FAQ: Which Term Refers To The Total Amount Of Air That Can Be Exhaled After A Maximal Inspiration?

The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. It is the sum of the expiratory reserve volume, tidal volume, and inspiratory reserve volume.

What is defined as the maximum volume of air that can exhaled after a maximal inspiration?

Vital Capacity (VC): The maximum volume of air that can be exhaled after a maximal inspiration. ( VC=IRV+Vt+ERV)

What is the term for the volume of air inhaled and exhaled during a cycle of respiration?

Expiration. — volume is the volume of air inhaled or exhaled during a respiratory cycle.

What is the total amount of air that can be expired after fully inhaling?

The vital capacity (VC), about 4,800 mL, is the total amount of air that can be expired after fully inhaling (VC = TV + IRV + ERV = approximately 80 percent TLC). The value varies according to age and body size.

What is the air that remains after maximal expiration?

Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started.

What is the maximum amount of air taken in during the period of vigorous activity?

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

What term refers to the volume of air inhaled or exhaled with each breath without extra effort applied?

Tidal volume is the volume of air inhaled in a single, normal breath. Inspiratory capacity is the amount of air taken in during a deep breath, and residual volume is the amount of air left in the lungs after forceful respiration.

What is the total amount of exchangeable air?

(The total volume of exchangeable air (vital capacity) for a normal male is the amount of air that can be drawn into the lungs after a forced exhalation and, in this case, is 4800 milliliters.)

Which term refers to the exchange of gases O2 and CO2 that occurs in the capillary networks between the blood and the body’s cells?

The exchange of gases (O2 and CO2) that occurs in the capillary networks between the blood and the body’s cells is called: systemic gas exchange.

What is TV and Irv?

The amount of air that moves in and out of the lungs during inspiration and expiration with quiet breathing is called the tidal volume (TV). The air inspired with maximal inspiratory effort in excess of the tidal volume is the inspiratory reserve volume (IRV).

Which of the following is the maximum amount of air that can be exhaled from the maximum inspiratory level?

Some examples of spirometry measurements are: Forced vital capacity: the maximum amount of air you can forcibly exhale from your lungs after fully inhaling. It is about 80 percent of total capacity, or 4.8 liters, because some air remains in your lungs after you exhale.

What term is referred to the volume of gas expired in one minute?

Minute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person’s lungs per minute.

What term is used to describe the air which remains in the lungs after forced exhalation?

Residual volume is the amount of air that is left in the lungs after expelling the expiratory reserve volume. Respiratory capacity is the combination of two or more volumes.
