List in order the types of blood vessels travels through as it goes from heart to body cells and back againWhat happens near cells?

Blood travels through the following types of blood vessels as it goes from the heart to body cells and back again:

1. Aorta: The aorta is the largest artery in the body and carries oxygenated blood away from the heart.

2. Arteries: Arteries are blood vessels that carry oxygenated blood away from the heart to various tissues and organs in the body.

3. Arterioles: Arterioles are small arteries that branch off from larger arteries and lead to capillaries.

4. Capillaries: Capillaries are the smallest blood vessels and allow for the exchange of oxygen and carbon dioxide between the blood and the surrounding tissues.

5. Venules: Venules are small veins that collect deoxygenated blood from capillaries and merge to form larger veins.

6. Veins: Veins are blood vessels that carry deoxygenated blood back to the heart.

7. Superior and inferior vena cava: The superior vena cava collects deoxygenated blood from the upper body, while the inferior vena cava collects deoxygenated blood from the lower body. Both vena cavae empty into the right atrium of the heart.

Near cells, capillaries allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. Oxygen and nutrients from the blood diffuse out of the capillaries into the interstitial fluid, which is the fluid that surrounds cells. At the same time, carbon dioxide and waste products diffuse from the interstitial fluid into the capillaries.
