| Term | Definition |
| General functions of blood. | Transportation- of gasses, nutrients, waste, and hormones
regulation- pH, Body temp, Water content of cells
Protection- WBC fight off disease |
| 6 Characteristics of Blood | color-
volume- 4-5(female) 5-6(male)
viscosity
plasma concentration- 0.09%
Temperature- 100.4
pH- 7.35-7.45 |
| Arteries | Transports blood away from the heart |
| Veins | transport blood towards the heart |
| Capillaries | allow exchange between blood and body tissues |
| Centrifuged blood | plasma(55% of whole blood)
Buffy coat(<1%of whole blood)
Erythrocytes(44% of whole blood) |
| Plasma (55% of whole blood) | Water
Proteins- Albumins, Globulin, fibrinogen, and regulatory proteins
other solutes- electrolytes, nutrients, respiratory gases, and waste products |
| Buffy coat(<1% of blood) | Platelets-150-400 thousand per cubic mm
Leukocytes - 4.5-11 thousand per cubic mm
Neutrophils ,lymphocytes, Eosinophils, Basophils, Monocyte |
| Erythocytes (44% of whole blood) | 4.2-6.2 Million per cubic mm |
| Hematocrit | Percentage of volume of all formed elements
Clinical Definition- Percentage of only erythrocytes |
| Blood Smear | Thin layer of blood placed on microscope slide and stained |
| Plasma Proteins | Albumins, Globulins, Fibrinogen, and Regulatory proteins |
| Albumins | Exerts osmotic force to retain fluid within the blood, contributes to blood's viscosity and is responsible for some fatty acid and hormone transport, |
| Globulins | Alpha-Globulins transport lipids and some metal ions
Beta-Globulins transports iron and lipids in blood
Gamma-Globulins are antibodies that immobilize pathogens |
| Fibrinogen | Participates in blood coagulation (Clotting) |
| Colloid | Blood is a colloid; Plasma contains dispersed proteins |
| Colloid osmotic pressure | Plasma proteins exert colloid osmotic pressure
-Prevents loss of fluid from blood as it moves through capillaries |
