Non protein nitrogen containing compounds- urea, creatinine
Nutrients- glucose, lipids, AA
Gases
Hormones, enzymes
What is the amount of cellular components of the blood?
Hematocrit
What has about 99% erythrocytes and 1% leukocytes?
Hematocrit
What are the 3 things that can cause differences in hematocrit values?
Number or size of RBC
Nutrition, physical activity, metabolic rate
Altitude
What is the increased hematocrit during physical activity mainly due to?
Increased sympathetic nervous system activity
Where (2 places) does the sympathetic versus system activity mobilize erythrocytes from?
Spleen and other parts of cardio system
Which blood cells are circular, flattened, bi-concave with a thin middle part surrounded by thicker periphery?
RBC
Which cell is NON-nucleated and has NO mitochondria?
RBC
Which blood cell has the function to transport oxygen away from the lungs to the cells of the body by means of hemoglobin and to remove CO2 from the tissues?
RBC
What are the 3 things that are essential for the function of RBCs?
Number, shape, Hb concentration
