Answer 1

The respiratory system supplies energy to the body by taking in oxygen from the air we breathe. This oxygen is then carried to all the cells in the body by the bloodstream. The cells use this oxygen to help convert the food we eat into energy through a process called cellular respiration. This energy is essential for all the body's activities, like moving, thinking, and even just staying alive.
