respiration

respiration

gas exchange (O2 from atmosphere to blood, CO2 from blood to atmosphere)

internal respiration

occurs in metabolizing tissue, O2 out of blood, CO2 out of cells

external respiration

occurs in lungs, O2 into blood and CO2 into alveolar air

inhalation (inspiration)

taking air into lungs, active phase of ventilation, result of muscle contraction

exhalation (expiration)

letting air out of lungs, result of relaxation of diaphragm and elastic recoil of tissue (decrease in thoracic volume and increase in intraavleolar pressure
