Chapter 19 The Blood

Hematocrit

Substances in Blood Plasma Water Albumins Globulins Fibrinogen Electrolytes Nutrients Gases Regulatory substances Waste products

Red Blood Cell Production Terms Hemopoiesis Erythropoietin – secreted by kidneys Erythropoiesis Hypoxia Polycythemia

Hemoglobin

RBC Regulation

Types of WBC’s Granular and Agranular

Functions of WBC’s Neutrophils – Phagocytosis using lysozymes, defensins, and oxidants. Eosinophils - destroy parasites and combat histamines. Basophils – release heparin, histamine, and serotonin. Monocytes – Phagocytosis, clean cellular debris. Lymphocytes – B-cells, T-cells and NK-cells.

Diapedesis of WBC’s

WBC Terms Leukocytosis – above normal Leukopenia – below normal Phagocytosis Differential count

Platelet Plug

Blood clot

Platelet Terms Thrombopoietin Thrombocyte Hemostasis Anticoagulants (Heparin & Warfarin) Thrombus Embolus Thrombocytopenia

Clotting cascade

Blood Types

Rh Factor

Anemias Iron deficiency Pernicious ( Low B 12 ) Hemorrhagic Hemolytic Thalassemia Aplastic (loss of marrow)

Sickle Cell

Words to Know Hemophilia Leukemia Autologous transfusion Cyanosis Hemochromatosis Jaundice Septicemia
