The heart chamber has to generate enough pressure to push the blood to all the parts of the body.
Arteries are blood vessels, the network of pathways through which the oxygenated blood travels away from the heart to various cells, tissues and organs of the human body.
- If arteries have thin walls they would burst because of high blood pressure.
- That is why arteries have thick walls. Because the heart pumps blood at high pressure.
- They must be able to withstand the tremendous pressure from a beating heart.
- Veins have thinner walls because they need more room to hold blood.
