THE HEART
The Cardiovascular system, composed of the heart and blood vessels, is responsible for circulating blood throughout your body to supply the tissues of the body with oxygen and nutrients.
The heart is the hardest working muscle in the human body and is about the size of an adult’s fist. It is made
up of four chambers (two atria and two ventricles)
They receive blood from the body and pump blood out.
Blood vessels compose a network of arteries and veins that carry blood throughout the body:
Arteries transport blood from the heart to the body tissues.
Veins carry blood back to the heart.
There are four valves to prevent backward flow of blood: Each valve is designed to allow the forward flow of blood and prevent backward flow.
Tricuspid Valve:
This valve separates the right atrium from the right ventricle, and
regulates the blood flow between them. Tricuspid valves allow blood
to flow from the right atrium into the right ventricle, and prevent back
flow of the same.
Pulmonary Valve:
This valve separates the right ventricle from the left pulmonary artery.
These valves prevent and control the flow of blood from the right
ventricle into the left pulmonary artery.
Mitral Valve:
Tricuspid valve or Mitral valve separates the left ventricle from the left atrium.
Aortic Valve:
This valve separates the left ventricle from the aorta, and controls the blood flow from the ventricle into the rest of the body.
