Non-Communicable Diseases

Non-Communicable Disease Diseases that can not be spread from one person to another. They are not caused by microorganisms / pathogens. They can be treated but not cured There is no immunity to non- communicable disease

Causes of Non-Communicable Disease Heredity- passed on from parent to child  cystic fibrosis and down syndrome  studies have shown that there are inherited tendencies Environment  Where you live or work may cause a non-communicable disease

Causes of Non-Communicable Disease Lifestyle  Poor health habits- tanning beds, smoking, drinking, poor diet, lack of exercise, and emotional stress

Preventing Non-Communicable Disease Balanced diet Regular exercise Avoid tobacco, alcohol, and other drugs Regular check ups can identify early warnings of disease Manage stress levels

Circulatory System Heart: a four chambered muscular pump. Arteries: supply oxygenated blood to the entire body (cells, muscles, organs). Veins: take de-oxygenated blood from the body and back to the lungs and heart.

Circulatory System Pulmonary Circuit: carries blood to the lungs for gas exchange, then returns to the heart (serviced by the right side of heart). Systemic Circuit: supplies blood to every organ of the body (serviced by the left side of the heart).

The Heart

The Path of Blood 1. vena cava 2. right atrium 3. right ventricle 4. pulmonary artery (to lungs) 5. gets oxygen from the lungs 6. pulmonary vein (from lungs) 7. left atrium 8. left ventricle 9. aorta (to the rest of the body)

Amazing Heart Facts Your heart is about the same size as your fist. An average adult body contains about five quarts of blood. All the blood vessels in the body joined end to end would stretch 62,000 miles or two and a half times around the earth. The heart circulates the body's blood supply about 1,000 times each day. The heart pumps the equivalent of 5,000 to 6,000 quarts of blood each day.

Heart / Cardiovascular Disease Disease of the heart and blood vessels #1 Killer in the USA (men & women) About 610,000 people die of heart disease in the US every year–that’s 1 in every 4 deaths Every year about 735,000 Americans have a heart attack.

Cardiovascular Disease Hypertension: High blood pressure Caused by excessive pressure against the arterial walls No cure

Cardiovascular Disease Factors of Hypertension: StressHeredity Sodium intake

Cardiovascular Disease Treatment of Hypertension: 90% can be controlled Desirable weight Reduce sugar, cholesterol, sodium, and saturated fat intake Regular exercise

Cardiovascular Disease Arteriosclerosis- the thickening and hardening of the arterial walls. The walls become hard and lose their elasticity. Atherosclerosis- the build up of plaque (fatty deposits) on the inner lining of the arteries.

Atherosclerosis

Heart Attack Heart Attack- cells in the heart muscle die resulting from the lack of oxygen and nutrients due to a blockage in a coronary artery. Symptoms: Chest pain or discomfort in the arms, back, neck, jaw, or upper stomach; shortness of breath. Nausea, lightheadedness, or cold sweats. P6ig9Q P6ig9Q

Heart Attack Fibrillation- rhythmic disturbance in heart resulting from muscle fiber that is out of synchronization. Stroke- blood supply to the brain is cut off, resulting in brain cell damage. Common symptoms of stroke: face drooping, arm weakness, speech difficulty. Call 911 even if symptoms disappear.
