Purpose of CV system.
- Provide O2 and nutrients.
- Removal of CO2 and waste.
- Transports hormones from site of production to site of action.
- Part of immune system.
- Involved in temperature regulation.
- Involved in the regulation of fluid volume.
Define hematocrit.
Percent by volume of RBC.
Define portal system.
Flow from artery to capillary to second collecting vessel to a second capillary bed, and then to the venous system.
Compare and contrast content vs. concentration.
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)
CO and percent blood flow through the right heart at rest.
CO=5.5 L/min
Blood flow=100%
CO and percent blood flow through the left heart with exercise.
CO=25 L/min
Blood flow=100%
Volume of blood and the percent of total CO that goes to the brain at rest and during exercise.
-At rest:
Volume: 830 mL
% Total CO: 13-15%
-Exercise
Volume: 880 mL
% Total CO: 3-4%
Volume of blood and the percent of total CO that goes to the heart at rest and during exercise.
-At rest
Volume: 280 mL
% CO: 4-5%
-Exercise
Volume: 1,100 mL
% CO: 4-5%
