answer   =

  • cardiac cycle means time taken by heart to ending of one heart beat to starting of next  heartbeat
  • as we know heart is myogenic in nature and it works continously throw out the life heart get relax  simultaniously for  fraction of seconds
  • our heart beats 72  to 75 /min times
  • in our heart their are several valves which are play very important role in cardiac cycle . Genarally valve performs the function of preventing back flow of blood
  • their are important 4 events in cardiac cycle that are  
  • atrial systole
  • atrial diastole
  • ventricular systole
  • ventricular diastole

  • Our heart has 4 chamber the right ventricle pump deoxygenated blood while left ventricle carry oxygenated blood
  • The cardiac cycle initate during atrial systole becoz  SA node is there which start the cardiac events
  • atrial systole is for 0.1 sec in which tricuspid and bicuspid valves are open
  • here are timings takes for  complete the events
  • atrial systole =0.1
  • atrial diastole =0.7
  • ventricular systole = 0.5
  • ventricular diastole =0.3

Cardiac Cycle is the cyclic event that occurs in the heart contraction and relaxation.

Explanation:

  • Heart is the blood pumping organ of our body.
  • It pumps blood all over the body by its strong muscles.
  • The heart muscles are contracting and relaxing at regular intervals of time which leads to a rhythm of blood pushing through heart.
  • The events of heart contraction includes
  • A. Arterial systole,
  • B. Ventricular diastole,
  • C. Ventricular Systole and
  • D. Arterial diastole.
  • The arterial systole leads to pushing of blood to ventricle through auriculoventricular valves.
  • The Ventricular systole leads to the pushing of blood from ventricles into aorta and pulmonary artery.
