Blood plasma
Blood plasma is a yellowish coloured liquid component of blood that normally holds the blood cells in whole blood in suspension; this makes plasma the extracellular matrix of blood cells.

Blood–brain barrier
The blood–brain barrier (BBB) is a highly selective semipermeable membrane barrier that separates the circulating blood from the brain and extracellular fluid in the central nervous system (CNS).

Carbon dioxide
Carbon dioxide (chemical formula) is a colorless gas with a density about 60% higher than that of dry air.

Carbonic acid
Carbonic acid is a chemical compound with the chemical formula H2CO3 (equivalently OC(OH)2).

Cerebrospinal fluid
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spinal cord.

Chemoreceptor
A chemoreceptor, also known as chemosensor, is a specialized sensory receptor cell which transduces (responds to) a chemical substance (endogenous or induced) and generates a biological signal.

Hypercapnia
Hypercapnia, also known as hypercarbia and CO2 retention, is a condition of abnormally elevated carbon dioxide (CO2) levels in the blood.

Medulla oblongata
The medulla oblongata (or medulla) is located in the brainstem, anterior and partially inferior to the cerebellum.
New!!: Central chemoreceptors and Medulla oblongata · See more »
PCO2
The pCO2, PCO2, p_\ceor P_\ce is the partial pressure of carbon dioxide (CO2), often used in reference to blood, but also used in oceanography to describe the partial pressure of CO2 in the Ocean, and in life support systems engineering and underwater diving to describe the partial pressure in a breathing gas.

Peripheral chemoreceptors
Peripheral chemoreceptors (of the carotid and aortic bodies) are so named because they are sensory extensions of the peripheral nervous system into blood vessels where they detect changes in chemical concentrations.

PH
In chemistry, pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution.

Pulmonary stretch receptors
Pulmonary stretch receptors are mechanoreceptors found in the lungs.
New!!: Central chemoreceptors and Pulmonary stretch receptors · See more »
Respiratory arrest
Respiratory arrest is caused by apnea (cessation of breathing) due to failure of the lungs to function effectively.
New!!: Central chemoreceptors and Respiratory arrest · See more »
Shock (circulatory)
Shock is the state of low blood perfusion to tissues resulting in cellular injury and inadequate tissue function.
New!!: Central chemoreceptors and Shock (circulatory) · See more »
Vasomotor center
The vasomotor center (VMC) is a portion of the medulla oblongata that, together with the cardiovascular center and respiratory center, regulates blood pressure and other homeostatic processes.
