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
diaphragm
major muscle of inspiration, separates thoracic and abdominal cavity
external intercostals
muscle of inspiration, raises ribs and enlarges rib cage
external obliques
expiration, compress abdomen
internal intercostals
expiration, depress rib cage
internal obliques
expiration, compress abdomen
rectus abdominis

transversus abdominis
com press abdomen
