a Regulates blood pressure b Filters blood c Acts as the heart's natural pacemaker d Pumps blood 22 What happens to the pressure in the ventricles during systole? a It decreases b It remains constant c It increases significantly d It fluctuates mildly 23 What is the term for the electrical impulse that initiates the cardiac cycle? a Action potential b Resting potential c Repolarization d Hyperpolarization 24 What is venous return? a The exchange of gases in the lungs. b The flow of blood back to the heart from the body. c The process of blood clotting. d The flow of blood from the heart to the body. 25 Which vessel is primarily responsible for venous return?

a It regulates heart rhythm. b It aids in drawing blood back to the heart during inhalation. c It filters blood. d It increases blood pressure. 33 What is the effect of dehydration on venous return? a It has no effect. b It can decrease venous return due to lower blood volume. c It only affects arterial flow. d It increases venous return. 34 What is the primary function of the ductus arteriosus in fetal circulation? a To supply oxygen to the fetus. b To connect the umbilical cord to the heart. c To connect the pulmonary artery to the aorta. d To filter waste from the blood. 35 What structure allows blood to bypass the lungs in fetal circulation? a Umbilical vein. b Ductus venosus. c Pulmonary artery. d Foramen ovale. 36 Which vessel carries oxygenated blood from the placenta to the fetus? a Umbilical vein. b Ductus arteriosus. c Aorta. d Umbilical artery. 37 What happens to the ductus arteriosus after birth? a It becomes the pulmonary artery. b It closes and becomes the ligamentum arteriosum. c It turns into the aorta. d It remains open for life. 38 What is the role of the placenta in fetal circulation? a To exchange nutrients and waste between mother and fetus. b To filter blood from the fetus. c To produce hormones only. d To supply oxygen directly. 39 Which structure is responsible for carrying deoxygenated blood from the fetus to the placenta? a Umbilical vein. b Ductus venosus. c Aorta. d Umbilical arteries. 40 What is the purpose of the foramen ovale? a To connect the aorta to the pulmonary artery. b To allow blood to flow from the right to the left atrium. c To carry oxygenated blood. d To filter waste from the blood. 41 What is the ductus venosus? a A structure that filters waste. b A vessel that carries oxygenated blood. c A connection between the heart and lungs. d A vessel that allows blood to bypass the liver. 42 How does fetal circulation differ from adult circulation?
