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 |
