Chemoreceptor
The name of the type of receptor that responds to changes in the concentration of chemicals is a chemoreceptor. These receptors are found in various parts of the body, such as the nose and taste buds, and they help detect and transmit signals related to smell and taste.
Respiration responds to smaller changes in the concentration of oxygen than carbon dioxide
Senses changes both in and outside the body (the sensoryfunction).Interprets and explains the changes (the integrativefunction).Responds to the interpretation by making muscles interact and glands secrete hormones or other chemicals into the bloodstream (the motor function).
Receptor
Evolution/adaptation.
First of all, the change in internal conditions is registered by a chemo-receptor, like in the case of excess salt. This receptor in turn releases kinases, which signal the cell to produce a signalling molecule that will affect another cell's receptor or it's own receptor, depending on the circumstances. This chain reaction continues until it reaches a final effector cell which tackles the problem of higher salt concentration, like in this case, vasopressin would be released to dilate the blood vessels so that larger volume of water would flow. This volume is retained by the nephrons in kidney by reabsobing water from the urine formation process. The higher volume of water will dilute the excess salt and homeostasis would be maintained.
The Receptor senses changes in the environment and responds by sending information to the Control Center along the Afferent.

The receptors that are likely to detect changes in carbon dioxide and oxygen concentration in the blood are chemoreceptors located in the aorta and carotid arteries. These chemoreceptors detect changes in the pH of the blood and send signals to the brain to regulate breathing heart rate and other bodily functions. The receptors are sensitive to the following: Carbon dioxide concentration Oxygen concentration pH of the bloodThe chemoreceptors are located in the walls of the aorta and carotid arteries and are sensitive to the changes in carbon dioxide and oxygen concentrations. When the concentrations of these two gases change the chemoreceptors send signals to the brain which then responds with appropriate adjustments in breathing rate and heart rate.
Sensory receptors that are sensitive to chemicals are found in the nose and mouth. While chemicals can have a reaction on other parts of the body, the receptors located in the nose and mouth are capable of recognizing these sensations the most.

Muscle spindle receptors which are located in the belly's of muscles measure length of stretch and speed of change. They send this afferent neural information to the posterior horn of the spinal cord where and interneuron interprets the information and if the stretch is ballistic (if it changes length too rapidly) it will trigger an efferent motor unit, or many motor units, through the anterior horn of the spinal cord to contract the muscle.
