Question
Answer
What are the 3 types of Blood Cells?   Thrombocytes, Erythrocytes, Leukocytes  
What is the definition of Thrombocytes?   Bone marrow cell fragments; non-nucleated  
What are the functions of Thrombocytes?   contain and release Serotonin and various clotting factors  
What is the function of the Serotonin released from Thrombocytes?   local Vasoconstrictor  
What do Erythrocytes look like?   Biconcave discs; non-nucleated  
Where are Erythrocytes formed?   Red Bone Marrow; stimulated by Erythropoietin from the Kidney  
What is the function of Erythrocytes?   carry Hemoglobin - molecule for O2 and CO2 transport  
What are the types of Granular Leukocytes?   Eosinophils, Basophils, Neutrophils  
Where are Granular Leukocytes formed?   develope and reproduce in Red Bone Marrow  
What is the function of Neutrophils, and what typr of Leukocyte are they?   PHAGOCYTOSIS of Bacteria and foreign material  
What is the function of Eosinophils, and what typr of Leukocyte are they?   DESTROY Multi-cellular Parasites  
What is the function of Basophils, and what typr of Leukocyte are they?   involved in INFLAMMATORY reponses; release Histamine & Anticoagulants  
What are the types of Agranular Leukocytes?   Lymphocytes, Monocytes  
What are the types of Lymphocytes?   T-cells, B-cells, NK-cells  
Where are Agranular Leukocytes formed?   in Red Bone Marrow - some mature and proliferate in Lymphoid Tissues  
What are the functions of T-cells?   destroy Virus Infected Cells, Tumors, and Tissue Transplants bearing foreign Antigens - effective against INTRAcellular Microbes  
What are the functions of B-cells   when exposed to foreign Antigens, they develop into Plasma Cells --> Antibodies - effective against EXTRAcellular Microbes  
What are the functions of NK-cells?   bind to and Chemically destroy Virus-Infected Cells and Tumors  
What do Monocytes develop into?   Macrophages  
What are the functions of Monocytes?   PHAGOCYTIZE Bacteria and Cell Debris help initiate T-cell action  
What part of blood is responsible O2/CO2 transport?   RBC, Plasma  
What part of blood is responsible for Nutrient, Waste, Lipid transport?   Plasma  
What part of blood is responsible for Thermoregulation?   Blood as a unit - Vasoconstriction, Vasodilation  
What part of blood is responsible for Hormone Transport?   Plasma  
What part of blood is responsible for Immune responses?   Leukocytes --> B-cells
