The largest artery is aorta, the main high-pressure line connecting the left ventricle of the heart. The aorta branches into a network of smaller arteries throughout the body. The smaller branches of arteries are called arterioles and capillaries.

Which is bigger, artery or vein?

Arteries carry blood away from the heart and veins return blood to the heart. Veins are usually larger in diameter, carry more blood and have thinner walls in proportion to their lumen. Arteries are smaller, have a wall thickness proportional to their lumen, and carry blood at higher pressures than veins.

What is the thinnest artery called?

arterioles are the thinner arteries that branch from the ends of the arteries and carry blood to the capillaries. They face much lower blood pressure. Arterioles have much thinner walls than arteries, and they also use smooth muscle to control blood flow and pressure.

What is the most important artery in your body?

Do veins carry oxygen-rich blood?

Arteries (red) carry oxygen and nutrients from the heart to body tissues. veins (blue) Bring oxygen-poor blood back to the heart. Arteries start in the aorta, the large arteries leave the heart. They carry oxygen-rich blood from the heart to all tissues in the body.

Do arteries carry more blood than veins?

This makes the walls of the veins thinner than the walls of the arteries, which is related to less pressure in the blood in the veins than in the arteries. Because the walls of veins are thinner and less rigid than arteries, Veins can hold more blood.
