The human body is a complex and intricate machine that functions optimally when all systems are working together in harmony. The heart pumps blood throughout the circulatory system, supplying oxygen and nutrients to every cell, while the lungs breathe in oxygen and exhale carbon dioxide through the respiratory system. The digestive system breaks down food into nutrients that are absorbed by the small intestine, where they are then transported to cells throughout the body via the bloodstream.
