Question
For each of the following statements, fill in the blank with the appropriate scientist. During expiration in mammals. If a healthy young woman takes 12 breaths per minute with a tidal volume of 500 ml. what is her Total Pulmonary Ventilation Rate (in ml/min)? If a healthy female is breathing at 10 breaths per minute with a tidal volume of 600 ml. what is her Alveolar Ventilation Rate (in ml/min)? (assume a deadspace volume of 150 ml) A healthy young woman is breathing at 12 breaths per minute with a tidal volume of 500 ml. Which of the following statements is correct if she changes her breathing pattern to 15 breaths per minute with a tidal volume of 400 ml? (assume a dead space volume of 150 ml) During breathing in humans, which of the following does NOT contribute to Vital Capacity? At sea level, air pressure is 760 mm Hg and the partial pressure of oxygen is mm Hg. At higher elevations, air pressure is reduced, and the partial pressure of oxygen is (lower / the same / higher). even though the percent of oxygen in the air is Use the figure below to answer questions 8-10. If the partial pressure of oxygen were 60mm Hg. what percent of the binding sites on the hemoglobin would be occupied by oxygen? At what partial pressure of oxygen, in mm Hg. would the average hemoglobin molecule be bound to two O_2 molecules?Explanation / Answer
1.
Benjamin Franklin disocvered that an animal lives longer in presence of living vegetation.
Joseph Preistly invented carboanted water.
Antoine Lavoisier is credited with discovering that air contains a substance that is equal to maintain life and combustion.
Robert Boyle discovered that amount of heat produced relative to oxygen uptake is the same for living animals and burning coal.
2. During expiration in mammals: intra alevolar pressure is greater than atmospheric pressure.
The process of expiration occurs due to an elastic recoil of the lungs which results in decrease in volume and cause raise in pressure as compared with exteranl atmosphere; consequantly, air expire out of the lungs.
3.
Resting tidal volume = 500ml/breath
resting respiration rate = 15 breath/min
given respiration rate = 12 breath/min
Hence, total pulmonary ventilation rate (VE) = tidal volume (ml/breath) X respiratory rate (breath/min) = 500 X 12 total pulmonary ventilation rate (VE) = 6000 ml/minute
4.
Tidal volume = 600 ml
breathing rate = 10 breath/min
death space volume = 150 ml
Alveolar ventialtion rate = (Tidal volume - death space volume) X breathing rate
Alveolar ventialtion rate = (600 - 150) X 10 = 4500 ml/min
5. The correct answer is alveolar rate is decresed.
Alveolar ventialtion rate = (500-150) X 12 = 350 X 12 = 4200 ml/min
when tidal volume and breath rate changed to 400 ml and 15 breath/min
Alveolar ventialtion rate = (400 X 150) X 15 = 3750
Hence, alveolar rate will be decrease.
6. Vital capacity is the maximum amount of air a person can expirate from the lungs after a maximum inhalation. It is the summation of inspiratory reserve volume, expiratory reserve volume and tidal volume.Hence, it is free from residual volume.
