Cells at Work!

Inside the human body, an estimated 37.2 trillion cells stay on the job around the clock, keeping everything running smoothly. Newly assigned Red Blood Cell AE3803—bright, eager, and a bit scatterbrained—sets out to master her crucial role of delivering oxygen. Meanwhile, White Blood Cell U-1146 tirelessly patrols the body, confronting invading bacteria before they can settle in.

From platelets lining up to tackle a fresh construction job to the chaos of wounds, allergies, wrong turns on the way to the lungs, and squabbles among similar cell types, day-to-day life is anything but calm. Through constant teamwork and close calls, these hardworking cells do their part to protect the body’s health.
