After a baby takes its first breath, which of the following organs is/are then immediately operative?

A. Brain
B. Heart
C. Lungs
D. Stomach

my answer is c.

That's not the only answer. What else does every living being need?

My option is one answer from four. And my answer was c. I understand that b. could be the answer.

Then yes, C is the answer.

Thanks Ms.Sue

You're welcome, Diana.

Your answer is correct! After a baby takes its first breath, the organ that immediately becomes operative is the lungs (Option C). When a baby is inside the mother's womb, it receives oxygen from the mother through the umbilical cord. However, once the baby is born, the umbilical cord is cut, and it needs to start breathing on its own. The first breath causes air to enter the baby's lungs, and this triggers various physiological changes in the body, such as the expansion of the lungs and the initiation of oxygen exchange with the bloodstream.
