Understanding the Human Body's Energy Sources and Processes
Energy is the fundamental force that powers all living organisms, allowing them to perform essential functions necessary for survival and growth. In the case of humans, understanding how the body obtains and utilizes energy is crucial for maintaining overall health and well-being.
