| 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 |
