Four MAIN Valves In The Heart

Four Main Valves In The Heart

Latidos

TRICUSPID VALVE

  • Closes off the upper right chamber (or atrium) that holds blood coming in from the body.
  • Opens to allow blood to flow from the top right chamber to the lower right chamber (or from right atrium to right ventricle).
  • Prevents the back flow of blood from the ventricle to the atrium when blood is pumped out of the ventricle.

PULMONARY VALVE

  • Closes off the lower right chamber (or right ventricle).
  • Opens to allow blood to be pumped from the heart to the lungs (through the pulmonary artery) where it will receive oxygen.

MITRAL VALVE

  • Closes off the upper left chamber (or left atrium) collecting the oxygen-rich blood coming in from the lungs.
  • Opens to allow blood to pass from the upper left side to the lower left side (or from the left atrium to the left ventricle).

AORTIC VALVE

  • Closes off the lower left chamber that holds the oxygen-rich blood before it is pumped out to the body.
  • Opens to allow blood to leave the heart (from the left ventricle to the aorta and on to the body).

Essentials for properly working valves

  • The valve is properly formed and flexible.
  • The valve should open all the way so that the right amount of blood can pass through
  • The valve closes tightly so that no blood leaks back into the chamber.
