Fetal pig, circulatory, respiratory, and urinary

_______________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
