Types of Blood Vessels
Blood vessels are classified into three main types: arteries, veins, and capillaries.
Arteries
Arteries are blood vessels that carry oxygen-rich blood from the heart to the rest of the body. They have thick, muscular walls which helps them to withstand the high pressure generated by the pumping action of the heart. Arteries develop into branches in the form of smaller vessels known as arterioles , which eventually divide into capillaries.
Veins
Veins are blood vessels that transport oxygen-depleted blood from the body back to the heart. As compared to arteries, veins have thinner walls and lower pressure. They c ontain valves that prevent the backward flow of blood. This facilitates its return to the heart, especially from areas distant from it.
Capillaries
Capillaries are tiny, thin-walled vessels that join arteries and veins. Their major role is to facilitate the exchange of gases, nutrients, and waste products between the blood and the other surrounding tissues. Capillary walls as compared to others are thinner in such a way that substances can easily diffuse across them.
What are Blood Vessels?
Blood Vessels are the components of the circulatory system through which the blood circulates in the body. The function of blood vessels is to deliver oxygen, nutrients, and essential substances to every cell in the body. Blood vessels create a complex network throughout the body, allowing for a continuous flow of blood from the heart to all areas and back again.
There are three major types of blood vessels. Understanding the structure of blood vessels is essential for grasping human physiology and the occurrence of common blood vessel disorders. It is known that the major function of blood vessels is to carry blood but it is essential to know the difference between the artery, vein, and capillaries; which are the different types of blood vessels.
