Why do we need arteries?

The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.

What happens when you hit an artery?

Hitting an artery can be painful and dangerous. Arterial blood travels away from the heart so whatever is injected goes straight to body limbs and extremities. Injection particles get stuck in blood capillaries and cut off circulation. This can result in a lack of blood flow, eventually causing the tissue to die.

Which leg has the main artery?
