piratory Systen
RESPIRATION
A car needs energy to run. We fill petrol in the car. The petrol
burns, and gives energy to the car to run. Similarly, the food
reacts with oxygen of the air and energy is released by the
oxidation of food. For this, we need oxygen. The process
of taking in oxygen by the cell, oxidation of food with this
oxygen and the release of energy and carbon dioxide is called
&R R
