Dorsal metatarsal arteries
Arteries are blood vessels that convey blood away from the heart. Arteries can be divided into systematic arteries, which carry blood from the heart to the entire body, and pulmonary arteries, which are responsible for carrying blood from the heart to the lungs. Apart from the pulmonary and umbilical arteries, the blood in the arteries is oxygenated. Systematic arteries are classified as elastic and muscular depending on their composition. The larger arteries are generally elastic and the smaller ones tend to be muscular. Systematic arteries carry blood to the arterioles, which are the smallest type of arteries and are responsible for delivering blood to the capillaries. Arterioles also regulate blood pressure by the muscular contraction of their walls. Capillaries are tiny blood vessels in which gasses and nutrients are exchanged. Arteries are subject to atherosclerosis, which occurs when plaque build ups inside the artery walls as a result of cholesterol, smoking, blood sugar, etc. This can lead to a heart attack or a stroke, two of the leading causes of death in developed countries.
