the most common site for obstruction Which of the following

Which of the following is not a basic physiological process of respiration? Pulmonary gas exchange Glycolytic catabolism Pulmonary ventilation Gas transport Tissue gas exchange Fill in the blanks: According to Boyle\'s law, as the volume of a container increases, the pressure ____. Conversely, as the volume of a container decreases, the pressure _____. Air moves into the lungs when intrapulmonary pressure is less than atmospheric pressure. intrapulmonary pressure is more than atmospheric pressure. blood pressure is more than intrapulmonary pressure. blood pressure is less than intrapulmonary pressure. Passive expiration is achieved primarily by the contraction of the diaphragm and external intercostals. decrease in intrapulmonary pressure. increase in atmospheric pressure. elastic recoil of the lungs. Matching: Match the following pulmonary volumes and capacities with their correct definition or description. Total lung capacity Residual volume Functional residual capacity Vital capacity Inspiratory reserve volume Tidal volume Inspiratory capacity Expiratory reserve volume Volume of air in the lungs after a tidal expiration Volume of air forcibly expired after a tidal expiration Volume of air forcibly inspired after a tidal inspiration Maximum amount of exchangeable and nonexchangeable air in the lungs Maximum amount of air that can be inhaled with a forced inspiration Volume of air remaining in the lungs after forceful expiration Maximum amount of exchangeable air that can be ventilated with forced inspiration and expiration Volume of air exchanged with normal, quiet breathing

Solution

1)Answer is option C.

Pulmonary gas exchange is a process of exchanging gases between lung and tissues,so it is not the correct option.So option a is not correct.

Glycolytic catabolism is the biochemical respiration.

So,option b is not correct.

Gas transport is also a part of lung and Haemoglobin and tissue and last option is tissue gas exchange so it is also not correct.

So,option d and e are wrong.

Pulmonary ventilation is the proces of physical respiration.

Hence,option C is correct.

2)Answer will be:

Decrease,Increase.

According to Boyle\'s law pressure is inversely proportional to volume so volume will increase when pressure decreases and volume will decrease when pressure increases.

3)Answer will be option a.

When intrapulmonary pressure is higher than atmospheric pressure air cannot move into the lung.

So,option b is not correct.

Blood pressure has no relation with gas exchange in lungs.

So,option c,d is not correct.

When intrapulmonary pressure is lower than atmosphere then only air can enter into the lungs.

Hence,option a is correct.

4)Answer is option d.

In case of passive expiration contraction of the diaphragm does not occur

So,option a is not correct.

Decrease in intrapulmonary pressure anbincrease in atmospheric pressure does not play a significant role on passive expiration.

So,option b and c is not correct.

Elastic recoil of the lungs is the main factor thats why passive expiration occurs.

Hence,option d is the correct option.
