FAQs on NCERT Solutions for Class 7 Science Hindi Chapter 10 Respiration In Organisms
1. Why does an athlete breathe faster and deeper than usual after finishing the race?
The body movements that are made when an athlete exercises or runs increase the body’s requirement for oxygen. This is because the organs need more oxygen to produce the energy needed to perform the tasks or exercises. And similarly, after the athlete has finished running, more carbon dioxide is required for expiration. This leads to a higher rate of breathing and faster and deeper breathing than usual by the athlete after finishing the race.
2. Why do we often sneeze when we inhale a lot of dust-laden air?
Our nostrils contain hair that stops the dust particles in the air from entering our respiration system any further. When the air we inhale contains dust particles, these particles are trapped in the nostril hair. But when these particles of dust pass through the hair present in our nostrils and reach the nasal cavity, the mucus lining present there gets irritated by these particles. As a reaction from our body, we sneeze. To know more students can download the free PDF of NCERT Solutions of Class 7 Science.
