The ________ circulation picks up oxygen for cellular use and drops off carbon dioxide for removal from the body.

A. pulmonary

B. interlobular

C. respiratory

D. bronchial

Answer Explanation:

Our blood flow is separated into two major pathways, listed below:

Systemic circulation - this comes from the left side of the heart and pumps blood to all working tissues, including the brain, muscle, heart, and other organs, and then into the right side of the heart.
Pulmonary system - this comes from the right side of the heart, and pumps blood to the alveolar sacs within the lungs, and then into the left side of the heart

In pulmonary circulation: The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide.

Therefore, the Correct Answer is A.
