THE CIRCULATORY SYSTEM

FUNCTIONS

• Deliver materials
• Removes waste
• Regulates body temperature
• Fights disease

ORGANS

• Heart
• Blood vessels- veins, arteries,capillaries

ORGAN FUNCTIONS

• Heart-pumps blood-upper two chambers, atria, receive blood from body- lower two chambers, called ventricles, pump blood to the body
• Blood vessels- carry blood from the heart to the body and back again.

HOW IT WORKS WITH OTHER SYSTEMS

• It works with every organ system in your body except the integumentary system by delivering blood to the organs.
• It especially works with the respiratory system, because your lungs exchange carbon dioxide in your blood with oxygen.

HEART FAILURE

• Heart failure is when the heart can't pump enough blood to the body
• Can't be completely cured,though there are treatments that may help
• At risk people-people with coronary heart disease, high blood pressure, and diabetes
• To lower your risk, avoid illegal drugs, avoid smoking, be at a healthy weight, be active, and follow a heart healthy diet

HYPERTENSION

• Dangerously high blood pressure
• Chronic
• Can be prevented and treated by eating less salt and more healthy foods, exercising regularly, and taking medication that lowers blood pressure.
• People at high risk often: eat too much sodium, not enough potassium,don't exercise enough, drink too much alcohol, or are stressed.

FACTS

• The sound of your heartbeat is caused by your valves closing.
• The largest artery is your aorta
• The components of blood are plasma, red blood cells, white blood cells, and platelets.
