Blood Cells

QuestionAnswer
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
