Blood travels through the heart twice before returning to the body
Blood travels through the heart twice before returning to the body

The double circulatory system


External view of the heart
External view of the heart the body

superior

vena cava

pulmonary

artery

aorta

pulmonary

vein

pulmonary

vein

coronary

artery

right atrium

left

ventricle

inferior

vena cava

right ventricle


The vena cava carries deoxygenated blood from the body to the right atrium
The vena cava carries deoxygenated blood from the body to the right atrium

superior

vena cava

(transports blood

from the head)

inferior

vena cava

(transports blood

from rest of body)




The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs

Pulmonary

Artery






The aorta carries the oxygenated from the left ventricle to the rest of the body
The aorta carries the oxygenated from the left ventricle to the rest of the body

Aortic arch

Aorta


Atrio ventricular valves prevent backflow of blood into the atria when ventricles contract
Atrio the rest of the body-ventricular valves prevent backflow of blood into the atria when ventricles contract

Tricuspid valves

Bicuspid valve

(mitral valve)

Tendon


The semi lunar valves prevent backflow of blood from the arteries into the ventricles
The semi-lunar valves prevent backflow of blood from the arteries into the ventricles

Aortic semi-lunar

valve

Pulmonary

semi-lunar

valve
