Answer 1

                                              HEART ATTACK 
              
                 Heart is the most essential part of our body.It pumps the blood to all the parts of our body.Heart has 4 lobes.upper ones(two) can be stated as artery and the lower ones(two) can be stated as ventricles.left part of our heart contains de-oxygenated blood where as right part of our heart contains oxygenated blood.
       There are many types of heart diseases.every part in our body requires some energy to work efficiently.Similarly heart has muscles to pump.this muscles need energy...So this muscles also need energy.The energy is transported to the muscles(heart) through coronary arteris.If there is a blockage in this coronary arteries or veins then the blood can't reach to the muscles of heart.This waythe muscles of heart stop working,thus causing heart attack!!!
