The statement that is correct for most veins in the human body is " they have valves".
BLOOD VESSELS:
- Blood vessels are a part of the components that make up the circulatory system. They function to convey blood from one location to the other.
There are three types of blood vessels namely: veins, arteries and capillaries.
- Veins: Veins are vessels that convey deoxygenated blood back to the heart (except pulmonary veins). Veins are characterized by the possession of valves that help prevent the backward flow of blood.
- Arteries: Arteries are vessels that carry oxygenated blood away from the heart.
- Capillaries: Capillaries are tiny vessels that connect arteries and veins.
- Hence, the statement that is correct for most veins in the human body is " they have valves".
