breathing
external respiration
internal respiration
cellular respiration
bulk flow of air to alveoli; filter air; moisten air; warm air
pharynx
epiglottis
hair, mucus, blood capillaries
larynx
trachea
bronchi
bronchioles
blood capillaries
larynx
rings of cartilage keep the trachea open
cilia
gas exchange by diffusion
large surface collectively; one cell layer thick; surfactant on interior of alveolus;
blood capillaries surrounding exterior of alveolus
facilitate diffusion, and prevent collapse of alveolus on exhalation
rib cage
diaphragm
pleural membranes
interpleural space
diaphragm contracts and flattens out; rib cage moves up and out
diaphragm relaxes and forms a dome; rib cage moves down and in
rising carbon dioxide levels
stretch receptors surrounding each alveolus are stimulated
falling oxygen levels

the hydrogen ions are grabbed by hemoglobin to form reduced hemoglobin
reduced hemoglobin gives up the hydrogen ions in order to grab oxygen from the
alveoli
buffer pH in the cells; neutralize acidic chyme from stomach; transport carbon
dioxide in the blood
if there is a hole in the thoracic cavity, air will rush into the thoracic cavity and
squeeze on the exterior of the lung, thereby preventing inhalation
