  1. Circulatory System! By: Mary Currin

  2. Facts about the circulatory system… • the longest system of the body • If one were to lay all the blood vessels in a single human body end to end, they would stretch one fourth the way from earth to the moon a distance of 60,000 miles • The blood and lymphatic system are part of the circulatory system

  3. anatomy • Pulmonary arteries- take blood away from right ventricle to the lungs for oxygen • Pulmonary veins- brings oxygenated blood from the lungs to the left atrium • Aorta- takes blood away from the left ventricle to the rest of the body • Superior and the inferior vena cava- the large veinous blood vessels which bring deoxygenated blood to the right atrium from all the parts of the body

  4. structure

  5. Functions • The heart is the pump that circulates blood to all parts of the body • Arteries, veins, and the capillaries are the structures that take blood from the heart to the cells and return blood from the cells back to the heart • Blood carries oxygen and nutrients to the cells and carries the waste products away • The lymph system returns excess fluid from the tissues to the general circulation and manufactures lymphocytes

  6. Diseases of the heart • Arrhythmia or dysrhythmia- term used to discuss any change or deviation from the normal rate or rhythm of the heart • Bradycardia- term used for slow heart rate (less than 60 beats per minute) • Tachycardia- term used for rapid heart rate (more than 100 beats per minute) • Murmurs- indicates defects in the valves of heart • Mitral valve prolapse- condition where the valve between the left ventricle closes imperfectly

  7. Infectious disorders of the heart Pericarditis- inflammation of the outer membrane covering the heart Myocarditis- inflammation of the heart muscle. Endocarditis- inflammation of the membrane that lines the heart and covers the valves. Rheumatic heart disease- valve becomes inflamed, then the mitral valve is unable to close property, which interferes with blood flow from left atrium to left ventricle. This could be a result of a person that had frequently strep throat in their childhood.

  8. Infectious diseases continued… myocarditis Rheumatic heart disease
