Central chemoreceptors of the central nervous system are located on the ventrolateral medullary surface.
in the brain
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.

olfactory receptors
There is a desert biome in central Australia.
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.

The two groups of chemoreceptors are the following:1- Central Chemorecepto- In the medulla oblongata, which measures PO2, PCO2 and the pH of CSF. (Cerebral spinal fluid)2- Peripheral Chemoreceptor - Contained in small nodules within the aorta and carotid bodies.
