chemoreceptor

Chemoreceptors are specialized sensory cells that detect chemical changes in the environment or within the body. They play a key role in monitoring substances like oxygen, carbon dioxide, and other chemicals. In the body, chemoreceptors help regulate vital functions such as breathing by sensing carbon dioxide levels in the blood or oxygen levels in the lungs and sending signals to the brain to adjust breathing rate accordingly. They are essential for maintaining the body's chemical balance and ensuring proper respiratory and cardiovascular function.
