Pulmonary circulation transports oxygen-poor blood from the right ventricle to the ________, where blood picks up a new blood supply.
A. Heart
B. Lungs
C. Brain
D. Extremities
I said A but it was wrong. I want to say B
B is correct!
You're correct, the answer is B. Pulmonary circulation transports oxygen-poor blood from the right ventricle to the lungs, where blood picks up a new blood supply of oxygen.
To determine the correct answer, let's go through the explanation together.
Pulmonary circulation is responsible for the movement of blood between the heart and the lungs. It begins when the oxygen-poor blood is pumped out from the right ventricle of the heart. The main purpose of pulmonary circulation is to oxygenate the blood and remove carbon dioxide.
From the given options (A. Heart, B. Lungs, C. Brain, D. Extremities), it is clear that the correct answer is B. Lungs. In the lungs, blood exchanges carbon dioxide for oxygen through the process of respiration. This oxygen-rich blood then returns to the heart through the pulmonary veins, where it enters the systemic circulation to supply oxygen to the body's tissues, including the brain (option C) and the extremities (option D).
Therefore, the correct answer is B. Lungs.
