| Question | Answer |
| total lung capacity (equation) | inspiratory reserve + tidal + expiratory reserve + residual |
| vital capacity (equation) | inspiratory reserve + tidal + expiratory reserve |
| functional residual capacity (equation) | reserve + expiratory reserve |
| inspiratory capacity (equation) | inspiratory reserve + tidal |
| tidal volume | air inhaled per breath |
| inspiratory reserve | amt inspired beyond normal breathing |
| expiratory reserve | max amt expired during normal breathing |
| residual volume | amt air left after maximal expiratory effort |
| BTPS | body temp ambient pressure saturated gas |
| hyperventilation results in | no change in blood oxygen |
| Haldane-Priestly | estimate pulmonary capillary levels of CO2; blood gases in eq |
| FECO2 number | 0.03 to 0.05 |
| FEO2 number | 0.16 to 0.17 |
| oxygen consumption measurements are converted to | STPD |
| Haldane measurements | FECO2, FEO2, VE |
| oxygen consumption | total oxygen utilized per unit time |
| heat production | total heat produced per unit time |
| metabolic rate (humans) | kcal/m2*hr |
| metabolic rate (all species) | volume/time or kcal/time |
| metabolic intensity | volume O2/(time*kg) or kcal/time*kg |
| means of excitation for cardiac muscle | pacemaker cells |
| SA node innervated by | both autonomic systems |
| AV node innervated by | both autonomic systems |
| atria innervated by | both autonomic systems |
| ventricles innervated by | sympathetic only |
| shallowest prepotential slope | ventricles |
| intermediate prepotential slope | atria |
| steepest prepotential slope | sinus venosus |
| MAP= | cardiac output x peripheral resistance (sys-dias)/+dias |
| CO= | SV x HR |
| venoconstriction | systolic |
| vasoconstriction | diastolic |
| three mechanisms that get blood from heart to extremities | skeletal muscle pump, thoracic pump, venoconstriction |
| what is the effect of venoconstriction on venous return | increases |
| effect of venodilation on venous return | decreases |
| three factors that alter peripheral resistance | viscosity length diameter |
| does systolic pressure change with vasoconstriction | systolic pressure increases |
| during moderate exercise, diastolic BP ___, systolic BP ___ | decreases or remains same, increases |
