Answer:
Working of Human Heart :
→ First of all, all the deoxygenated blood from the body with the help of superior and inferior vena cava came in heart.
→ After it, it came in Right atrium and then Right ventricle.
→ Contraction of auricles derives most of the blood in into the ventricle. At the end of the auricular systole, auricles start relaxing and the contraction of the ventricles simultaneously.
→ As the contraction of the ventricles begins, the pressure of the blood in the auricles rises. With this pressure, the flaps of the auricular ventricular (A-V) valves are pushes up and meet to close the A-V apertures. This tight closure of the A-V valves at the start of the ventricular contraction produces the first heart beat, which is "Lub".
→ Now the ventricles start relaxing. The semilunar valve close as they get filled the blood trying to return and meet together, closing the outlets of the great arteries.
→ The closing of the semilunar valves at the start of diastole produces the second heart sound "Dup".
