Cardio, Respiratory, Immunity
| Question | Answer |
|---|---|
| Neutrophil | 50-70%, phagocytosis |
| Eosinophils | 2-4%, detoxify foreign substances, secrete enzymes that dissolve clots, fight parasitic infections |
| Basophils | less than 1%, release anticoagulant heparin |
| Lymphocytes | 20-30%, provides specific immune response, including antibodies |
| Monocytes | 2-8%, Phagocytosis |
| Eupnea | normal respiratory rate & depth, normal total minute volume exchange |
| Apnea | temporary cessation of breathing |
| hyperventilation | increased ventilate rate does not match metabolic needs, caused by sympathetic nervous system & results in decreased co2 and increased pH |
| hyperpnea | increased total minute volume during exercise, blood co2 levels do not change because increased ventilation matches metabolic demands |
| anoxia | deprivation of oxygen to the point of tissue dammage |
| tachypnea | excessive or rapid breathing rate, not associated with metabolic demands |
| hypercapnia | excessive concentration of carbon dioxide in blood |
| dyspnea | subjective difficulty in breathing |
| asphyxia | unconsciousness or death resulting from lack of oxygen |
| Vital capacity | total amount of air forcibily exhaled following maximal inhalation |
| total lung capacity | total amount of air in lungs after a maximal forced inspiration |
| inspiratory capacity | total amount of air that can be forcibly inspired |
| functional residual capacity | volume of gas remmaining within lungs after a normal tidal expiration |
| Rhythmicity center | loose aggregation of neurons in reticular formation of the medulla, controls autonomic breathing |
| apneustic center | promote sinspiration by stimulating the neurons in medulla |
| pneumotaxic center | antagonizes the apneustic center & inhibits inspiration |
| pulse pressure | systole- diastole |
| mean arterial pressure | diastolic + 1/3 pulse pressure |
| chronotropic | rate |
| inotropic | contraction |
| cholinergic | related to ach |
| adrenergic | receptors activated by epinephrine |
| agonistic | type of drug that binds and alters activity of a receptor |
| antagonistic | consequence of one chemical counteracting the effects of another, blocks or opposes |
| sympathomimetic drug | mimics epinephrine and dopamine |
| parasympathomimetic drug | mimics ach, pilocarpine & nicotine |
| parasympatholytic drug | blocks parasympathetic activity, so speeds up, atropine |
| hyperkalemia | elevated potassium |
