The River of Life
Imagine a transport system that delivers oxygen and nutrients to every cell in your body, removes waste products, fights infections, and repairs damage - all while flowing through 100,000 kilometers of vessels. This is your circulatory system, where blood acts as the delivery service and blood vessels form the highway network. Understanding blood and its vessels reveals how your body maintains life at the cellular level.
