What is the function of the hindbrain in the human body?

The function of the hindbrain in the human body is to control vital, automatic, and involuntary functions such as heart rate, breathing, and blood pressure. It is responsible for regulating basic life-sustaining processes, such as digestion, circulation, and respiration.

The hindbrain also plays a significant role in coordinating movement and balance, as it contains the cerebellum, which is responsible for fine-tuning muscle movements and maintaining balance and posture.

Therefore, the correct answer is "Controls heart rate, breathing."
