| Question | Answer |
|---|---|
| Blood Cell Types | Erythrocyte, Thrombocyte, Neutrophil, Eosinophil, Basophil, Monocyte, B Lymphocyte, Cytotoxic T Lymphocyte, Helper T Lymphocyte |
| Erythrocyte | Function: CO2 and O2 transport |
| Thrombocyte | Function: Blood Clotting |
| Neutrophil | Function: Phagocytosis |
| Eosinophil | Function: Parasite Defense |
| Basophil | Function: Histamine release and other inflammation mediators |
| Monocyte | Function: Cellular debris and foreign invader removal |
| B Lymphocyte | Function: Antibody production |
| Cytotoxic T Lymphocyte | Function: Kill viral infected cells |
| Helper T Lymphocyte | Function: Stimulate B and T cell activity |
| Path Blood Takes Through the Heart | Superior/Inferior Vena Cava -> Right Atrium ->Tricuspid Valve -> Right Ventricle -> Pulmonary Semilunar Valve -> Pulmonary Arteries -> Lungs -> Pulmonary Veins -> Left Atrium ->Bicuspid Valve -> Left Ventricle -> Aortic Semilunar Valve -> Aorta |
| Veins | Blood vessel that contains valves to prevent backflow of blood Carry blood toward the heart |
| Blood Pressure | Force of the blood on the vessel walls |
| Arteries | Carry blood away from the heart Have thicker walls than veins |
| Capillary Vessels | Found at the junctions of arteries and veins Have only the layer of epithelium Allows vessels to act as sites of exchange for oxygen, carbon dioxide, nutrients, and wastes between tissue and blood |
| Blood Vessels | 3 Layers: Connective tissue, smooth muscle, endothelium tissue Veins and Arteries |
