| Question | Answer |
| A type of breathing characterized by gradually increasing tidal volume for several breaths followed by several breaths with gradually decreasing tidal volume is | Cheyne-Stokes respiration. |
| The PCO2 in alveolar air is _______ blood. | -less than in the systemic venous - equal to the systemic arterial -Both A and C are correct |
| Which of the following would have the greatest accelerating effect on the dissociation of oxygen from hemoglobin? | Decreased PO2 and increased PCO2 |
| Which muscles are used for forced expiration? | Abdominal muscles and internal intercostals |
| The vital capacity is equal to the sum of the: | inspiratory reserve volume, tidal volume, and expiratory reserve volume |
| If the tidal volume of a given individual is 500 ml, then the anatomical dead space is approximately ___ ml. | 150 |
| The symbol HbNCOOH- is used for | carbaminohemoglobin. |
| Normal, quiet breathing is known as: | eupnea. |
| If a person were skiing high up in the mountains, she might feel that she is having trouble breathing (getting enough oxygen in her blood). This is because the: | lower atospheric pressure lowers the PO2 and the diffusion gradient between the blood and the atmosphere is less. |
| When the pressure in the lung is greater than atmospheric pressure: | expiration occurs. |
| A drop in the body's production of carbonic anhydrase would hinder the formation of: | carbonic acid. |
| By the time the blood leaves the lungs capillaries to return to the heart, what percentage of the blood's hemoglobin has united with oxygen. | 97% |
| Carbon dioxide is carried in three forms in the blood. Ranking them from greatest to least amount carried, the sequence would be: | bicarbonateion, carbaminohemoglobin, and dissolved in plasma |
| Excessive fluid in the pleural cavity would be most likely to cause | decreased vital capacity |
| Which type of breathing is characterized by repeated sequences of deep gasps and apnea, and is usually seen in people with increased intracranial pressure? | Biot's breathing |
| The PCO2 in the atosphere is | less than in the alveolar air |
| During inspiration, the expansion of the lungs causes | a decrease in alveolar pressure |
| One hundred millimeters of arterial blood contains approximately what volume percent of oxygen? | 20% |
| The major form by which carbon dioxide is transported in the circulatory system is | as bicarbonate ions. |
| Vital capacity is defined as the | maximum volume of air that can be moved into and out of the lungs during forced respiration. |
| The term used to describe the volume of air exchanged during normal inspiration and expiration is | tidal volume. |
| Which of the following is not a regulated process associated with the functioning of the respiratory system? | Control of cell metabolism rate |
| The approximate partial pressure of oxygen at standard atmospheric pressure is about _______mm Hg. | 160 |
| Dalton law states that the partial pressure of a gas mixture of gases is ________ to the total pressure of the mixture. | directly related to the concentration of that gas in the mixture and |
| Which of the following is not a means of transporting oxygen in the blood? | Combined with the bicarbonate ion (HCO3-) |
| Boyle's law states that volume of a gas varies __________ with pressure at a ____________ temperature. | inversely: constant |
| Standard atmospheric pressure is ______ mm Hg. | 760 |
| Which of the following helps determine the amount of oxygen that diffuses into the blood each minute? | All of the above help determine the amount of oxygen that diffuses into the blood each minute |
| Which of the following constitutes total lung volume? | Residual volume and vital capacity |
| About 98.5% of the oxygen carried by systemic arterial blood is attached to | hemoglobin. |
