If a blood clot forms, it can stop the blood flow. This can cause a heart attack or stroke. A heart attack occurs when the blood flow to a part of the heart is blocked by a blood clot. If this clot cuts off the blood flow completely, the part of the heart muscle supplied by that artery begins to die.
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
Digestion is the process by which food is broken down into absorbable nutrients in your body. Digestion involves your mouth, esophagus, stomach, small intestine and large intestine, as well as accessory organs, which include the pancreas, liver and gallbladder.at digestion, which requires a digestive fluid called bile, begins in the small intestine. Bile is a digestive fluid that consists of cholesterol, bile acids, water, potassium, sodium and bilirubin -- a waste product formed from the breakdown of red blood cells.
