There are three types of blood vessels in the human body:

• Number 1

Arteries: These are blood vessels that carry blood away from the heart to various parts of the body. They have thick and muscular walls that can withstand the high pressure of blood pumped by the heart.

• Number 2

Veins: These are blood vessels that carry blood back to the heart from different parts of the body. They have thinner walls compared to arteries and have valves to prevent backflow of blood.

• Number 3

Capillaries: These are the smallest blood vessels in the body and connect the arterioles (smaller arteries) to the venules (smaller veins). They are responsible for the exchange of oxygen, nutrients, and waste products between the blood and body tissues.
