The Medulla Oblongata, AKA the Brain Stem, is responsible for all involuntary actions, including heart rate.

The adrenal medulla is the part of the brain responsible for the release of adrenaline, when the adrenaline is released into the blood, the SAN is stimulated to work faster and increase your heart rate, this happens when playing sport or during your fight or flight response. However, the heart is not controlled by your brain as it is a myogenic muscle (self-exciting) this means that if you were to remove the heart from a body it would continue to beat. The sino-atrial node is responsible for the excitation of the heart. :) Hope this helps. Steph :)

The hypothalamus is the part of the brain responsible for regulating blood pressure, heart rate, body temperature, hunger, and thirst. Additionally, the hypothalamus plays a role in regulating emotions and behaviors related to trust.
The smallest part of the brain is the brainstem, located at the base of the brain. It connects the brain to the spinal cord and is responsible for basic life functions like breathing, heart rate, and digestion.

The lowest part of the human brain is the medulla oblongata, which is located at the top of the spinal cord. It is responsible for controlling basic life functions such as breathing, heart rate, and blood pressure.
