Kids will discover how these two vital systems work together to help keep us alive through a process called cellular respiration. A close-up look at the components of our blood - plasma, red blood cells, white blood cells, and platelets - reveals just how critical blood is to our survival. Pumped by the heart through a vast network of vessels, our blood is the ultimate pick-up and delivery system, providing vital nutrients, carrying away harmful waste, and fighting against disease and infection.
