ANATOMY AND PHYSIOLOGY :HEART
1.The heart is situated in the :
 Thoracic cavity.
2.The function of coronary artery is to :
  Supply Oxygen and nutrients to cardiac muscles.
3 Time to complete a cardiac cycle is :
  0.8 seconds
4. The cardiac output termed as ;
    the total volume of blood ejected in one minute.
5. Stroke volume is termed as :
   The total volume of blood ejected with each heart beat.
6. Normal pacemaker of heart is :
    S.A node.
7. S.A node sends impulses at a rate of :
  60 to 100 times per minute.
8. The inner most layer of heart is known as:
    Endo cardium.
9. he outer layer of heart is known as :
  Pericardium.
10. The heart gets its nourishment through :
   Coronary Arteries.
11. Left coronary artery supplies blood to :
    All chambers of heart except right atrium.
12. The arteries which encircles the heart is :
    Coronary Artery
13. The artery arising from left ventricle :
    Aorta.
14. Muscular layer of Heart :
     Mayocardium.
15. The total volume of blood ejected out in one minute :
      Cardiac Output.
16. The middle muscular layer of heart :
       Mayocarium.
17. The semilunar valve at the exit of the right ventricle :
     Pulmonary Valve.
18. Mitral Valve also known as :
     Bicuspid Valve.
19.The cardiac functions are regulated by :
   Autonomic nervous system.
20. The heart chambers relax and fill with blood :
    Diastole.
