Heyaa !!!

hers a happy ans to ur question :-)
what functions as a double from when you run for sometime or do any strenous physical activity your heart beats faster this is because at such times the body need more oxygen to release more energy through respiration to supply more oxygen the blood flows faster .
impure blood from the veins flows into the right Atrium of the heart from here the blood enters the right ventricle through an opening .
the impure blood is transported from the right ventricle to lungs by the pulmonary artery . gaseous exchange takes place in lungs the blood gives off carbon dioxide and take in oxygen . oxygen rich blood is carried to the left Atrium by pulmonary vein . from here the blood flows through and opening in to the left ventricle .
the left ventricle pumps oxygen rich blood to every part of the body through aorta . The aorta is the largest artery in the body the oxygen is then used by the cell . The cells produce carbon dioxide the blood takes in carbon dioxide and returns to the right ventricle of the heart the blood is now come back into the lungs .
