Circulatory System
What is the job of the Circulatory System?
The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all your body cells. Parts of the Circulatory System
The circulatory System is divided into three major parts: 1. The Heart 2. The Blood 3. The Blood Vessels
The Heart
The Heart is an amazing organ. The heart beats about 3 BILLION times during an average lifetime. It is a muscle about the size of your fist. The heart is located in the center of your chest slightly to the left. It's job is to pump your blood and keep the blood moving throughout your body.
The Blood
The blood is an amazing substance that is constantly flowing through our bodies. * Your blood is pumped by your heart. * Your blood travels through thousands of miles of blood vessels right within your own body. * Your blood carries nutrients, water, oxygen and waste products to and from your body cells. * A young person has about a gallon of blood. An adult has about 5 quarts. * Your blood is not just a red liquid but rather is made up of liquids, solids and small amounts of oxygen and carbon dioxide.
Blood Cells
Red Blood Cells
Red Blood Cells are responsible for carrying oxygen and carbon dioxide. Red Blood Cells pick up oxygen in the lungs and transport it to all the body cells. After delivering the oxygen to the cells it gathers up the carbon dioxide (a waste gas produced as our cells are working) and transports carbon dioxide back to the lungs where it is removed from the body when we exhale(breath out). There are about 5,000,000 Red Blood Cells in ONE drop of blood.
White Blood Cells
White Blood Cells help the body fight off germs. White Blood Cells attack and destroy germs when they enter the body.
