Answer:
a) Aorta
b) Right ventricle
Step-by-step explanation:
a) The blood comes in through Vena Cava, into the right Atrium and to right ventricle. Right ventricle pumps it into lungs through Pulmonary artery.
So Aorta is not related to all this phenomenon of right chambers of Heart.
b) In the left side of the heart, the blood comes from lungs through Pulmonary Veins into the Left Atrium then to Left Ventricle. Left ventricle pumps it into the body through Aorta. Coronary arteries are present both sides of the heart.
So Right ventricle is relatively unrelated to all these structures.
