Answer Details
The part of the brain that controls heart beat and breathing is the medulla oblongata. The medulla oblongata is located in the brainstem, which connects the brain to the spinal cord. It is responsible for controlling several involuntary functions, including heart rate, breathing rate, and blood pressure.
The medulla oblongata contains specialized neurons that form the respiratory and cardiovascular centers. These centers respond to changes in carbon dioxide, oxygen, and pH levels in the blood, as well as to signals from other parts of the body. For example, if carbon dioxide levels in the blood rise, the respiratory center in the medulla oblongata will increase breathing rate to remove excess carbon dioxide. Similarly, if blood pressure drops, the cardiovascular center will increase heart rate to maintain blood flow to the body.
Overall, the medulla oblongata plays a critical role in maintaining homeostasis and ensuring that the body's essential functions, such as breathing and heart rate, are properly regulated.
