Introduction to common knowledge of cardiovascular diseases

Our body around the blood vessels, these vessels will be transported we need the material to the body, and the cardiovascular system occupies the largest proportion in the us all the vascular system, I believe we must be very familiar with this knowledge, so the cardiovascular disease has tremendous harm to the health of our body. Here is a small series for everyone to explain what is cardiovascular disease, and I hope it will help everyone.
The cardiovascular system has many blood vessels that carry a wide variety of substances into every cell of your body. In these substances there is oxygen, fuel (glucose), building materials (amino acids). Vitamins and minerals. Tiny blood vessels called capillaries absorb oxygen in the lungs and emit carbon dioxide, so that our blood gets oxygen, and at the same time, carbon dioxide in the lungs is exhaled by us. These vessels extend into the heart and the heart pumps blood into cells throughout the body. At each cell, the blood vessel forms a capillary network that transports oxygen and other nutrients to the cell and takes away metabolic waste from the cell. Oxygen and glucose are essential substances for the cells of the body to produce energy, while metabolic waste in cells refers to carbon dioxide and water.
The blood vessels that supply nutrients and oxygen to the cells are called arteries, and the blood vessels that take away waste and carbon dioxide from the cells are called veins. The arterial blood is redder than the venous blood because the substance that carries oxygen in the arterial blood is hemoglobin, which contains iron. The pressure in the artery is greater than that in the vein. Just as all blood flows back from the cell to the heart, all the blood passes through the kidneys. There, metabolic waste is cleared of blood vessels, converted into urine, and stored in the bladder.
In fact, the name "heart disease" is incorrect. The main life-threatening disease is arterial disease. Year after year, deposits begin to form on the walls of the arterial walls. They are called arterial plaques or atheroma. The word "atheroma" comes from the word "porridge" in greek. The reason for this is that the deposits in the arteries are very similar to the thick ones. This phenomenon of arterial deposition is called atherosclerosis, and it occurs only in certain parts of the body. With atherosclerosis, the blood is more viscous than normal blood and contains clots. Under their combined action, the arteries clog up and cause blood flow to stop. If this occurs in the arteries that supply the heart, the heart of the donor, who is responsible for the provision, will die of lack of oxygen. This is called myocardial infarction or heart disease. Before this happens, many people are diagnosed with angina - a coronary artery that is partly blocked by oxygen and glucose supplied to the heart, causing oxygen in the heart and causing pain in the chest. This usually happens when we are under exertion or under pressure.
If blockages occur in the brain, then part of the brain dies. This is stroke. The arteries in our brain are very fragile. Sometimes a stroke is not blocked, but this is the artery rupture, cerebral hemorrhage. If the obstruction occurred in the leg, will cause leg pain, this is a thrombosis (a thrombosis is a blood clot.). When the artery of the body surface is blocked, it will cause the body surface circulation disorder in the hand or the leg.
Believe that after a small series of interpretation, with adequate recognition of our understanding of the cardiovascular disease, so small to be here to remind you, the usual time must pay attention to the protection of this, only in this way can we stay away from the disease, overall cardiovascular disease is not terrible, as long as we pay attention to their diet, can greet each day with a healthy body!
