Final answer:
The term "pulmonary" is related to the lungs, as it refers to the pulmonary circulation system that carries blood between the heart and lungs for gas exchange.
Step-by-step explanation:
Saying something is "pulmonary" means that it is related to your lungs. The pulmonary circulation is a part of the cardiovascular system that carries blood between the heart and lungs. This process involves deoxygenated blood leaving the right ventricle through pulmonary arteries, which transport it to the lungs for gas exchange. In the lungs, the blood releases carbon dioxide and absorbs oxygen. The now oxygenated blood returns to the left atrium of the heart through pulmonary veins. Hence, the correct answer to your question is B. Lungs.
