THE RESPIRATORY SYSTEM
| Question | Answer |
|---|---|
| WHAT IS NOT A FUNCTIONAL PROCESS PERFORMED BY THE RESPIRATORY SYSTEM | TRANSPORT OF RESPIRATORY GASES |
| THE LOUDNESS OF A PERSONS VOICE DEPENDS ON THE | FORCE WITH WHICH AIR RUSHES ACROSS THE VOCAL CORDS |
| THE WALLS OF THE ALVEOLI ARE COMPOSED OF TWO TYPES OF CELLS, TYPE I AND TYPE II. THE FUNCTION OF THE TYPE II IS TO | SECRETE SURFACTANT |
| COMPLETE THE FOLLOWING STATEMENT: AIR MOVES OUT OF THE LUNGS WHEN THE PRESSURE INSIDE THE LUNGS IS | GREATER THAN PRESSURE IN THE ATMOSPHERE |
| UNLIKE INSPIRATION, EXPIRATION IS A PASSIVE ACT BECAUSE NO MUSCULAR CONTRACTIONS ARE INVOLVED. EXPIRATION HOWEVER DEPENDS ON TWO FACTORS. WHAT ARE THE TWO FACTORS | THE RECOIL OF ELASTIC FIBERS THAT WERE STRETCHED DURING INSPIRATION AND THE INWARD PULL OF SURFACE TENSION DUE TO THE FILM OF ALVEOLAR FLUID. |
| WHAT MAINTAINS THE PATENCY (OPENESS) OF THE TRACHEA | CARTILAGE RINGS |
| INTRAPULMONARY PRESSURE IS THE | PRESSURE WITHIN THE ALVEOLI OF THE LUNGS |
| THE RELATIONSHIP BETWEEN THE PRESSURE AND VOLUME OF GASES IS GIVEN BY | BOYLES LAW |
| THE STATEMENT " IN A MIXTURE OF GASES THE TOTAL PRESSURE IS THE SUM OF THE INDIVIDUAL PARTIAL PRESSURES OF GASES IN THE MIXTURE" PARAPHRASES | DALTONS LAW |
| SURFACTANT HELPS TO PREVENT ALVEOLI FROM COLLAPSING BY | INTERFERING WITH THE COHESIVENESS OF WATER MOLECULES THEREBY REDUCING SURFACE TENSION OF ALVEOLAR FLUID. |
| FOR GAS EXCHANGE TO BE EFFICIENT THE RESPIRATORY MEMBRANE MUST BE | 0.5 TO 1 MICROMETER THICK |
| WITH THE BOHR EFFECT MORE OXYGEN IS RELEASED BECAUSE A | DECREASE IN PH (ACIDOSIS)WEAKENS THE HEMOGLOBIN OXYGEN BOND |
| THE MOST POWERFUL RESPIRATORY STIMULUS FOR BREATHING IN A HEALTHY PERSON IS | INCREASE IN CARBON DIOXIDE |
| NERVE IMPULSES FROM ____ WILL RESULT IN INSPIRATION | THE VENTRAL RESPIRATORY GROUP |
| IN THE PLASMA THE QUANTITY OF OXYGEN IN SOLUTION IS | ONLY ABOUT 1.5% OF THE OXYGEN CARRIED IN DISSOLVED FORM. |
| WHICH OF THE FOLLOWING STATEMENTS IS CORRECT | RESPIRATORY RATE IS LOWEST IN NEWBORN INFANTS |
| WHAT BEST DESCRIBES THE FORCES THAT ACT TO PULL THE LUNGS AWAY FROM THE THORAX WALL AND THUS COLLAPSE THE LUNGS | THE NATURAL TENDANCY FOR LUNGS TO RECOIL AND THE SURFACE TENSION OF THE ALVEOLAR FLUID |
| WHAT DOES NOT INFLUENCE THE INCREASE IN VENTILATION THAT OCCURS AS EXERCISE IS INITIATED. | DECREASE IN LACTIC ACID LEVELS |
| WHAT IS NOT A FORM OF LUNG CANCER | KAPOSI SARCOMA |
| WHAT IS NOT AN EVENT NECESSARY TO SUPPLY THE BODY WITH O2 AND DISPOSE OF CO2 | BLOOD PH ADJUSTMENT |
| WHAT IS NOT TRUE ABOUT THE RESPIRATORY TRACT FROM THE MEDIUM BRONCHI TO THE AVEOLI | RESISTANCE TO AIR FLOW INCREASES DUE TO THE INCREASE IN CROSS SECTIONAL DIAMETER |
| WHAT DETERMINES LUNG COMPLIANCE | ALVEOLAR SURFACE TENSION |
| TIDAL VOLUME IS AIR | EXCHANGED DURING NORMAL BREATHING |
