Chemoreceptors are located in the central part of the human respiratory system.

Take a second and breathe in.What do you like to smell?Do you ever wonder how you can smell your roommate's dirty socks?How do you like the taste of potato chips?

The short answer is that we have chemicals in our blood and in what we eat and smell.The chemoreceptors send messages to our brains to get a response.We may be told not to eat rotten food or to flee from the smell of smoke by these responses.Our heartbeat and respiration rates are controlled by chemoreceptors that detect carbon dioxide, oxygen, and pH levels in the blood.

The cells in our bodies are designed to be sensitive to light and sound.Even if you don't like a smell, the receptors act like little fingers that grab things around them and then tell your brain what they found.

The ligands are designed to detect.The key word here is'specific'.Thereceptor that's specifically designed to detect it will only convey messages about the ligand.This specificity is called a lock and key fit.

The sensation that you have starts with a cell in your body.Chemreceptors are located in the sensory organs of the body.

The taste buds on your tongue are designed to detect certain tastes, like sweet and salty.Each taste bud releases a different signal when activated by a specific chemical taste.

Your sense of smell comes from the olfactory bulb, an organ in your nose that has different parts that detect different types of odors.The scent of apple pie baking would be detected by a different area of the brain than the one that would detect your roommate's socks.The brain uses neurotransmitters, which are brain chemicals that transmit signals from one cell to another, to convey an odor.

Chemoreceptors can be found in our hearts and heads.If you've ever felt short of breath because of exercise or nervousness, the chemoreceptors in your body have detected that your oxygen and carbon dioxide levels are too low.

The central nervous system is aware of the levels of oxygen and carbon dioxide in the blood.The levels of carbon dioxide and oxygen are monitored by the central chemoreceptors, located in the respiratory center at the base of your brain.If your oxygen levels are too low, your central and peripheral chemoreceptors will send a message that will cause an increase in respiration.

Now that we know the function of chemoreceptors, let's look at how they communicate with the brain.Our cells communicate with each other through cell signaling.A signal is sent to the brain when enough ligands are bound.

Cell signaling is done by action potentials, which are short electrical impulses that occur when an electrical charge is released.An action potential will allow the cell to open if the threshold level is met.The neurotransmitters are sent to the central nervous system when calcium enters the cell.The appropriate sensation is detected by the organisms.After a short period of time, the cell closes and returns to its resting state.

All of the chemoreceptors send messages in this way.It doesn't take much effort to smell your roommate's feet, it happens almost instantly.Our senses give us information quickly so that we can respond.Most people don't like bitter flavors of poisons because they have a bitter taste.In the past, our ancestors learned that the tastes of salty and sweet were connected to what they needed to survive.

Chemoreceptors are found on sensory organs.They sit on the cell membranes.When enough ligands bind to a group of chemoreceptors, an action potential is released which causes the cell to open or depolarize.Calcium enters the cell, which causes neurotransmitters, brain chemicals that transmit signals to be released, and to send information to our brains about tastes, smells, or chemical levels in our blood so that our bodies can sense them.
