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.
R.Q. for glucose is:
C6H12O6 + 6O2 → 6CO2 + 6H2O
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:
Which of the following statement is correct?
In humans, which among these is not a step in respiration?
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:
Tidal volume is approximately 500ml while residual volume is 1100-1200 ml.
