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.
Liver produces bile which is necessary for food digestion in the small intestine. Gallbladder. The gallbladder stores the bile produced by the liver. When food enters the digestive tract, bile is released into the small intestine from the gallbladder.Pancreas. Pancreas is another gland that helps in the digestion of food.hewing prepares the food for travelling through the digestive tract. This is the first mechanical process that the food undergoes once it enters the body. During chewing, the food is mixed with saliva produced by the salivary glands.
