Now you've made it all the way to the circulatory system. Things are really moving here! Here are some things you should know about the circulatory system:

greatest volume of blood ever donated
  • Arteries are tubes that carry blood away from the heart
  • Veins are tubes that return blood to the heart
  • Capillaries connect arteries and veins. They are tiny tubes that exchange food, oxygen and wastes between blood and body cells.
  • Pulmonary circulation is the movement of blood between the heart and lungs
  • Coronary circulation is the movement of blood from within the heart chambers to the heart tissues themselves
  • Systemic circulation is the movement of blood between the heart and the rest of the body

The circulatory system is pretty important, huh?
