Exercise 10

List and identify the functions of the chemoreceptors that contribute to the control of breathing.

Step 1 of 2

The neurons present in the respiratory control center are influenced by several types of receptors. These receptors are classified into neural and humoral. While neural inputs are from the afferent and efferent inputs to the respiratory control center, humoral input is influenced by blood borne stimuli that reach a specialized chemoreceptor.

The chemoreceptor is a molecule which when binds to its ligand (the ligand is usually the stimulus), reacts to it depending on the strength of the stimulus and reacts appropriately.
