Functions of the Circulatory system
- –Transport
- •O2, CO2, nutrients, wastes, hormones, and stem cells
- –Protection
- •Inflammation, limit spread of infection, destroy microorganisms and cancer cells, neutralize toxins, and initiate clotting
- –Regulation
- •Fluid balance, stabilizes pH of ECF, and temperature control

4 to 6 L
-
Matrix of blood. Is clear, light yellow fluid
Plasma
-
Blood cells and cell fragments.

- 2. Platelets
- 3. Neutrophils (granulocyte)
- 4. Eosinophils (granulocyte)
- 5. Basophils (granulocyte)

The Values of centrifuged blood
Hematocrit
-
Are the heaviest and settle first in the hematocrit and are 37% to 52% total volume
Erythrocytes
-
Is 1% total volume is the buffy coat
White blood cells and platelets
-
Is the remainder of volume of hematocrit is 47% to 63%. Is a complex mixture of water, proteins, nutrients, electrolytes, nitrogenous wastes, hormones and gases
Plasma
-
Plasma is the liquid portion of blood. What is the remaining fluid when blood clots and the solids are removed?
Serum is identical to plama except for the absence of fibrinogen
-
What are the three major categories of plasma proteins?
- 1. Albumins
- 2. Globulins
- 3. Fibrinogen
-
Is the smallest and most abundant of plasma proteins. Contributes to viscosity and osmolarity; influence blood pressure, flow, and fluid balance
Albumins
-
(antibodies) provide immune system functions
Alpha, beta, and gamma _______? What plasma protein?
Globulins
-
Precursor of fibrin threads that help form blood clots is a plasma protein
Fibrinogen
-
Where are plasma proteins formed and what is the exception?
- •formed by liver
- –Except globulins (produced by
- plasma cells)
