Q

Artery, veins & Capillaries

A

Artery carry O blood away from heart, branch into smaller vessels ‘arterioles’ deliver to capillaries

Capillaries are tiny vessels connecting arteries and veins, one cell thick allows water, O, CO2 and other nutrients to move between blood and surrounding tissue

Veins carry deoxygenated blood to heart
