THE CIRCULATORY SYSTEM By Bianca and Charlee What is the job of the circulatory system? • The circulatory systems job is to transport materials such as nutrients, oxygen, water and billions of blood cells. It also takes away carbon dioxide that your body cells produce. • The circulatory that holds the heart pumps a fair amount around your body. BLOOD!!!!!!! • Red blood cells carry things like carbon dioxide and oxygen. Red Blood cells are very important on blood duty one drop of blood carries in it millions of blood cells. • When a disqusting germ or horrible infection enters the body the white blood cells go over to see is what is happining. White blood cells keep their eyes out for diseases. Blood cells!!!! • There are two types of blood cells in your body one is called white blood cells the other is called red blood cells. Red blood cells are the ones that are formed from bone marrow and are important for the protein Haemoglobin, which carries oxygen White blood cells are made up of platelets carry out the function of warding off infections and blood clotting. Blood cells is the medium the body requires to fill with vitamins and "good bits" to then carry to all parts of your body, like oxygen, nutrients and defence mechanisms to help the body fight off bacteria and diseases. The Heart!!!!!!!! • • • The left side of your heart sends that oxygen-rich blood out to the body. The body takes the oxygen out of the blood and uses it in your body's cells. When the cells use the oxygen, they make carbon dioxide and other stuff that gets carried away by the blood. It's like the blood delivers lunch to the cells and then has to pick up the trash! The white blood cells have a rather short life cycle, living from a few days to a few weeks. A drop of blood can contain anywhere from 7,000 to 25,000 white blood cells at a time. If an invading infection fights back and persists, that number will significantly increase. A consistently high number of white blood cells is a symptom of Leukemia, a cancer of the blood. A Leukemia patient may have as many as 50,000 white blood cells in a single drop of blood. Important organs in your body!!! • The heart is one of the most important organs in your body because it has the job of pumping blood all around the body. the heart is protected by your rib cage. Your heart is placed slightly to the left side of your body. Your heart weight is around about half a kilo the heart is a little lighter in the female by about a few grams. your heart is about the size of your fist. The heart parts • The circulatory is made up of three main components the heart , the blood vessels and the blood The heart is the pump, the vessels are the tubes that carry the blood around the body, and the blood is the circulating fluid. The main job for the circulatory system is to keep us alive and to pump the blood around our body. The circulatory system carries food or oxygen to all the different blood cells, in response the circulatory system takes away all the things that are bad for us such as carbon dioxide and other things like bacteria The Lungs!!!!!!!!
