Chapter 9
| Term | Definition |
|---|---|
| neutrophils | white blood cell- first responders (most prominent) |
| lymphocytes | white blood cell- offer better long term immunity to disease |
| monocytes | white blood cell- stimulate fibroblasts, scar tissue |
| eosinophils | white blood cell- responds to infection w/ multicellular parasites & also during allergic reactions |
| basophils | white blood cell- respond to areas of injury and release histamine & heparin (increase inflammation) |
| right atrium | upper right chamber, collects blood returning from the body tissues. Gets blood from the superior & inferior vena cava |
| right ventricle | lower chamber right side, ejects deoxygenated blood to the lungs via the pulmonary trunk & arteries |
| left atrium | upper chamber left side, receives oxygenated blood from the pulmonary veins of the lungs |
| left ventricle | lower left chamber, pumps blood out to the tissues via aorta |
| right atrioventricular valve tricuspid valve | separates right atrium & right ventricle (lub) |
| pulmonary valve pulmonary semilunar valve | one way valve prevents backflow between right ventricle and pulmonary trunk (dub) |
| left atrioventricular valve bicuspid or mitral valve | prevents backflow between left atrium & ventricle (lub) |
| aortic valve aortic semilunar valve | one way valve prevents backflow between left ventricle & ascending aorta (dub) |
| systole | when the heart chambers are contracting & ejecting blood. TOP number of BP |
| diastole | when the heart chambers are relaxing & refilling. BOTTOM number of BP |
| stroke volume | amount of blood ejected by the heart in one cardiac cycle |
| cardiac output | measures the amount of blood ejected from the ventricles in one minute |
