The human body is a complex and highly adaptable machine. It can perform a wide range of functions without us even thinking about them. Our hearts beat at a steady pace, pumping blood throughout our bodies. Our lungs take in oxygen and expel carbon dioxide through the process of breathing. We digest food in our stomachs, breaking it down into nutrients that give us energy to keep going. Our brains process information, allowing us to learn and remember things. And yet, despite all these incredible abilities, humans are still vulnerable to illness and injury.
