In breathing movements, the air volume can be estimated by:
Spirometry is the process of recording the changes in the volume and movement of air in and out of the lungs and the instrument used for this purpose is called a spirometer or respirometer.
Respiratory quotient is defined as:
The respiratory quotient (RQ) is the ratio of CO2 produced to O2 consumed while food is being metabolized.
RQ = CO2 eliminated/O2 consumed
The vital capacity of the lungs includes:
Dead space air in man is ______.
Dead space is the volume of air which is inhaled that does not take part in gas exchange because it remains in the conducting airways or it reaches alveoli that are not perfused or poorly perfused.
A person breathes in some volume of air by forced inspiration after having a forced expiration.
This quantity of air taken in is:
Hence, the correct answer is option B: Vital Capacity
Which of the following statement is correct?
In humans, which among these is not a step in respiration?
So, the correct answer is 'The utilisation of CO2 by cells for catabolic reactions'.
The amount of volume of air which can be inspired/expired normally is called:
Tidal volume (TV) measures the amount of air that is inspired and expired during a normal breath.
Residual volume is:
Respiration in mature mammalian erythrocytes are __________
Sometimes aerobic and sometimes anaerobic.
