    no i think that in q.8 its asked for the flow of ventricles and arteries becoz when blood enters the ventricles there is the movement of the blood frm auricles to ventricles is anterioventricular valves and from ventricles to arteries it is the semilunar valves.. so the answer is correct as per my view

      According to question….all options are wrong..as AV valves prevents backflow of blood from ventricle to the auricle…therefore answer should be only semi lunar valve..

      Question 8 all options are wrong . The valves which allow the flow of blood from ventricles to arteries are the pulmonary and the aortic semilunar valves

      I think q15 answer should be (b)
