Structures of the Heart

• Chambers

  • Atria
  • Ventricles

• One way valves from atria to ventricle

  • What are the valves in the heart called ;; Atrioventricular valves, tricuspid and mitral

  • On side of ventricles we have papillary muscles that help the valves stay where they are.

• Semilunar valves are between the right ventricle and pulmonary arteries.

• Aortic semilunar valves seperates left ventricle from aorta, which will then send blood around the body.
