The Heart
The heart is a large muscle that pumps
blood around the body using a double
circulatory system.
The blood enters the heart through the vena
cava from the body, it flows through the
right atrium and ventricle and out of the
heart through the pulmonary arteries to the
lungs. From the lungs the blood re-enters
the heart through the pulmonary veins, it
then flows through the left atrium and
ventricle and out of the heart through the
aorta and around the rest of the body.
The values in the heart prevent backflow
of blood




In the right atrium wall the sinatorial node
(pacemaker cells) produce an electrical signal,
the atria then contract. The atrioventricular
node delays the impulse by 0.15s as to allow
the ventricles to fill with blood.The ventricles
then contract.
