This document describes the structure and function of the cardiovascular system. It details the major organs including the heart, arteries, veins and capillaries. The heart is described as having four chambers - two atria that receive blood and two ventricles that pump blood out. Blood moves through the heart chambers via valves between the atria and ventricles. Arteries carry oxygenated blood away from the heart while veins return deoxygenated blood back to it. Capillaries allow for the exchange of oxygen and nutrients with body tissues. In conclusion, the right side of the heart contains deoxygenated blood and the left side contains oxygenated blood, and the heart chambers work together to pump this blood throughout the body

- 3. The Cardiovascular System Structure & Function
- 4. Organs of the Cardiovascular System Heart Blood vessels Arteries Arterioles Capillaries Veins Venules
- 5. The Heart Muscular organ the size of a fist Four chambers – L/R Ventricles L/R Atria Endocardium- lines the heart chambers Myocardium- muscle layer Pericardium- membranous outer covering
- 6. Atria Right Atrium (RA)- right upper chamber-receives blood from body- deoxygenated blood Left atrium (LA)- left upper heart.- receives oxygenated blood from lungs and sends it to the left ventricle
- 7. Ventricles Right ventricle- (RV)- right lower chamber-receives blood from right atrium and sends it to the lungs through pulmonary artery Left Ventricle (LV)- lower left chamber-receives blood from left atrium and sends it through the aorta to the body.
- 8. Aorta: The main trunk of the systemic arteries, carrying blood from the left side of the heart to the arteries of all limbs and organs. Pulmonary Artery carries blood to lungs Right Atrium Right Ventricle Left Atrium Left Ventricle Aorta pulmonary artery
- 9. Pulmonary valve controls blood movement from right ventricle into pulmonary artery The aortic valve controls blood flow from the left ventricle to the aorta Pulmonary valve Right Atrium Right Ventricle Left Atrium Left Ventricle Tricuspid Valve Mitral Valve Aortic valve
- 10. Tricuspid valve controls blood flow between the right atrium and ventricle Mitral valve controls blood movement between the left atrium and ventricle Right Atrium Right Ventricle Left Atrium Left Ventricle Tricuspid Valve Mitral Valve
- 11. Arteries Arteries- tubes that carry blood away from the heart. Muscular elastic walls Form arterioles which form capillaries Carry blood and oxygen to the body cells
- 12. Veins Veins- tubes that carry blood toward the heart Thinner muscular walls Carry blood back to heart Cuplike valves to help move blood
- 13. Capillaries Capillaries- tubes that connect arteries and veins Walls only one cell thick Site for exchange of nutrients and oxygen from blood cells and carbon dioxide and wastes to the blood
- 15. CONCLUSION The chambers on the right side contain impure blood & those on the left side contain pure blood. The right & left atria get filled with blood they contract together & the blood goes to the ventricles. The ventricular contraction blood from the left ventricle enters the aorta & the blood from the right ventricle enters the pulmonary artery
