Central chemoreceptors of the central nervous system are located on the ventrolateral medullary surface.
olfactory receptors
An example of direct chemoreceptors are the cells located on the tongue. When people taste food, it is because these cells respond to the chemicals in the food, sending a signal to thebrain to let the brain know about what's happening in the mouth. Specific regions of the mouth have areas which are targeted towards specific tastes, such as salty and sweet. This explains why foods can taste different as they are chewed and swallowed, and also why some foods have an aftertaste, as certain chemicals can take longer to stimulate the chemoreceptors.
pH. When CO2 (carbon dioxide) builds-up in the blood, in forms an acid compound with water called "carbonic acid." CO2 + H2O H2CO3
The baroreceptors, located in the carotid sinuses, respond to changes and absolute levels of blood pressure. These nerves go to centers in the brain stem and trigger changes in heart rate and venous tone.
chemoreceptors
Pressoreceptors are sensors located in blood vessels that detect changes in blood pressure. They send signals to the brain to help regulate and maintain blood pressure within a normal range. This feedback system is crucial for homeostasis and ensuring adequate blood flow to organs and tissues.
Central chemoreceptors of the central nervous system are located on the ventrolateral medullary surface.
The function of the chemoreceptors in regulating breathing is that they respond to low levels of oxyhemeglobin.

The receptors in the human nose are primarily chemoreceptors. These specialized cells detect chemical molecules in the air and help us perceive various smells.
Taste and smell receptors are classified as chemoreceptors because they both respond to chemical stimuli. These receptors detect specific molecules in the environment and send signals to the brain, which are then interpreted as taste or smell.
Chemoreceptors
Chemoreceptors bind to specific chemical substances, typically gases, ions, or molecules relevant to physiological processes. For example, in the respiratory system, chemoreceptors respond to changes in carbon dioxide, oxygen, and pH levels in the blood. In taste and smell, chemoreceptors interact with food molecules and odorants, respectively, to trigger sensory signals. This binding initiates a cascade of physiological responses that help maintain homeostasis and perception.
