The medulla oblongata plays a crucial role in assisting with respiration. This part of the central nervous system is located at the base of the brainstem and is responsible for autonomic functions, including the regulation of breathing. It contains vital centers that control the rhythm and depth of respiration. Specifically, the medulla responds to changes in carbon dioxide and oxygen levels in the blood, ensuring that proper gas exchange occurs and maintaining homeostasis.

The cerebrum primarily handles higher brain functions such as thought, perception, and voluntary movement, rather than automatic processes like breathing. The cerebellum is mainly involved in coordination and balance and does not directly control respiratory functions. The thalamus acts as a relay station for sensory and motor signals and is not responsible for the regulation of respiration. Thus, the medulla oblongata is the key area of the central nervous system that assists directly in the process of respiration.
