Question 15

Define hematocrit.

Answer 15

Percent by volume of RBC.

Question 16

Define portal system.

Answer 16

Flow from artery to capillary to second collecting vessel to a second capillary bed, and then to the venous system.

Question 17

Compare and contrast content vs. concentration.

Answer 17

Content: the actual level that you have, ex: mL/volume
Concentration: the percent of saturation (the percent you have/carrying capacity). Recorded in mL % or (mL of __/100 mL)
