active transport
The left ventricle of the heart pumps blood into the aorta. From there, it travels to all body tissues.

Systemic circulation
Veins carry blood from the tissues to the heart.
Veins are the type of blood vessel that drains blood from tissues and returns it to the heart.
The Aorta is the main artery coming out of the heart's left ventricle and allows blood to travel to all the body tissues except the lungs.
The right side of the heart (right atrium and right ventricle) receives blood low on O2.
The blood returns to the heart through veins.
Veins and arteries distribute blood throughout the body. The blood circulates through the heart and back to the body continuously.

I travels as it does with any human, except as he's an athlete he has a larger, more muscular heart. This gives him better blood circulation.
