Question

Are arteries thick or thin?

Answer 1

Arteries:

1. Arteries are blood vessels that carry oxygenated blood away from the heart to various parts of the body.
2. An exception is the pulmonary artery which carries deoxygenated blood from the heart to the lungs for oxygenation.
3. Blood flows through arteries under high pressure due to the pumping pressure of the heart.
4. The diameter of the artery is adjusted based on the blood pressure and blood flow.
5. Arteries have thick muscular walls to withstand high blood pressure.
