During congestive heart disease there is a reduced efficiency of gas exchange
In emphysema, the gas exchange reduces. The surface area available for gas exchange is reduced.
A fall in inspired oxygen pressure at higher altitude reduces the driving pressure for gas exchange in the lungs
Fick's Law of diffusion (p. 137 Silverthorm) governs the rate at which oxygen moves from the...
Name 13. During gas exchange in the lungs, several factors affect the rate of gas diffusion across alveolar (the alveoli are tiny air sacs in the lungs) and tissue membranes. One of the factors is the difference in partial pressures of the gases across the membranes. The gases will diffuse from an area of high partial pressure to an area of low partial pressure, Look at the illustration below and note which blood vessels carry blood away from the lungs...

How are Oxygen and CO2 transported in blood? 4. What is physiological dead space? Know the formula for calculation alveolar ventilation rate. 5. Describe location of chemoreceptors. Which stimuli affect their activity? 6. Describe all lung receptors. What are the effects of sympathetic and parasympathetic nervous system on respiration? OBSTRUCTIVE & RESTRICTIVE DISEASES...
Question 37 Which of the following increases oxygen unloading? decreased BPG e decreased pCO2 in the plasma All of these answers are correct. increased blood pH increased body temperature Question 38 What is a classic scenario, as described in class, where oxygen unloading would be increased? while eating food during exercise during tidal volume breathing while drinking water divas → XCIO D Question 39 Which of the following is FALSE regarding breathing? It requires skeletal muscles for normal, quiet exhalation....
