The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them. ~William Lawrence Bragg getting there..

So tonight I decided that I should start answering the questions that were given to me. I worked on it for about an hour or so. This is what I ended up with: What parts make up the system? The circulatory system is made up of vessels and muscles that help control the flow of the blood around the body. The system is divided into 3 major parts. Those parts are the heart, the blood and the blood vessels. There are 3 types of blood vessels and they are arteries, capillaries and veins. The arteries are used to carry rich-oxygen blood away from the heart and then provide it to tissues, and then it returns the blood cells back to the heart through the veins for reoxygenation. With all these things happening within the body, all together it makes up the circulatory system. Why do we need it? The circulatory system helps us, as it provides our body cells with all the oxygen and nutrients it needs. If our body cells did not have enough oxygen and nutrients, we humans would not be able to survive. Waste like carbon dioxide is also removed by the circulatory system and it is replaced with fresh oxygen that we have breathed in through our lungs. The human circulatory is a system of vessels that distribute blood throughout our entire body. In the middle of the circulatory system is our heart which circulates blood throughout the veins and arteries. So without this system we would have no blood in our bodies, we would not get all the nutrients and oxygen we need to survive, we would’ve been living with no heart (which is impossible and you would die straight away) and we would also have a lot of waste in our bodies that could possibly cause death. So yeah. I just have to check with my group if the answers are okay and if I have to change anything around or add more information. So I'll do more research later on to see if i can find anymore facts. But thats all for now (: laters.
