Description
In Circulatory & Respiratory Systems, 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. A visit to a hospital blood laboratory is included, as well as an interview with a doctor and a fun, hands-on activity in which students can test their lung capacity.
