Arteries carry oxygen-rich blood away from the heart to all of the body's tissues.

Most of the time, arteries carry oxygen-rich blood within them.

The left ventricle pumps the oxygen-rich blood to the body.

The second pump delivers oxygen-rich blood to every part of your body.

Ischemia means that oxygen-rich blood is not getting where it needs to go, in this case to the heart.

They are red in color because the oxygen-rich blood shows through the non-pigmented skin.

These actions may help to increase the amount of oxygen-rich blood in your brain, heart, and muscles.

This results in oxygen-rich blood flowing back into the right side of the heart.

The oxygen-rich blood further enables energy delivery to their muscles.

This makes the heart work even harder to pump oxygen-rich blood throughout the body.
