Valves Backflow Blood Chordae Tendinae Prevents Ventricle Atrium

The tricuspid valve prevents backflow from the right ventricle to the right atrium, the bicuspid valve prevents backflow from the left ventricle to the left atrium, and semilunar valves prevent backflow into the heart from the aorta and pulmonary artery. Chordae tendinae ensure these valves do not invert under pressure.

The tricuspid valve prevents backflow from the right ventricle to the right atrium, the bicuspid valve prevents backflow from the left ventricle to the left atrium, and semilunar valves prevent backflow into the heart from the aorta and pulmonary artery. Chordae tendinae ensure these valves do not invert under pressure.

Front Describe the function of each of the valves and chordae tendinae
Back Valves and chorade tendinae:
  • Tricuspid valve prevents backflow of blood from right ventricle to right atrium
  • Bicuspid valve prevents backflow of blood from left ventricle to left atrium
  • Semilunar valves prevent backflow of blood into the heart from pulmonary artery and aorta
  • Chordae tendinae - make sure valves are not turned inside out by pressures exerted

(aortic and pulmonary valves are semilunar)
