Physiology final- Pulmonary

If the total lung capacity is 6L, the tidal volume is 500ml (0.5L), the inspiratory reserve volume is 3000ml (3L) and the expiratory reserve volume is 1,500ml, what is the vital capacity?

5,000 ml or 5L

What are the differences between lung volumes and lung capacities?

Lung capacities are, for the most part, fixed and are made up of two or more lung volumes. Lung volumes vary depending on the level of activity (except residual).

What is the difference between volume measurements and capacities?

Volume measurements are the amount of air in the lungs that are actually involved in a given activity of the respiratory cycle and capacities refer to how much air the lungs can hold for a given purpose in the respiration cycle

Define tidal volume

Volume of air exchanged in one quiet breath

If you exercise, your breathing will become heavier and deeper leading to: a) a decrease in the tidal volume and a concomittant increase in the inspiratory and expiratory reserve volumes b) an increase in the tidal volume and a concomittant decrease in the inspiratory and expiratory reserve volumes c) an increase in the vital capacity d) a decrease in the vital capacity

b) an increase in the tidal volume and a concomittant decrease in the inspiratory and expiratory reserve volumes

Which of the following respiratory volumes is usually the smallest? a) residual b) tidal

b) tidal

Which of the following is not a component of the upper respiratory tract? a) nasal cavity b) trachea c) larynx d) pharynx

b) trachea

The sum of tidal, inspiratory reserve, and expiratory reserve volumes is called: a) expiratory capacity b) vital capacity c) residual capacity d) inspiratory capacity

b) vital capacity

The vital capacity refers to the amount of air that is available for exchange (inhalation and exhalation) in the lungs during respiration. It is comprised of: a) Inspiratory Reserve Volume +Tidal Volume +Expiratory Reserve Volume+ Residual Volume b) Inspiratory Reserve Volume +Expriatory Reserve Volume c) Inspiratory Reserve Volume +Tidal Volume +Expiratory Reserve Volume e) Expiratory Reserve Volume+Residual Volume

c) Inspiratory Reserve Volume +Tidal Volume +Expiratory Reserve Volume

The typical lung capacity (total lung capacity) is 5 - 6 liters. The typical residual volume is 1 L. Assuming the lung capacity of an individual is 6L and he has a tidal volume of 500 ml and an inspiratory reserve volume of 3L, what is his vital capacity? a) 6L b) 3.5L c) 6.5L d) 5L

d) 5L

The residual volume of the lungs: a) is removed from the lungs only when one exhales deeply b) is a volume that changes depending on the level of activity at a given moment - for example is the person exercising or relaxing? c) is included in the calculation of the vital capacity d) serves the function of preventing the lungs from collapsing

d) serves the function of preventing the lungs from collapsing

The difference between a lung volume and capacity is that: a) a lung volume is the amount of air in the lungs whereas the lung capactiy is the amount of air the lungs can hold b) a lung volume is a combination of two or more lung capacities c) a lung capacity is a combination of two or more lung volumes d) Lung capacities vary depending on the amount of physical activity - whether you are running or seated, for example whereas the lung volumes are constant e) Lung volumes vary depending on the amount of physical activity - whether you are running or seated, for example whereas the lung capacities are constant f) 1, 3, 5 g) 2, 3, 4

f) 1, 3, 5

What is the effect of exercise on the inspiratory reservemvolume? Does it increase, decrease, or stay the same during exercise?

it decreases

What is the effect of exercise on tidal volume? Does it increase, decrease, or stay the same during exercise?

it increases

Define Tidal Volume

volume of air expired or inspired during a single breath

Define Expiratory Reserve Volume

volume of air that can be maximally exhaled at the end of a tidal expiration.

Define Inspiratory Reserve Volume

volume of air that can be maximally inhaled at the end of a tidal inspiration.

Define Residual Volume

volume of gas remaining in the lungs at the end of a maximal expiration

What is the effect of exercise on vital capacity? Does it increase, decrease, or stay the same during exercise?

It stays the same.

Define Pulmonary Capacity

How much air the lungs can hold for a given purpose
