Medulla
The part of the brain responsible for regulating sleep is the hypothalamus.
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.
Brain Stem
The Medulla Oblongata, AKA the Brain Stem, is responsible for all involuntary actions, including heart rate.
The hypothalamus, a region in the brain, plays a key role in regulating the sex drive.
The brainstem, specifically the medulla oblongata, is responsible for regulating automatic bodily functions such as breathing, heart rate, and blood pressure. This area of the brain controls essential functions to maintain life without conscious effort.
The brain hemisphere is located on the left side of the corpus collasum. This is responsible for regulating the activities on the right part of the body. Brain hemisphere is also responsible for speech and language functions.
The adrenal medulla is the part of the brain that keeps the heart beating
The brainstem, specifically the medulla oblongata, controls involuntary responses such as breathing, heart rate, and blood pressure. This region is responsible for regulating essential bodily functions to maintain homeostasis.
There is a part of the brain called the Medulla Oblongata which is responsible for breathing and vision. This is also known as the little brain. It is located at the very very back. It is a ver small part of the brain.
The medulla oblongata, located in the brainstem, is responsible for regulating heart rate and blood pressure during exercise. It sends signals through the autonomic nervous system to increase heart rate and dilate blood vessels in response to physical activity.
The heart has its own "nervous system" called "purkinje fibers", and so doesn't need the brain to beat ... but the thalamus [oldest part of the brain] does have "override" control via the autonomic nervous system (sympathetic by way of several unnamed nerves and parasympathetic by way of the Vagus nerve.
