Function of Blood 1. transporting nutrients, oxygen & hormones 2. removing metabolic wastes and CO 2 3. providing immunity (resistance to disease) through antibodies 4. maintaining body temperature and electrolyte balance 5. clotting to prevent bleeding from a wound

Blood § Blood divides into solid and liquid portions when spun in a centrifuge § Solid parts are called formed elements § Erythrocytes - Red blood cells (RBC’s) § Leukocytes - White blood cells (WBC’s) § Thrombocytes – platelets § The remaining liquid is composed of the buffy coat (mixture of WBC’s and platelets) and plasma

Blood and Blood cells § Plasma § Pale yellow fluid portion of blood § Make up 90% H 2 O, 10% protein § Contains special proteins that help blood to clot § Contains carbohydrates, proteins gases, hormones, enzymes, minerals, and waste products

Granulocytes § Neutrophils - engulf & digest bacteria called phagocytosis § Basophils - contain the anticoagulant substance heparin and participate in the inflammatory response § Eosinophils – defend the body from allergic reactions and parasitic infections
