The total volume of air in Jeffrey’s lungs is 5800 mL. If his inspiratory capacity is 3200 and his residual volume is 1000, what is his ERV and FRC?

TLC = 4200, VC = 3200, IC = 2000, What is the FRC and RV?

VC = 3200, IC = 2200, ERV= 1000, RV = 1000, what is TLC?

The total volume of air Sally can inhale is 3400 mL after a quiet exhalation. When Sally is sitting still she breaths 400 mL and there’s 2200 mL of air leftover in her lungs. Calculate or figure out the following values: TV, TLC, IC, FRC, IRV

When at rest, Jeremy inspires and expires 600 mL. While his lungs can fit 7000mL of air, only 5500 can move in and out, if he really really tries. Normally, there’s 3400 mL of air left in his lungs after a quiet exhalation. Calculate or figure out ERV, TV, TLC, IC, FRC, IRV, RV

(1) When engaged in involuntary breathing, which of the following volumes enter and/or exit the lungs? ERV, IRV, TV, VC. Which ones are always voluntary?

Expert Solution

1) Given,

TLC = 4200

VC = 3200

IC = 2000

VC = IRV + TV + ERV = IC + ERV = 3200

3200 = 2000 + ERV

ERV = 3200 - 2000 = 1200 ml

TLC - VC = RV

RV = 4200 - 3200 = 1000

FRC = RV + ERV

FRC = 1000 + 1200 = 2200 ml

2) The total volume of air Sally can inhale after normal quiet exhalation is 3400ml, that means IC = 3400ml

When she is sitting still, that is when undergoing normal inspiration or expiration, the volume of air is 400 ml, that means TV = 400ml

IRV = IC - TV

IRV = 3400 - 400

= 3000 ml

The amount of air left over in her lungs is 2200 ml, that means FRC = 2200 ml

TLC = FRC + IC = 2200 + 3400 = 5600 ml

3) At rest Jeremy inspires and expires 600 ml, men's TV = 600 ml

His lungs can fit 7000 ml, hence TLC = 7000 ml

Only 5500 can move in and out, means VC = 5500 ml

The volume of air normally left in his lungs after normal expiration is 3400 ml, means FRC = 3400 ml

RV = TLC - VC = 7000 - 5500 = 1500 ml

ERV = FRC - RV = 3400 - 1500 = 1900 ml

IRV = VC - (ERV + TV)

= 5500 - ( 1900 + 600)

= 5500 - 2500

= 3000 ml

IC = IRV + TV = 3000 + 600 = 3600 ml

4) TV - can be both normal air which is either breathed in or out

IRV - which is the amount of additional air breathed in

ERV - which is the amount of additional air breathed out

VC - maximum amount of air breathed in

A volume of 2.0 L of air at 37°C is expelled from the lungs into cold surroundings at 1.3°C. What volume (in L) does the expelled air occupy at this temperature? The pressure and the number of gas particles do not change? The pressure inside a 1.0 L balloon at 25°C was 750 mm Hg. What is the pressure (in mmHg) inside the balloon when it is cooled to −58°C and expands to 3.2 L in volume?

At the surface, the average total lung capacity of human lungs is about 6 liters of air (~0.21 ft3). Free divers typically fill their lungs with air and hold their breath while they dive. Assuming that Boyle’s Law accurately reflects changes in the air volume in a free divers’ lungs, calculate the change in volume that would occur in a free diver’s lungs at the following depths below the surface of the ocean: 10m, 20m, 35m, 45m. Finally, the world...
