Spirometry
A single normal inhalation.
tidal volume
S1 heart sound corresponds to the closing of these valves.
AV valves
What does an increase in resistance do to blood flow?
Decreases
chordae tendineae
hematocrit
Air left in the lungs after a full exhalation.
Residual volume
This valve opens when left ventricular pressure is high enough.
aortic semilunar
What does an increase in resistance do to blood pressure?
Increases
Left coronary artery branch that runs to the left under the left atrium.
circumflex branch
The iron-containing porphyrin ring.
heme
TLC - RV
vital capacity
This part of the atrial pressure curve occurs during the end of ventricular diastole.
length of blood vessel
The first branch off of the aortic arch.
brachiocephalic artery (trunk)
Blood cell production.
hematopoeisis
TV + IRV
inspiratory capacity
T wave represents this electrical event in the heart.
ventricular repolarization
An increase in total cross sectional area has what effect on blood flow velocity?
decreases
Adult remnant of the foramen ovale.
Fossa ovalis
Plasma without clotting factors.
Serum
ERV + RV
functional residual capacity
Period before the AV valve opens; during diastole
isovolumic relaxation
The most important local vasodilator substance.
adenosine
Last part of the respiratory tree that is NOT capable of gas exchange.
terminal bronchiole.
Oxygenation of blood in the lungs displaces carbon dioxide from hemoglobin.
Haldane effect
