The path of blood through the heart begins with the right atrium receiving blood, which has circulated through most of the body. This blood is relatively low in oxygen because most of it has already been delivered to different organs and tissues.
After leaving the LV, blood now rushes through the aorta (pronounced a-OR-tah). The aorta is the main highway blood vessel that supplies blood to the head, neck, arms, legs, kidneys, etc. Blood is brought to these organs and limbs via branches that originate from the aorta. The cells within each part of the body pick up oxygen and nutrients from the blood.
