Respiratory system divisions?
Upper and lower tracts with specific roles.
Alveoli — function?
Gas exchange sites in lungs.
Gas exchange site?
Occurs mainly in alveoli via diffusion.
Gas exchange — process?
Oxygen in, carbon dioxide out.
NIV modes?
Includes CPAP and BiPAP for support.
Diffusion — role in gas exchange?
Passive movement of gases across membranes.
Partial pressure — significance?
Determines gas movement direction.
Hemoglobin — role?
Transports oxygen in blood.
Oxygen diffusion — occurs?
Across alveolar-capillary membrane.
Carbon dioxide — vehicle for elimination?
Diffuses from blood to alveoli.
