What happens to the respiratory process in a man going up a hill? | NCERT solution | Class 11 Biology | Unit-17 Breathing and exchange of gases



Q.9:- What happens to the respiratory process in a man going up a hill?

 

Answer:



A man going uphill has to exert more effort to climb. This increases the consumption of oxygen. As a result, the partial pressure of oxygen in haemoglobin decreases which creates more demand for oxygen. This is compensated by an increased breathing rate.
