- lower chambers: ventricles
- upper " : atria
- pulmonary circlation: the flow of the blood from the heart to the lungs and back to the heart
- systemic circulation: moves blood to all body tissue except the lungs
- plasma: transports dissolved nutrients, wastes products, and mineral salts as well as hormones, enzymes and vitamins
- red blood cells: carry oxygen from the lungs to all body cells
- hemoglobin: the oxygen carrying substance in the red blood cells
- white blood cells: deysroy invading pathogens
- platelets: the smallest parts of the blood- they initiate a chain of reactions that results in the clotting of the blood
- blood types: Type A, B, AB, O
- universal donor: people with type O blood can give blood to anyone

- systolic pressure: the point when the blood surges throught the arteries with such a force that the arteries bulge
- sphygmomanometer: an instrument used to messure blood pressure
- arteries: largest blood vessels, carry blood away from the heart
- capillaries: smallest blood vessels, nutrients and oxygen from blood pass to body cells through capillary walls, waste products from the cells move into the blood through capillary walls

- hemophilia: an inherited disease in which a clotting factor is absent or abnormal
- anemia: a condition caused by a dificiency of re blood cells or by a low concentration of hemoglobin in the red cells
- 3 ways to keep the cardiovascular system healthy
-don't smoke
-regular excercise
-regular medical check-ups

Health Vocab lesson # 19
- hypertension:when a persons blood pressure stays above his or her normal pressure. (high blood pressure)
- complications(of hypertension): since there is no cure, people can have a stroke, heart attack, heart failure, or kidney failure

- 3 ways to control hypertension:
-diet controls

- angiography: a procedure that provides a picture of the heart, its vessels, and the chambers by cardiac catheterization (a tube put in the heart)
- catherization: a thin flexible tube that can be inserted into a blood vessel, and guided through to a certain body organs. A doctor observes by using a fluoroscope (lite can X-ray except gives live photos)
- percutaneous transluminal coronary angioplasty (baloon angioplasty): threading a baloon- tipped catheter, through the body to the site of a blockage. As the baloon is inflated, it pushes the plaque a gainst the artery wall, opening a path for the blood to flow through
