| Question | Answer |
|---|---|
| _______________transport oxygen. they are disc shaped cells which lack a nucleus and are smaller and more numerous than white blood cells. | Erythrocytes (red blood cells) |
| ___________________fight infection. they are large cells containing a nucleus. there are 5 types: neutrophils, eosinophils, basophils, monocytes and lymphocytes | Leukocytes (white blood cells |
| _____________mostly water with dissolved proteins, nutrients, minerals, hormones and waste products | plasma |
| _______________are important for clotting. ____________are cell fragments that lack a nucleus and are very thin | Thrombocytes, Platelets |
| blood pressure is a measure of the heart's pumping ability and the __________________ of the arteries | elasticity |
| blood pressure measured when the heart is contracting is called the _______________ pressure and when the heart is relaxing is called the ________________ pressure | systolic, diastolic |
| the measurement is given in ________________ with the systolic pressure over the diastolic pressure | millimeters of mercury |
| ____________________(blood pressure cuff) | sphygmomanometer |
| the valves in large veins keep the blood flowing towards the _______________ | heart |
| the ECG is a reading of the flow of ___________________ current through the wiring system of the heart | electrochemical |
| the electrochemical current moving through the conduction system of the heart causes the _______________ and ______________ of the heart to contract(systole) and relax (diastole) in a rhythmic manner | Atria, ventricles |
| each time the current moves across the heart, it generates a characteristic pattern when recorded by an _____________________ | electrocardiograph |
| ________________-atrial excitation and the beginning of atrial systole; ________________- ventricular excitation and beginning of ventriclar systole; the atria relax (diastole) during this time. _________________ ventricular diastole | P-wave, QRS complex, T-wave |
| changes or differenece in the ECG from normal may represent a __________ process, a past injury to the heart (such as myocardial infarction), or some changes maybe caused by certain medications | disease |
| the number of ECG patterns in one minute equals the ___________________ | heart rate |
| measurement of the __________________provides a tool for understanding normal function of the lungs as well as disease states. | lung volumes |
| _______________of the diaphragm causes it to flatten downward | contraction |
| __________________is passive, resulting from "recoil" of the chest wall, diaphragm, and lung tissue | normal exhalation |
| in normal breathing at rest, approximately ____________ of the total lung capacity is used. | one-tenth |
| _______________the volume of air breathed in and out without conscious effort | tidal volume |
| ________________the additional volume of air that can be inhaled with maximum effort after a normal inspiration | inspiratory reserve volume (IRV) |
| ________________the additional volume of air that can be forcibly exhaled after normal exhalation | expiratory reserve volume (ERV) |
| ________________the total volume of air that can be exhaled after a maximum inhalation | vital capacity (VC) |
| VC= __________ + ___________ + __________ | TV+IRV+ERV |
| ___________________the volume of air remaining in the lungs after maximum exhalation (the lung can never be completely emptied_ | residual volume(RV) |
| _________________= VC + RV | Total lung capacity (TLC) |
| _________________ the volume of air breathed in 1 minute | minute ventilation |
| when proforming called specific gravity what do you use? _________________ | hydrometer |
