Respiratory physiology

Respiratory physiology

Respiratory physiology is the branch of human physiology focusing upon respiration.

Topics include:

Volumes

Mechanics

Breathing in, or inhaling, is usually an active movement. The contraction of the diaphragm muscles cause a pressure variation, which is equal to the pressures caused by elastic, resistive and inertial components of the respiratory system.

begin{align} P &= P_{el} + P_{re} + P_{in} P &= EV + Rdot{V} + Iddot{V} end{align}

Where Pel equals the product of elastance E (inverse of compliance) and volume of the system V, Pre equals the product of flow resistance R and time derivate of volume V (which is equivalent to the flow), Pin equals the product of inertance I and second time derivate of V. R and I are sometimes referred to as Rohrer's constants.

Circulation, ventilation, and perfusion

Gas exchange/transport (primarily oxygen and carbon dioxide)

Control and response
