Components of Blood

What are the parts of blood? Plasma- Clear, yellow colored liquid Makes up 55% Contains water (~90%) and solutes (~10%) -Amino acids, proteins, carbs, sugars, ions, electrolytes, and wastes, hormones

Plasma (cont.) ~45% remainder is Hematocrit /Blood cells -American Red Cross Donations -Restrictions? -Hematopoesis Hem=? Poesis=? Total blood volume -adult males= 5-6 Liters -adult females= 4-5 Liters Why the discrepancy?

2. Erythrocytes- AKA-red blood cells Biconcave cells-larger surface area Contain hemoglobin Lack a nucleus Mid-sized Most numerous cell in the blood Fxn-transport Oxygen and Carbon Dioxide

3. Leukocytes (see pg. 658 in Marieb) AKA-white blood cells All Larger than RBCs Least numerous cells in the blood Contains nucleus Fxn: fight disease

3. Leukocytes Broken into two groups- Granulocytes- cells which have a grainy cytoplasm Agranulocytes- cell which do not have a grainy cytoplasm

There are 5 Types of WBCs: Granulocytes- 1-Neutrophils-use phagocytosis (contain many lysosomes) on Bacteria 2-Eosinophils-use phagocytosis to engulf parasitic worms, control inflammation and allergic rxns, bilobed nucleus 3--Basophils-help with blood clotting (heparin), histamine-allergic reactions

There are 5 Types of WBCs: Agranulocytes- 4-Monocytes-use phagocytosis to engulf large invading organisms (macrophages) 5-Lymphocytes-major immunity cell, produce antibodies T-lymphocytes- attack infected cells B-lymphocytes- produce antibodies

Portions of very large cells ½ size of RBC WBC <# < RBC 4. Thrombocytes- AKA-platelets Portions of very large cells ½ size of RBC WBC <# < RBC FXN-stop blood flow forming a platelet plug Summary clip

4. Thrombocytes- Hemostasis- stopping of blood flow at a damaged tissue Coagulation- formation of a blood clot, platelets release chemicals which will assist in the coagulation, also assisted by protein fibrinogen] Summary clip
