Arteries...
carry oxygen-rich blood away from the heart.
carry deoxygenated blood back to the heart.
carry deoxygenated blood away from the heart.
carry oxygen-rich blood back to the heart.
Veins...
carry oxygen-rich blood away from the heart.
carry deoxygenated blood back to the heart.
carry deoxygenated blood away from the heart.

What does the septum do?
Separate the left and right chambers.
Prevents mixing of blood.

The role of atrioventricular valves is to...
be a passage way/valve for blood to pass through to go around the heart.
connect all the four chambers.
guide the blood in the heart.
prevent back flow of blood between the atrium and ventricle.
The flow of blood in the heart is...
