1. The Cardiovascular System (The Circulatory system) By: Deki Ryan

2. What are the parts of the Cardiovascular System The parts of the Cardiovascular system are: Heart Veins Arteries Blood Vessels

3. The Heart Process After blood is delivered to the right atrium by the inferior vena cava and superior vena cava it goes through the tricuspid valve to the right ventricle. Then it goes through the pulmonary valve. Then it goes to the pulmonary artery were it goes to the lungs to receive oxygen so it can turn to oxygenated blood. Then it comes back to the heart from the pulmonary vein where it goes to the left atrium. Then it goes through the Mitral valve to the left ventricle. Where then the blood goes through the aortic valve to the aorta where the blood gets pumped out into all part of the body in arteries. When it gets to the end it goes through the capillaries to the veins were it gets pumped back to the heart were the process starts all over again.

4. Veins and Arteries Veins Bring blood that is not oxygenated back to the Heart, that’s why it’s blue. Arteries brings oxygenated blood away from the heart to the other parts of the body, that’s why it’s red.

5. Blood vessels The blood vessels are the part of the circulatory system that transports blood throughout the body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.

6. What are the functions of the cardiovascular system The functions of the circulatory system are: Transport gases, like oxygen from the lungs to cells around the body and carbon dioxide from the cells to the lungs. Transport nutrients like glucose. Transport wastes from cells to organs that play the role of eliminating them. It contains cells that fight infections and defend against foreign bodies. Maintains the pH levels and ionic concentration of fluids in the body. Helps maintain the body temperature, this is especially important in warm blooded animals like humans.

7. Components of the blood The components of the blood are: Red blood cells, white blood cells, Platelets, plasma. Red blood cells are 45% of blood. They give the blood its red color. They transfer the oxygen to the parts of the body. White blood cells are only 1% of blood but they are the ones who fight infection. Plasma is the liquid part of blood. It contains it is 90% water and in the 10% there are Nutrients-eg amino acids, glucose and vitamins Waste products-eg urea Hormones-eg adrenaline and insulin Mineral salts-eg calcium and iron Plasma proteins-eg prothrombin, fibrinogen and albumin Respiratory gases- eg carbon dioxide and oxygen Platelets are a small colorless disk-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting.

8. Diseases Diseases or illnesses you can get are: Heart disease, Atherosclerosis, High blood pressure, Angina, and Stroke

10. Vocab Aorta-the main trunk of the arterial system, conveying blood from the left ventricle of the heart to all of the body except the lungs. Artery- Anatomy. A blood vessel that conveys blood from the heart to any part of the body.A main channel or highway, es pecially of a connected system with many branches. Capillary- Any of the branching blood vessels that form a network between the arterioles and venules. Vein- Any of the tubes forming part of the blood circulation system of the body, carrying mainly oxygen-depleted blood toward the heart. Ventricle- A hollow part or cavity in an organ, in particular. Each of the two main chambers of the heart, left and right. Vena Cava- Either of two large veins that carry blood with low levels of oxygen to the right atrium of the heart. The superior vena cava receives blood from the brain and upper limbs or forelimbs. The inferior vena cava drains blood from the trunk and lower limbs or hindlimbs and is the largest vein in the body. Atrium- An entry chamber. On both sides of the heart, the atrium is the chamber that leads to the ventricle. Valve- A device for controlling the passage of fluid through a pipe or duct, esp. an automatic device allowing movement in one direction only.
