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.
Best Answer: All digestion begins in the mouth and stomach where food is broken into small pieces. Proteins are broken down in the stomach by the enzyme protease (pepsin) and is digested further in the small intestines where the pancreas has injected more protease. Lipid digestion advances in the small intestines.Lipids are broken down by bile which is produced in the liver, stored in the gall bladder and injected into the small intestines. The pancreas also injects the enzyme lipase which breaks down lipids. Carbohydrates are also thoroughly digested in the intestines.ipid digestion advances in the small intestines.
