1.	What happens when the ventricular pressure decreases?(a) Blood from pulmonary artery flows into ventricle(b) The semilunar valves remain open(c) The tricuspid and bicuspid valves open(d) Atrial pressure decreasesI got this question in exam.My question is taken from Human Circulatory System topic in division Body Fluids and Circulation of Biology – Class 11
Answer» The correct answer is (c) The tricuspid and BICUSPID valves open To explain I would say: The ventricular pressure decreases during the ventricular diastole or when the ventricles RELAX. The tricuspid and bicuspid valves open to ALLOW blood to flow from the ATRIA to the ventricles.
