Cards

Term
pulse pressure (pp)
Definition
systolic - diastolic pressure
Term
mean arterial pressure (map)
Definition
diastolic pressure + 1/3 pulse pressure (pp)
Term
stroke volume (sv)
Definition
pulse pressure x 1.7
Term
cardiac output (co)
Definition
stroke volume x heart rate = cardiac output ml/min
Term

P wave 

 

Definition
atrial depolarization
Term
qrs complex
Definition
ventricular depolarization
Term
t wave
Definition
ventricular repolarization
Term
lub sound
Definition
av valves closing
Term
dup sound
Definition
semilunar valves closing
Term
hematopoiesis
Definition
process of red blood cell production, in the red bone marrow
Term
blood plasma constituents
Definition
mostly water, albumin, fibrinogen, and globulins
Term
erythropoietin
Definition
hormone that regulates red blood cell production, secreted from the kidneys to signal the red bone marrow to begin production
Term
serum
Definition

blood plasma without clotting agents (fibrinogen, etc.)

Term
hemoglobin
Definition
oxygen carrying protein, constitutes majority of red blood cell make-up
Term
Antibody
Definition
Y shaped protein with binding sites for antigens, lock/key mechanism either disrupts the microbe / affected cell directly or tags it for recognition by other parts of the immune system
Term
hemostasis
Definition
cessasion of bleeding
Term
coagulation
Definition
process in which blood forms clots, uses platelets and fibrin
Term
Anemia
Definition
condition of decreased numbers of erythrocytes, or low hemoglobin content in the blood
Term
polycythemia
Definition
too many erythrocytes
Term
leukocytosis
Definition
increased white blood cell count
Term
leukopenia
Definition
decrease in WBC count in the blood
Term
thrombocytosis
Definition
increase number of platelets
Term
thrombocytopenia
Definition
low platelet count
Term
tidal volume
Definition
normal breathing range
Term
inspiratory reserve volume
Definition
air intake capacity above tidal volume
Term
expiratory reserve volume
Definition
amount of air volume one can force from their lungs below tidal volume
Term
residual volume
Definition

amount of air volume that cannot be forced out of the lungs under normal conditions

 

estimated to be 1200cc for males, 900cc for females

Term
inspiratory capacity
Definition

volume one is able to take in after a normal "tidal" exhale

 

in other words from the bottom of the tidal volume range up to full capacity

Term
vital capacity
Definition
total lung capacity - residual volume
Term
total lung capacity
Definition
entire volume capacity of lungs
Term
functional residual capacity
Definition

total volume remaining in lungs during a normal exhale

 

in other words, from the bottom of tidal volume down, including residual volume, or ERV + RV
