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 |
