Trace the pathway of blood through the pulmonary circuit, and state the importance of this special circulation.
a) Right atrium -> Right ventricle -> Lungs -> Left atrium -> Left ventricle; This circulation oxygenates the blood and removes carbon dioxide
b) Left atrium -> Left ventricle -> Body tissues -> Right atrium -> Right ventricle; This circulation deoxygenates the blood and removes waste products
c) Right atrium -> Right ventricle -> Body tissues -> Left atrium -> Left ventricle; This circulation oxygenates the blood and removes waste products
d) Left atrium -> Left ventricle -> Lungs -> Right atrium -> Right ventricle; This circulation deoxygenates the blood and removes carbon dioxide
