Chemoreceptors are sensory receptors that can detect changes in hydrogen ion concentrations. These receptors are particularly sensitive to changes in pH levels in the body, helping to regulate processes such as breathing and maintaining blood pH balance.
Chemoreceptors, specifically peripheral chemoreceptors in the carotid bodies and aortic bodies, detect changes in blood gas concentrations. These receptors are sensitive to levels of oxygen, carbon dioxide, and pH in the blood and play a key role in regulating respiration to maintain homeostasis.
Air breathers are more sensitive to changes in carbon dioxide concentration than to changes in oxygen. Regulation of ventilation is normally driven by receptors that are sensitive to dissolved carbon dioxide levels and the acidity (pH) of the blood.

Thermoregulation receptors are sensory receptors in the skin and deep tissues that detect changes in body temperature. They send signals to the brain to help regulate the body's temperature by adjusting factors such as blood flow, sweating, and shivering to maintain homeostasis. Temperature receptors can be sensitive to both cold and warm stimuli.

Baroreceptors
Mechanoreceptors are sensory receptors that respond to mechanical forces such as pressure. Specialized types of mechanoreceptors include baroreceptors that detect changes in blood pressure and tactile receptors in the skin that respond to touch and pressure. These receptors help the body in detecting and responding to changes in pressure.
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.
The mechanoreceptor is the receptor sensitive to changes in pressure. It is responsible for detecting mechanical stimuli such as touch, pressure, and vibration and relaying this information to the brain.
Chemoreceptors sensitive to blood carbon dioxide levels are primarily located in the carotid bodies and aortic bodies. These receptors are responsible for detecting changes in blood pH and carbon dioxide levels, helping to regulate breathing rate to maintain proper gas exchange in the body.
Blood pressure receptors are found in the aorta (aortic baroreceptors) and carotid arteries (carotid sinus baroreceptors). These receptors detect changes in blood pressure and send signals to the brain to help regulate blood pressure.
Baroreceptors are sensitive to changes in pressure, such as those in blood vessels that help regulate blood pressure. Similarly, hair cells in the inner ear are sensitive to movement of fluid, allowing us to maintain balance and perceive sound.
