the pressure exerted by one gas in a mixture

states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases

of the central nervous system, located on the ventrolateral medullary surface, are sensitive to the pH of their environment

so named because they are sensory extensions of the peripheral nervous system into blood vessels where they detect changes in chemical concentrations

named for Josef Breuer and Ewald Hering,[1][2][3] is a reflex triggered to prevent over-inflation of the lungs

(also known as respiratory depression) occurs when ventilation is inadequate (hypo meaning "below") to perform needed gas exchange. By definition it causes an increased concentration of carbon dioxide (hypercapnia) and respiratory acidosis

occurs when the rate and quantity of alveolar ventilation of carbon dioxide exceeds body's production of carbon dioxide.[1][2] Hyperventilation can be voluntary or involuntary.

A tiny, thin-walled, capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place.

openings in the interalveolar septa of the lung that permit air flow between adjacent alveoli

consists of alveolar squamous cell, the fused basement membrane and the capillary endothelial cell.

(or dust cell) is a type of macrophage found in the pulmonary alveolus, near the pneumocytes, but separated from the wall.

describe diffusion and can be used to solve for the diffusion coefficient, D. They were derived by Adolf Fick in 1855.
