What effect does exercise have on BP and pulse rate?
It increases pulse rate and decreases BP
Inhalation?
atmospheric air pressure is HIGHER than air pressure in the lungs
Exhalation?
atmospheric air pressure is LOWER than air pressure in the lungs
veins carry ______ blood
deoxygenated (blue)
arteries carry _________ blood
oxygenated (red)
where does the systemic circuit send blood?
throughout the entire body
where does the pulmonary circuit send blood?
sends blood to lungs which gains oxygen
order of pulmonary circuit:
inferior/superior vena cava, right atrium, bicuspid valve, right ventricle, pulmonary semilunar valve, pulmonary arteries, lungs, pulmonary veins (high o2), left atrium (high o2)
order of systemic circuit:
pulmonary veins, left atrium, tricuspid valve, left ventricle, aortic semilunar valve, aorta, arteries, arterioles, capillaries, venules, veins, inferior vena cava
where does gas exchange take place?
capillaries
TV
tidal volume = amount of air in/out during normal breathing
IRV
inspiratory reserve volume = amount of air inhaled after normal inhalation
ERV
expiratory reserve volume = amount of air exhaled after normal exhalation
residual volume
amount of air always in lungs (think residual like resident)
vital capacity
max air in/out of lungs
(TV + IRV + ERV)
total lung capacity
max air lungs can hold
