name all of the arteries in the heart

aorta pulmonary artery

name all of the valves in the heart

tricuspid bicuspid pulmonary aortic

what is the function of the inferior and superior vena cava

transport deoxygenated blood from the body to the right atrium

what is the function of the aorta

transport oxygenated blood from the left ventricle to the body

what is the function of the pulmonary arteries

transport deoxygenated blood from the right ventricle to the lungs

what is the function of the pulmonary veins

transport oxygenated blood from the lungs to the left atrium

where is the tricuspid valve

between the right atrium and ventricle

pulmonary vein

what is CHD

the narrowing or blocking of arteries due to atherosclerosis

what causes CHD

atherosclerosis-build up of fatty deposits on walls

what are the risk factors for CHD(3)

smoking hypertension diabetes

3 symptoms of CHD

fatigue angina heart attacks

what lifestyle changes are used to treat CHD

eating well exercise no smoking

what medications can be used to treat CHD

blood thinners statins and beta blockers

what do statins do

lower LDL cholesterol in the body stopping atherosclerosis

what are beta blockers and what do they do

block stress hormones to reduce the hearts rate and workload

effect on (P)IES CHD

angina and fatigue make walking long distances and exercising difficult

effect on P(I)ES CHD

reduced blood flow to the brain can increase risk of dementia and cognitive decline

effect on PI(E)S CHD

heart attacks may cause depression and there may be anxiety surrounding medications and treatment

effect on PIE(S) CHD

individuals may feel isolated due to physical limitations and reluctance to share anxiety with others

what is hypertension

high blood pressure

what organs does hypertension affect and how

heart kidney and brain due to strain on blood vessels

what can hypertension lead to

heart attacks and strokes

what is hypertension caused by

what blood pressure is deemed unhealthy/hypertension

140/90

what lifestyle changes are used to treat hypertension

low salt diet stop smoking lose weight

what medications are used to treat hypertension

calcium channel blockers and diuretics

how do calcium channel blockers help treat hypertension

they relax blood vessels and reduce strain

hypertension effects on daily life

daily medications and making conscious decisions about what to eat

hypertension (P)IES

diuretic medications cause frequent urination and reduced oxygen delivery make walking and climbing hard

hypertension effects on PI(E)S

health anxiety caused by higher chances of health crises

hypertension effects on PIE(S)

social situations involving food become frustrating
