How does the immune system support cellular respiration?

The immune system supports cellular respiration indirectly by maintaining the overall health and functionality of cells. It protects against infections and diseases that could impair cellular processes, ensuring that cells receive adequate oxygen and nutrients for efficient respiration. Additionally, immune cells themselves require energy for their functions, relying on cellular respiration to produce the ATP needed for their activities in defending the body. Thus, a well-functioning immune system is crucial for sustaining the metabolic processes of all cells.
