The infection caused his lungs to be filled with fluid. As a result, his breathing rate was affected as shown below https://padlet.com/mshuimathsci/2026pyps6IScience/wish/4019889486


a) Describe the change in Mr Tan's breathing rate after getting the bacterial infection and explain why. 


3. Answer:

Mr Tan breathed faster after a bacterial infection. When Mr Tan's lungs are filled with fluid, there is lesser space for the air in the lungs can hold, so Mr Tan breathes faster to take in enough air for respiration to release energy and carbon dioxide.


b) The doctor also noticed that Mr Tan heart rate had increased due to the lung infection. explain how the increase in his heart rate helps Mr Tan to survive.


Answer: 

Heart needs to pump faster to transport blood-rich in digested food to all parts to supply enough for his body.
