2. Words you may need to know. Arties- Blood vessel that carries blood away from the heart and has thick elastic walls made of connective tissue and smooth muscle tissue. Aorta- Branches into smaller arteries, which then branch into even smaller vessels that travel all over the body. Capillaries- Are found in body tissue Hypertension- Elevation of the blood pressure; the diastolic pressure Atriums-heart beat Ventricles- 2 lower chambers Artery- blood vessel Vein- carries blood Capillary- connects artery and vein

3. More words you may need to know Plasma- liquid part of blood Hemoglobin- chemical in red blood cells Platelet- body form in life cycle Pulmonary circulation- flow of blood Systemic Circulation- biggest part of the system Coronary Circulation- forms a tissue in heart. Heart-The chambered muscular organ in vertebrates that pumps blood received from the veins into the arteries, there by maintaining the flow of blood through the entire circulatory system.

4. Introduction Do you know where is your circulatory system? How you use is? What is it used for? Why do you even have it? In this slide show you will find out all the answers that you would need to know or find out. So lets go in side your body and discover where your circulatory system is, what is it used for and why you have it, all of the questions you have will be answered.

5. The system and its functions The circulatory system is the body’s transport system. It’s mad up of a lot of organs. The Heart pumps the blood and the arties and veins transport it. Oxygen rich blood leaves the left side of the heart and enters the biggest artery called the aorta. The aorta branches into smaller arteries which then branch into smaller vessels that transport all over the body. When blood enters the smallest blood vessels named capillaries and are found in body tissue it gives nutrients and oxygen to the cells and takes in carbon dioxide water and waste. The blood that no longer contains oxygen and nutrients then goes back to the heart through veins. Veins carry waste products away from cells and bring blood back to the heart which pumps it to the lungs to pick up oxygen and throw away bad carbon dioxide The circulatory system is the body’s transport system.

6. The parts of the system and there jobs  The circulatory system is composed of vessels and muscles that control the flow of blood around the body. This process of blood flowing around the body is called circulation. The main components of the circulatory system are the heart, arteries, capillaries and the veins.

7. Diseases and Disorders Diseases and Disorders are important to this system because it can be damaged. A common disease of the system is arteriosclerosis. Blood clots develop in affected vessels. These clots can give heart attacks or strokes. Hypertension makes the heart work harder and can lead to heart attacks, strokes or kidney failure. Another common disease is Cardiovascular. If you get cardiovascular your heart will be affected.

8. Skander’s Paraphrase If We get a diseases or disorder in our system we can be very damaged or ill. We can get hypertension and get heart attacks or strokes.

9. The reason’s this system is important to our body  1.) The circulatory system is important because it pumps blood throughout the body.  2.) The human circulatory system has three main parts. The heart, the blood vessels, & the blood.  3.) It’s important because the heart is what’s keeping us alive. Its pumping blood through out blood vessels into all other organs

10. Kamilla’s Paraphrase My paraphrase is the circulatory system is almost the important system because, if the heart stops or a vein is broken then the whole body will suffer severe damage.
