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
