What are the 3 types of blood vesseles?

Answer 1

The three types of blood vessels are:

1. Arteries

2. Veins

3. Capillaries (small blood vessels in the tissues)
They are:

(1) Arteries - These are the blood vessels that carry blood away from the heart. They generally carry oxygenated blood except the pulmonary artery.

(2) Veins - These are the blood vessels that carry blood towards the heart. They generally carry de oxygenated blood except the pulmonary vein.

(3) Capillaries - They generally form a capillary network through which substances are exchanged between the blood and tissues. Capillaries carry blood from arterioles (branches of artery) to venoules (branches of vein).

Answer 2

Blood vessels could be divided into three types based on their basic functions: arteries, capillaries, and veins. Arteries(and their smaller branches known as arterioles) are responsible for carrying blood from the heart out to the tissues. They have thick, muscular walls that contract to maintain the body's blood pressure. Capillaries are the blood vessels where nutrient and gas exchange takes place. They are so small that the red blood cells must pass through them one-by-one. Their walls are so thin that gas, nutrients, and waste products can diffuse directly across the capillary wall. In fact, their walls are only one single cell thick. Veins (and their smaller contributing branches known as venules) are responsible for carrying blood from the tissues back to the heart. They have thin, non-muscular walls, and ensure that blood flows in the proper direction by using a large number of valves, which only allow the blood to flow in one direction.

Answer 3

The three types of blood vessels in the circulatory system are arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart, veins carry oxygen-poor blood back to the heart, and capillaries are tiny blood vessels that facilitate the exchange of nutrients and waste products between the blood and tissues.
