Question 1

Which of the following respiratory volumes and capacities has the lowest volume?

Accepted Answer

Tidal volume (TV) is the amount of air inhaled or exhaled during normal breathing, which is typically lower in volume compared to the expiratory reserve volume (ERV), residual volume (RV), functional residual capacity (FRC), and inspiratory reserve volume (IRV).

Question 2

The expiatory reserve volume (ERV)is a much larger volume than the inspiratory reserve volume (IRV).

Accepted Answer

The inspiratory reserve volume (IRV) is typically larger than the expiratory reserve volume (ERV). IRV is the additional air that can be inhaled after a normal inhalation, while ERV is the additional air that can be exhaled after a normal exhalation.

Question 3

If you exhaled normally into the environment, and then blew all of the air that you could into a balloon, the volume of air in the balloon would represent the

Accepted Answer

The expiratory reserve volume (ERV) is the additional amount of air that can be exhaled after a normal exhalation, which is what you would blow into the balloon after exhaling normally.

Question 4

The volume of air remaining in the lungs after a tidal expiration is called the

Accepted Answer

The functional residual capacity (FRC) is the volume of air remaining in the lungs after a normal, tidal expiration. It includes the residual volume (RV) and the expiratory reserve volume (ERV).

Question 5

In the experimental analysis, the difference in amplitude between the peak of a normal inspiration and the peak of the maximal inspiration would represent the

Accepted Answer

The inspiratory reserve volume (IRV) is the amount of air that can be forcibly inhaled after a normal tidal volume inspiration. The difference in amplitude between the peak of a normal inspiration and the peak of the maximal inspiration represents the amount of air that can be inhaled in addition to the normal tidal volume, which is the IRV. Therefore, the correct answer is A.

Question 6

Inspiratory capacity (IC)cannot be measured with a spirometer.

Accepted Answer

Inspiratory capacity (IC) can be measured with a spirometer. IC is the maximum amount of air a person can inhale after a normal exhalation, and it can be calculated by subtracting the end-tidal volume (the volume of air left in the lungs after a normal exhalation) from the total lung capacity measured by the spirometer.

Question 7

Total lung capacity (TLC)cannot be measured with a spirometer.

Accepted Answer

TLC cannot be directly measured with a spirometer because it includes the residual volume, which is the amount of air remaining in the lungs after a maximal exhalation, and cannot be measured by spirometry.

Question 8

Obstructive lung diseases, such as chronic bronchitis, often cause an elevation in the functional residual capacity (FRC)and the residual volume (RV).

Accepted Answer

Obstructive lung diseases can cause air trapping, leading to increased FRC and RV due to difficulty exhaling all the air from the lungs. This is a characteristic feature of obstructive lung diseases.

Question 9

A respiratory capacity is the sum of two or more volumes.

Accepted Answer

A respiratory capacity is the sum of two or more volumes, such as the inspiratory capacity, functional residual capacity, and vital capacity.

Question 10

Which of the following is not true of the vital capacity (VC)?

Accepted Answer

Vital capacity (VC) is calculated by adding the inspiratory reserve volume, expiratory reserve volume, and tidal volume, not just the inspiratory and expiratory reserve volumes.

Question 11

Expiratory capacity (EC)is the sum of ________ and ________.

Accepted Answer

Expiratory capacity (EC) is the maximum amount of air that can be exhaled from the lungs after a quiet expiration. It is calculated by adding tidal volume (TV) and expiratory reserve volume (ERV). Therefore, the best choice is B, which includes TV and ERV.

Question 12

Which of the following is not a correct formula for calculating total lung capacity (TLC)?

Accepted Answer

IC + EC is not a correct formula for TLC because it does not include residual volume (RV). TLC is the sum of all lung volumes, including RV, therefore the correct formulae for TLC should include RV, which is present in options A, B, and C.

Question 13

Which of the following is not a use for oxygen in the body?

Accepted Answer

Anaerobic breakdown of glucose occurs without the use of oxygen. While oxygen is necessary for many cellular processes, anaerobic breakdown of glucose occurs in the absence of oxygen and therefore does not require oxygen.
