The human body contains over 37 trillion cells, and every single one of them is constantly working together to keep us alive. The heart beats around 100,000 times per day, pumping blood through the body's vast network of veins, arteries, and capillaries. It's a truly remarkable machine, but it can't function without a steady supply of oxygen and nutrients. That's where the lungs come in – they take in oxygen from the air we breathe and release carbon dioxide as waste.
