HUTCHINSON SCHOOL–The circulatory system includes the heart, blood vessels, and the blood.The heart is an important muscle in your body.  Your heart doesn’t get tired, but if it did, and stopped beating, you would die. The movement of blood through your body is called circulation.

Your heart has two chambers.  The upper chambers are the right atrium and the left atrium, and the two lower chambers are the right ventricle and the left ventricle.  Your heart pumps blood.  There are three types of blood cells:  White blood cells, red blood cells, and platelets.

Esme Navarro says, ”The circulatory system is very interesting to learn.”

Ms. Buzin, who teaches science in Class 5R, says,  ”I love teaching and learning about the circulatory system….it is challenging and fun!”

Your heart is the size of your fist.  The color of your heart is red.  The three types of blood vessels are arteries, veins, and capillaries.  The right ventricle pumps blood through the artery and into the lungs.  The blood is then carried by the vein into the left atrium, and then the  left ventricle pumps blood through the aorta and into the rest of the body.  The process keeps repeating, so the blood is always circulating through the body.

Here are more facts.  Red blood cells carry oxygen from the lungs into the body cells. Oxygen-rich blood is bright red.  White blood cells fight disease-causing germs.  They also remove dead blood cells.  Platelets are parts of cells that stick together to help the blood clot or thicken.

 The circulatory system is fascinating!
