Question

Quizplus · Accepted Answer

Chemoreceptors are specialized receptor cells that detect changes in the concentration of chemicals in body fluids. Examples include receptors that detect changes in pH, oxygen, and carbon dioxide levels. Photoreceptors respond to light, mechanoreceptors respond to mechanical stimuli such as pressure or stretch, thermoreceptors respond to changes in temperature, and proprioceptors respond to changes in body position and movement.
