Question

Toppr Admin · Accepted Answer

Breathing is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment- mostly by bringing in oxygen and flushing out carbon dioxide- The breathing consists of repetitive cycles of inhalation and exhalation through airways which lead from nose to the alveoli-The composition of air in the atmosphere and in the alveoli differ- -xA0-Alveolar air contains a greater amount of carbon dioxide and less oxygen than atmospheric air- This is because gas exchange removes oxygen from and adds carbon dioxide to the alveolar air- Both deep and forced breathing cause alveolar air composition to be changed more rapidly than during quiet breathing- As a result of this the partial pressures of oxygen and carbon dioxide change- affecting the diffusion process that moves gases across the membrane- This will cause oxygen to enter and carbon dioxide to leave the blood more quickly- thus there will be high oxygen and very little carbon dioxide in the blood-Thus- the correct answer is option D-

A person sitting at rest experiences a temporary cessation of breathing after forced deep breathing for a few minutes. This is due to
Too much $C O_{2}$ in the blood
Too much $O_{2}$ in the blood
Very little $C O_{2}$ in the blood
Both high $O_{2}$ and very little $C O_{2}$ in the blood
