CARDIOVASCULAR SYSTEM CIRCULATORY SYSTEM CARDIOVASCULAR SYSTEM

Heart

Heart (continued) Septum Heart chambers Valves Tricuspid Pulmonary Mitral Aortic

Heart (continued) Cardiac cycle *diastole - period of rest *systole – period of ventricular contraction Conductive pathways Arrhythmias *abnormal heart rhythms

Blood Vessels Blood carried throughout body in blood vessels Arteries - carry blood away from the body Capillaries - connect arteries and veins (very thin and fragile) Veins – carry blood back to the heart (superior and inferior vena cava)

Blood

Diseases and Abnormal Conditions Anemia Aneurysm Arteriosclerosis Atherosclerosis Congestive heart failure (CHF) Embolus

Diseases and Abnormal Conditions (continued) Hemophilia Hypertension Leukemia Myocardial infarction – heart attack Phlebitis Varicose veins
