Parts of Our System Arteries- tubes that carry blood away from the heart Veins- tubes that return blood to the heart Capillaries- connect arteries and veins. They are tiny tubes that exchange food, oxygen and wastes between blood and body cells. Pulmonary circulation- is the movement of blood between the heart and lungs Coronary circulation- is the movement of blood from within the heart chambers to the heart tissues themselves Systemic circulation- is the movement of blood between the heart and the rest of the body

Parts of Our System Continued. Atrium- either section of the upper area of the heart which is divided into left and right chambers. Capillary- a microscope, linking blood vessel diastole-the relaxation stage of the heart muscle in it’s normal cyclical rhythm. Septum- a wall separating two cavities,especially the left and right sides of the heart. Systole- the normal, rhythmic contraction of heart muscles. Vena Cava- either of the large veins, superior or inferior, by which blood is returned to the right atrium of the heart. Ventricle- either of the two lower, pumping chambers of the heart

The Heart On average, your heart beats 70 times a minute. When the heart pumps, the right side and left side work together. The middle is just a wall. It has 4 chambers. The upper chamber receives blood entering the heart and pumps it to the ventricles. The right side receives blood carrying carbon dioxide to the body and delivers it to the right ventricle (either of the two lower pumping chambers of the heart). The left receives the oxygen-rich blood from the lungs and delivers it to the left ventricles.

Heart Attack A heart attack is a clogged artery or a blockage caused by a clot. Treatment: Don’t eat a lot of fatty foods. Drink Orange Juice. Exercise regularly. (CPR) or (AED) cardiac drugs breathing tubes and/or surgery thrombolysis is a procedure that involves an injection of a clot-dissolving agent such as streptokinase, urokinase, or tissue plasminogen activator

Heart Attack Symptoms: Pressure in the chest area, the left arm, and/or pressure in the area around the heart.

Atherosclerosis When the fatty material, like cholesterol, accumulates on the artery wall forming a plaque that obstructs blood flow. Treatment- medicine, surgery, high-fiber, diet low in fat, and exercise

Atherosclerosis Con. No early symptoms Symptoms of coronary artery disease –Angina –Heart attack –Coronary thrombosis Symptoms of brain artery disease –Stroke –Transient ischemic attack Symptoms of leg artery disease –Leg blood clot –Leg pain –Leg cramps –Intermittent claudication Other symptoms –Erectile dysfunction
