| DURING NORMAL INSPIRATION,____ PROGRESSIVELY STRETCH AND FLATTEN | ALVEOLAR VESSELS |
| ---THE RECRUITMENT AND DISTRENSION OF PULMONARY VESSELS WILL ENSUE, AND PULMONARY VASCULAR RESISTANCE WILL TEND TO DECREASE | BLOOD VOLUME CHANGES |
| ___IS DERIVED FROM THE HEMATOCRIT, THE INTERITY OF RED BLOOD CELLS, AND THE COMPOSITION OF PLASMA. AS___INCREASES, THE PULMONARY VASCULAR RESISTANCE INCREASES | BLOOD VISCOSITY CHANGES |
| THE TRANSPORT OF OXYGEN TO THE CELLS OF THE BODY IS A FUNCTION OF THE | CIRCULATORY SYSTEM |
| THE ESSENTIAL COMPONENTS OF THE CIRCULATORY SYSTEM CONSIST OF | BLOOD, HEART, AND THE PULMONARY AND SYSTEMIC VASCULAR SYSTEM |
| BLOOD CONSIST OF A VARIETY OF SPECIALIZED CELLS THAT ARE SUSPENDED IN FLUID CALLED | PLASMA |
| THE CELLS IN THE PLASMA INCLUDE | ERYTHROCYTES, LEUKOCYTES, THROMBOCYTES |
| ESSENTIAL COMPONENTS OF THE HEART INCLUDE THE RIGHT AND LEFT | ATRIA, VENTRICLES, AND THE INTERVENTRICULAR SEPTUM, PERICARDIUM |
| ESSENTIAL COMPONENTS OF THE HEART INCLUDE | THE WALLS OF THE HEART( EPICARDIUM, MYOCARDIUM, ENDOCARDIUM ) |
| ESSENTIAL COMPONENTS OF THE HEART INCLUDE | THE ARTERIAL SUPPLY OF THE HEART ( THE LEFT AND RIGHT CORORNARY ARTERY) THE VENOUS DRAINAGE ( THE GREAT CARDIAC VEINS, MIDDLE CARDIAC VEINS, CORONARY SINUS, AND THEBESIAN VEIN AND THE BLOOD FLOW THROUGH THE HEART |
| THE PULMONARY AND SYSTEMIC VASCUALRY SYSTEM ARE COMPOSED OF THE | ARTERIES, ARTERIOLES, ACAPPILLARIES, VENULES, VEINS |
| THE PULMONARY ARTERIOLES AND MOST OF THE ARTERIOLES IN THE SYSTEMIC CIRCULATION ARE CONTROLLED BY | SYMPATHETIC IMPULES |
| SPECIALIZED STRETCH RECEPTORS CALLED | BARORECEPTORS |
| THREE TYPES OF PRESSURES ARE USED TO STUDY THE BLOOD FLOW IN THE PULMONARY ADN SYSTEMIC VASCULAR SYSTEMS INCLUDE | INTRAVASCULAR, TRANSMURAL, AND DRIVING |
| DURING EACH CARDIC CYCLE THE ____AND ___HAVE A DIRECT RELATIONSHIP TO THE BLOOD PRESSURE | SYSTOLE AND DIASTOLE |
| DURING ___ THE ARTERIAL BLOOD PRESSURE SHARPLY INCREASES, DURING ____, THE ARTERIAL BLOOD PRESSURE DECREASES | VENTRICULAR SYSTOLE, VENTRICULAR DIASTOLE |
| THE HIGH AND LOW BLOOD PRESSURE GENERATED BY VENTRICULAR SYSTOLE AND DIASTOLE REULTS IN MEAN ____THROUGHOUT THE PULMONARY AND SYSTEMIC CIRCULATION | INTRALUMINAL BLOOD PRESSURE |
| THE MEAN ____PRESSURE IS ABOUT 10 TIMES THAT OF THE PULMONARY VASCULAR SYSTEM | SYSTEMIC VASCULAR |
| THE DISTRIBUTION OF PULMONARY BLOOD FLOW IS A FUNCITON OF ___- | 1. GRAVITY, 2. CARDIAC OUTPUT, 3. PULMONRY VASCULAR RESISTANCE |
| THE INFLUENCE OF GRAIVITY IN THE UPPER RIGHT LUNG IS DESCRIBED IN TERMS OF | ZONE 1,2, 3 IS THE MOST GRAVITY- DEPENDENT AREA |
| DETERMINANTS OF CARDIAC OUTPUT IS A FUNCTION OF | VENTRICULAR PRELOAD, VENTRICULAR AFTERLOAD, MYOCARDIAL CONTRACTILITY |
| THE PULMONARY VASCULAR RESISTANCE MAY INCREASE OR DECREASE AS A RESULT OF __AND __ | ACTIVE AND PASSIVE MECHANISMS |
| ACTIVE MECHANISMS INCLUDE | ABNORMAL BLOOD GASES, PHARMOLOGIC STIMULATION, PATHOLOGIC CONDIDITONS |
| PASSIVE MECHANISMS INCLUDE | INCREASED PULMONARY ARTERIAL PRESSURE, INCREASED LEFT ARTERIAL PRESSURE, LUNG VOLUME CHANGES, ADN BLOOD VOLUME AND BLOOD VISCOSITY CHANGES |
