Vedclass · Answer

(D) $1$. The breathing cycle involves the inhalation of $O_2$ and exhalation of $CO_2$ through the expansion and contraction of the thoracic cavity.$2$. If the breathing cycle stops, the intake of $O_2$ ceases, and $CO_2$ accumulates in the body.$3$. Since cells require a continuous supply of $O_2$ for cellular respiration and need to expel $CO_2$ to prevent toxicity, the breathing cycle is essential for maintaining gas exchange.$4$. Failure of this process leads to suffocation and can be fatal.

The breathing cycle is an essential process for the exchange of gases. Justify this statement.
