Q

the percent fraction of formed elements relative to whole food is the

A

hematocrit

33
Q

the t wave on and ECG training represents

A

ventricular repolarization

34
Q

edema may occur when

A

the plasma concentration of protein is reduced, capillary hydrostatic pressure is elevated, and the capillary endothelium permeability goes up

the sequence in which excitation would move through this system is

A

4,3,2,5,1

37

A

is a component of the hypothalamus

42
Q

the function of hemoglobin is to

A

carry dissolved blood gases
