Lab 3 Blood Cells & Blood Typing

Blood Contents Centrifuged blood Plasma = 55% Blood Cells = 45%

Red Blood Cell = Erythrocytes Diameter = 7-7.5micrometers Biconcave Anucleated Contains Hemoglobin Transports gas (O2 and some CO2) Oxygenated= bright red Deoxygenated = brick red/brown

RBC Counts Million cells per mm3 Men = 4.6 - 6.2 Women = 4.2 - 5.4 Children = 4.5 - 5.1

Agranulocytes Granulocytes White Blood Cells 5,000-10,000 cells per mm3 Agranulocytes Granulocytes Neutrophil (54-62%) Eosinophil (1-3%) Basophil (<1%) Lymphocyte (25-33%) Monocyte (3-9%)

Lympocyte

Neutrophil Monocyte

Basophil

Eosinophil

Platelets = 130,000-360,000 cells per mm3

Blood Testing 1 = Coagulation Time Normal = 2-6 minutes 2 = Hematocrit Women = 37-47% Child = 35-49% 3 = Hemoglobin Content Men = 14-18 grams/100mL Women = 12-16 grams/100mL Child = 11-16.5 grams/100mL

Blood Typing

A B Rh Type = A negative