| WHAT DETERMINES THE DIRECTION OF RESPIRATORY GAS MOVEMENT | PARTIAL PRESSURE GRADIENT |
| POSSIBLE CAUSES OF HYPOXIA INCLUDE | TOO LITTLE OXYGEN IN THE ATMOSPHERE |
| THE LUNG VOLUME THAT REPRESENTS THE TOTAL VOLUME OF EXCHANGEABLE AIR IS THE | VITAL CAPACITY |
| BECAUSE THE LUNGS ARE FILLED WITH FLUID DURING FETAL LIFE WHAT STATEMENT IS TRUE REGARDING RESPIRATORY EXCHANGE | RESPIRATORY EXCHANGES ARE MADE THROUGH THE PLACENTA |
| WHAT IS NOT A STIMULUS FOR BREATHING | RISING BLOOD PRESSURE |
| RESPIRATORY CONTROL CENTERS ARE LOCATED IN THE | MEDULLA AND PONS |
| THE AMOUNT OF AIR THAT CAN BE INSPIRED ABOVE THE TIDAL VOLUME IS CALLED | INSPIRATORY RESERVE |
| WHICH STATEMENT ABOUT CO2 IS INCORRECT | MORE CO2 DISSOLVES IN THE BLOOD PLASMA THAN IS CARRIED IN THE RBC'S |
| OXYGEN AND CARBON DIOXIDE ARE EXCHANGED IN THE LUNGS AND THROUGH ALL CELL MEMBRANES BY | DIFFUSION |
| SELECT THE CORRECT STATEMENT ABOUT THE PHARYNX | THE AUDITORY TUBE DRAINS INTO THE NASOPHARYNX |
| THE LARYNX CONTAINS | THE THYROID CARTILAGE |
| WHICH RESPIRATORY ASSOCIATED MUSCLES WOULD CONTRACT IF YOU WERE TO BLOW UP A BALLOON | INTERNAL INTERCOSTALS AND ABDOMINAL MUSCLES WOULD CONTRACT |
| HOW IS THE BULK OF CARBON DIOXIDE CARRIED IN THE BLOOD | AS THE BICARBONATE ION IN THE PLASMA AFTER FIRST ENTERING THE RED BLOOD CELLS |
| WHAT IS NOT FOUND IN THE RIGHT LOBE OF THE LUNG | CARDIAC NOTCH |
| WHAT IS NOT A ROLE OF THE PLEURA | AIDS IN BLOOD FLOW TO AND FROM THE HEART BECAUSE THE HEART SITS BETWEEN THE LUNGS |
| WHAT CORRECTLY DESCRIBES THE MECHANISMS OF CO2 TRANSPORT | ATTACHED TO THE HEME PART OF HEMOGLOBIN |
| FACTORS THAT INFLUENCE THE RATE AND DEPTH OF BREATHING INCLUDE | VOLUNTARY CORTICAL CONTROL |
| WHAT PROVIDES THE GREATEST SURFACE AREA FOR GAS EXCHANGE | ALVEOLI |
| THE RESPIRATORY MEMBRANE IS A COMBINATION OF____ | ALVEOLAR AND CAPILLARY WALLS AND THEIR FUSED BASEMENT MEMBRANES |
| GAS EMBOLI MAY OCCUR BECAUSE | DIVER HOLDS HIS BREATH UPON ASCENT |
| INSPIRATORY CAPACITY IS | THE TOTAL AMOUNT OF AIR THAT CAN BE INSPIRED AFTER A TIDAL EXPIRATION |
| WHICH CENTER IS LOCATED IN THE PONS | PONTINE RESPIRATOR GROUP (PRG) |
| THE NOSE SERVES ALL THE FOLLOWING FUNCTIONS EXCEPT | AS THE INITIATOR OF THE COUGH REFLEX |
| A PREMATURE BABY USUALLY HAS DIFFICULTY BREATHING, HOWEVER THE RESPIRATORY SYSTEM IS DEVELOPED ENOUGH FOR SURVIVAL BY | 28 WEEKS |
| WHAT IS A TRUE STATEMENT REGARDING THE RESPIRATORY RATE OF NEWBORNS | THE RESPIRATORY RATE OF A NEWBORN IS AT ITS HIGHEST RATE APPROXIMATELY 40-80 RESPIRATIONS PER MINUTE |
| WHAT IS A CORRECT STATEMENT ABOUT NEURAL MECHANISMS OF RESPIRATORY CONTROL | THE PONS IS THOUGHT TO BE INSTRUMENTAL IN THE SMOOTH TRANSITION FROM INSPIRATION TO EXPIRATION |
| WHAT IS NOT A FACTOR THAT PROMOTES OXYGEN BINDING TO AND DISSOCIATION FROM HEMOGLOBIN. | NUMBER OF RED BLOOD CELLS |
