid also works to kill harmful microbes that may have made their way into the body along with food

Bacteria are found in humans from birth‚ where they feed and continue to develop. In the digestive tract they feed from decaying food matter‚ which results in digestion‚ and providing nutrients to the host. Other bacteria host on inanimate objects and decompose things that if left for a while could be unhealthy for a particular environment. The

The human respiratory system is adapted to allow air to pass in and out of the body and also for efficient gas exchange to occur. The respiratory system includes air passages‚ pulmonary vessels‚ the lungs‚ and breathing muscles. Most of the organs of the respiratory system help to distribute air‚ but only the tiny alveoli and the alveolar ducts are responsible for the gas exchange. Mouth - The mouth is the secondary exterior opening for the respiratory system. Most commonly‚ the majority of respiration

How does food move through the body? Food passes through the GI tract‚ and mixes with digestive juices. Eventually‚ it causes large molecules of food to break down into smaller molecules. Then‚ the body absorbs the smaller molecules through the walls of the small intestine into the bloodstream The bloodstream then delivers the small molecules to the rest of the body. After this‚ the food continues into the large intestine‚ and out your body. What happens during the chemical digestion in the
