Anatomy & Physiology 3 Lab, Midterm Quiz Questions

Questions are short answer or identification; some may require calculations

Respiratory Ventilation
1.	Define tidal volume.
2.	Relative to breath-holding after a maximal inspiration of air, what was the effect of hyperventilating 100% oxygen on breath-holding?
3.	Given an average tidal volume of 620 ml and a respiratory rate of 18 breaths per minute, calculate the pulmonary ventilation in l/min.
4.	Typically, who has the greater maximal lung volume, a 55 kg male or a 55 kg female?
5.	What is the residual volume? Go to top

Energy Metabolism
1.	Barometric (atmospheric) pressure is always presented by weather reporters in this country in inches. But in scientific investigations, we need the value in mm Hg. If the meteorologist says the barometric pressure is 29.25 and falling, what is the value in mm Hg?
2.	You collected the expired air into a large balloon or bag. What is that called?
3.	Given the fractional concentration of oxygen in inspired air (FIO2) was 21%, the fractional concentration of oxygen in the expired air (FEO2) was 16.6%, and the volume of gas inspired (VI) was 43 l over 5 min. Assuming no corrections were necessary, what was the VO2 in l/hr?
4.	Using your result from Q3, how many kcal/hr were used, assuming a value of 4.8 kcal/l O2? Go to top
