The Parts of the Circulatory System

    The circulatory system has a lot of parts and organs. I'm going to tell you some of them. 

     One of them and definately the most important part is the heart. There are also the veins and arteries which are kind of like two long tubes that go through the system. There is also the blood vessels which pumps oxygen out of the heart. There are two platelets the white platelets and the red platelets, the white platelets only come about once every one thousand red platelets. If you have a lot of platelets and your blood type is "o" than you can give them to people who need them. The plasma which is the liquid part of blood carries all the blood cells, it is made in the liver.

            I hope you liked learning about the parts of the circulatory system. I enjoyed teaching you about the parts.
