Answer 1

Hello!! Your answer would be C - Medulla oblongata. The medullary respiratory center includes two groups of neurons that extend throughout the length of the medulla oblongata. They are called the ventral respiratory group and the dorsal respiratory group. The ventral respiratory group is responsible for regulating inspiration and expiration. The dorsal respiratory group stimulates the inspiratory muscles, like the diaphragm (near bottom of ribs). It also helps process sensory information related to the respiratory system. Neurons in the brainstem are a part of the pontine respiratory group which limits inspiration and help the rhythm of breathing. I hope I helped give you a better understanding. Have a great evening!!

Answer 2

The answer is:

C - Medulla oblongata.

The medulla oblongata transmits signals between the brain and the spinal cord. It’s responsible for controlling involuntary actions such as breathing, blood pressure, and heart rate.
