B. Tricuspid and bicuspid valves open.
C. Action potential is conducted from SAN to AVN.
D. Blood from the pulmonary veins and vena cava flows into the left and right ventricles, respectively through the left and right atria.
E. The semilunar valves are closed.
Read the two statements provided and select the correct option:
I. Veins have valves which prevent the backflow of blood.
II. Flow of blood is not very fast in veins as there is low pressure.
When the blood is present in the blood vessel, its fluidity must be maintained. When the blood comes out of the body, it should get clotted. When these two conditions are not maintained many abnormalities would occur in our body. Explain those abnormalities.
