How does blood flow in the body?

 

The blood moves in the body in a specific way, which does not change, and the following is the way blood flows through the body:

 

 

Veins bring blood to the right side of the heart.

 

Then the pulmonary arteries carry blood to the lungs, where it receives oxygen.

 

 

Pulmonary veins carry oxygen-rich blood to the left side of the heart.

 

 

The aorta, the main artery in the body, carries blood from the left side of the heart to the rest of the body through many branches of the arteries.

 

Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass into and out of tissue cells.

 

The veins then transport the blood back to the heart, and the process begins again.

 

vascular function

 

 

The function of blood vessels is to deliver blood to the organs and tissues in the body, and blood provides them with the oxygen and nutrients they need to function, and blood vessels also transport waste and carbon dioxide away from the organs and tissues of the body, and it is worth noting that each type of vessel The circulatory system performs a different function, and the following is an explanation of it:

 

 

Arteries: They are strong and muscular blood vessels, and they carry oxygen-rich blood from the heart to the body, and they deal with a large amount of force and pressure as a result of blood flow, but they do not carry a large amount of blood, as only about 10% to 15% of The body’s blood is in the arteries.

 

Capillaries: They are small blood vessels that have thin walls, and it is possible for oxygen and nutrients in the blood to move through the walls to reach the organs and tissues, and also works to get rid of waste in the tissues, and it is worth noting that the capillaries are the place where the exchange of Oxygen and nutrients to carbon dioxide and waste.

 

 

Veins: unlike arteries, veins do not have to carry high pressure blood, but they must carry large amounts of deoxygenated blood back to the heart. Thin, less flexible walls help to deal with large volumes and low pressure. Most veins include: Valves that open and close, which control the process of blood flow and maintain the flow in one direction, as approximately 75% of the blood is in the veins.
