Which brain region controls vital functions such as heartbeat and breathing?

• A. Brainstem
• B. Cerebral cortex
• C. Hypothalamus
• D. Cerebellum

Answer: (A)

Vital life-support functions are governed by the brainstem. The medulla oblongata within the brainstem houses the primary respiratory and cardiovascular centers that set the rate and depth of breathing and adjust heart rate in response to chemical signals. The pons helps shape the breathing pattern. Higher brain areas like the cerebral cortex manage conscious thought and voluntary actions; the hypothalamus modulates autonomic tone but does not directly drive the core rhythm of breathing and heartbeat; the cerebellum coordinates movement. So, the brainstem is the region that controls heartbeat and breathing.
