Lesson Three: Circulatory System (Part One)

Circulatory System
(Part One)

Science Fast-Fact
  • Red blood cells carry oxygen from the lungs to all the cells of the body.
  • White blood cells are like soldiers protecting the body.
  • ARTERIES are vessels that carry blood away from the heart.
  • VEINS are vessels that carry blood back to the heart.
  • Blood CIRCULATES--circles--all around your body in about one or two minutes.
  • Inside the heart there are four hollow chambers. Each chamber is a little pump. The pumping pushes blood all around your body.
