00:30 Percent Complete 100% iRespond Question Master A.) Response A B.) Response B C.) Response C D.) Response D E.) Response E Components of Blood What are the parts of blood? 1. 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 • Total blood volume -adult males= 5-6 Liters -adult females= 4-5 Liters -American Red Cross Donations -Restrictions? -Hematopoesis Hem=? Poesis=? Why the discrepancy? 2. Erythrocytes– AKA-red blood cells – Biconcave cellslarger 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 groups1. Granulocytes- cells which have a grainy cytoplasm 2.Agranulocytes- cell which do not have a grainy cytoplasm There are 5 Types of WBCs: Granulocytes1-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: Agranulocytes4-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 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. ThrombocytesHemostasis- 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 • https://www.youtube.c om/watch?v=vEmsaXAgo0 • https://www.youtube.c om/watch?v=JvOH5skx qoA • https://www.youtube.c om/watch?v=M_YpLaW dBpk https://www.youtube.com/watc h?v=-JerRPgnVGs
