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.
Fat digestion begins in your mouth and protein digestion begins in your stomach. The most extensive breakdown of these nutrients, however, occurs in your small intestine, with assistance from your pancreas and gallbladder. Different groups of chemicals are responsible for the digestion lipids and proteins.
