The medulla oblongata is part of the brain stem. It regulates functions such as heart rate, respiratory rate, and blood pressure.

That is correct! The medulla oblongata is located at the base of the brain, at the junction of the spinal cord. It plays a vital role in controlling various involuntary functions of the body, including heart rate, respiratory rate, blood pressure, and reflexes such as swallowing, vomiting, coughing, and sneezing. It also acts as a bridge connecting the brain to the spinal cord, allowing for communication between the two.
