The pons, a structure in the brainstem, works with the medulla oblongata to regulate breathing. The pons helps coordinate the rhythm and depth of breathing by sending signals to the respiratory muscles.
The medulla oblongata, located in the brainstem, sets the basic rhythm of breathing. It contains the respiratory center that controls the rate and depth of breathing through signals sent to the diaphragm and intercostal muscles.
Breathing is controlled mainly by the inspiratory and expiratory centres in the medulla oblongata of the brain.Pons varolli also helps in regulation of the actions of medulla oblongata.
The windpipe is also known as the trachea. It is a tube-like structure that carries air to and from the lungs during breathing.
The brain and the lungs aid the breathing of humans. The brain tells the body when to inhale and when to exhale. The lungs take in the air and disburse the oxygen throughout the body through the blood, starting in the heart.
