When a person has arteriosclerosis, the walls of their arteries get harder, stiffer, and less stretchy. If an artery in the brain starts bleeding, the bleeding can cause a stroke.Īrteriosclerosis and atherosclerosis ĭiagram showing the effects of atherosclerosis on an artery. For example, if a person's femoral artery is cut, they can bleed to death. Arterial bleeding can happen very quickly. Because of this, an arterial bleed - bleeding from an artery - can be a medical emergency, especially if the artery is big. Unlike the veins, the arteries are always stretching and then squeezing to push blood through them to the body. Problems with arteries Arterial bleeding īecause the heart pumps blood right into the arteries, the arteries are under a lot of pressure. This cycle continues, over and over again. Īfter picking up more oxygen, the blood travels back to the left side of the heart and is pumped out to the body by the aorta. In the lungs, the blood can pick up more oxygen. The pulmonary artery carries this blood from the heart's right ventricle to the lungs. The veins' job is to carry the deoxygenated blood back to the right side of the heart. This blood then travels through capillaries to get from the arteries to the veins. The blood in these arteries becomes deoxygenated - it does not have much oxygen left in it. The body uses the oxygen carried in the other arteries to make energy.
