Partial Pressure

The pressure exerted by an individual gas in a mixture.

Dalton’s Law of Partial Pressure

In a mixture of gases, the total pressure of the mixture is the sum of the individual gases.

Fick’s Law of Diffusion

The rate of diffusion of a gas across a membrane depends on the difference in partial pressure and the surface area of the membrane.

Bohr Effect

The displacement of the oxygen-haemoglobin dissociation curve by a change in pH.

Utilization Coefficient

The fraction of the blood that gives up its oxygen as it passes through the capillary bed.

Haldane Effect

The phenomenon where the binding of oxygen with haemoglobin displaces carbon dioxide from the blood.

Oxyhaemoglobin

Haemoglobin that is bound to oxygen.

Deoxyhaemoglobin

Haemoglobin that is not bound to oxygen.

Carbonic Anhydrase

An enzyme that catalyzes the conversion of carbon dioxide and water into carbonic acid.

Chloride Shift

The exchange of bicarbonate ions (HCO3-) for chloride ions (Cl-) in red blood cells.
