Module 14: Reducing Your Risk of Cardiovascular Disease and Cancer and Minimizing Your Risk for Diabetes Flashcards
(104 cards)
define global burden of disease (GBD)
- method of quantifying the burden of premature morbidity, disability, and death for a given disease or disease groups
define disability adjusted years (DALYs)
- how global burden of disease is measured
- measure of overall disease burden expressed as the number of years lost due to ill health
what is the leading cause of death in the world
- cardiovascular disease
who has the worst prognosis once cardiovascular disease or cancer are diagnosed
- people living in poverty
define chronic disease
- illness that is prolonged
- does not resolve spontaneously
- rarely cured
- cardiovascular disease and cancer
define cardiovascular disease (CVD)
- disease of the heart and blood vessels
what did the AHA report about CVD death rates in 2015
- death rates from CVD had declined by 33% in the last decade
how many death is the US have CVD as the underling cause
- one third
define ideal cardiovascular health (ICH)
- absence of clinical indicators of CVD
- presence of certain behavioral and health metrics
what are the 7 behavioral and health factors present in ideal cardiovascular health (ICH)
- not smoking
- recommended physical activity
- healthy diet pattern
- healthy weight
- having optimal total cholesterol without medication
- having optimal blood pressure without medication
- having optimal fasting blood glucose without medication
define cardiovascular system
- organ system consisting of the heart and blood vessels
- transport nutrients, oxygen, hormones, metabolic wastes, and enzymes throughout the body
- regulates body temperature, cellular waster levels, and acidity levels of body components
how many quarts of blood does a human contain
- 6 quarts
define atria and ventricles
- atria: two upper chambers that receive blood
- ventricles: two lower chambers that pump blood through the blood vessels
what are the 4 steps in heart function
- deoxygenated blood enters right atrium
- blood moves to right ventricle and is pumped through the pulmonary artery to the lungs where it receives oxygen
- oxygenated blood returns to the left atrium
- blood moves to left ventricle and is pumped through the aorta to the body
define arteries, arterioles, veins, and venules
- arteries: carry blood away from the heart
- arterioles: branches of arteries
- veins: carry blood back to the heart
- venules: branches of veins
which artery is the only one to carry deoxygenated blood
- pulmonary artery
defien capillaries
- tiny blood vessels that branch out from arterioles and venules
- thin walls that allow exchange of oxygen, carbon dioxide, nutrients, and waste products
define the sinoatrial node (SA node)
- cluster of electric pulses
- pacemaker of the heart
- where electrical signal starts that pumps the heart
- located in the right atrium
define hypertension
- sustained high blood pressure
- known as silent killer because it has few overt symptoms
define systolic blood pressure
- upper number in fraction
- indicates pressure of walls of arteries when heart contracts
- increases with age
define diastolic blood pressure
- lower number in fraction
- indicates pressure of walls of arteries when heart relaxes
- increases until age 55, then decreases
define arteriosclerosis
- general term for thickening and hardening of the arteries
define atheroscleosis
- type of arteriosclerosis
- deposits of plaque (fatty substances) in the inner lining of an artery
define ischemia
- reduced oxygen supply to a body part or organ
