taking carotid pulse, circulation of blood, the heart, radial pulse, normal heart anatomy, cut section, effects of age on blood pressure, heart disease, aging, atherosclerosis, aging some changes, in the heart, blood vessels, occur, many others, modifiable factors, not treated, lead to heart disease, background, heart has two sides, right side pumps blood, lungs to receive oxygen, get rid of carbon dioxide, left side pumps oxygen-rich blood, blood flows out, the heart, arteries, branch out, get smaller, smaller, they go, tissues, tissues, become tiny capillaries, capillaries, blood gives up oxygen, nutrients, tissues, receives carbon dioxide, wastes back, tissues, vessels begin to collect together into larger, larger veins, return blood, heart, aging causes, in the heart, blood vessels, heart, blood vessel diseases, the most common disorders, in the elderly, aging changes, heart, normal changes, in the heart include deposits, the "aging pigment", lipofuscin, heart muscle cells degenerate slightly, valves inside the heart, control the direction of blood flow, thicken, become stiffer, a heart murmur, valve stiffness is fairly common, in the elderly, heart has a natural pacemaker system that controls heartbeat, the pathways of this system, develop fibrous tissue, fat deposits, natural pacemaker, sa node, loses some of its cells, a slightly slower heart rate, heart changes cause the ecg of a normal, healthy aged person to be slightly different than the ecg of a healthy younger adult, abnormal rhythms, arrhythmias, atrial fibrillation, common in older people, heart disease, a slight increase, in the size, the heart, the left ventricle, not uncommon, heart wall thickens, blood that the chamber, hold, decrease despite the increased overall heart size, heart, fill more slowly, blood vessels, main artery, heart, aorta, becomes thicker, stiffer, less flexible, related to changes, in the connective tissue, the blood vessel wall, makes the blood pressure higher, makes the heart work harder, lead to hypertrophy, thickening, the heart muscle, arteries also thicken, stiffen, most elderly people experience a moderate increase in blood pressure, receptors, baroreceptors, monitor the blood pressure, make changes to help maintain a fairly constant blood pressure, a person changes positions, baroreceptors, become less sensitive, aging, explain the relatively common finding of orthostatic hypotension, a condition, the blood pressure falls, a person goes from lying, sitting to standing, resulting in dizziness, wall, the capillaries thickens slightly, a slightly slower rate of exchange of nutrients, wastes, blood, blood changes slightly, aging causes, a normal reduction in total body water, part of this, less fluid, in the bloodstream, blood volume decreases, number of red blood cells, correspondingly, hemoglobin, hematocrit levels, contributes to fatigue, the white blood cells stay, same levels, certain white blood cells important to immunity, lymphocytes, decrease in number, ability to fight off bacteria, reduces the ability to resist infection, effect of changes, under normal circumstances, heart continues to adequately supply all parts, an aging heart slightly less able to tolerate increased workloads, changes reduce this extra pumping ability, reserve heart function, the things, increase heart workload include illness, infections, emotional stress, injuries, extreme physical exertion, certain medications, common problems, heart, blood vessel diseases, fairly common in older people, common disorders include high blood pressure, orthostatic hypotension, arteriosclerosis, hardening, the arteries, very common, fatty plaque deposits inside the blood vessels cause it to narrow, totally block blood vessels, coronary artery disease is fairly common, angina, chest pain, temporarily reduced blood flow, heart muscle, shortness of breath, exertion, heart attack, result from coronary artery disease, abnormal heart rhythms, arrhythmias, various types, heart failure is also very common, in the elderly, in people older than 75, heart failure occurs 10 times more often than in younger adults, valve diseases, fairly common, aortic stenosis, narrowing, the aortic valve, common valve disease, in the elderly, anemia, possibly related to malnutrition, chronic infections, blood loss, gastrointestinal tract, a complication of other diseases, medications, transient ischemic attacks, tia, strokes, occur, blood flow, brain is disrupted, the heart, blood vessels, peripheral vascular disease, resulting in claudication, intermittent pain, in the legs, walking, varicose veins, blood clots, thrombophlebitis, deep vein thrombosis, prevention, circulatory system, heart, blood vessels, heart disease risk factors, control over include high blood pressure, cholesterol levels, diabetes, obesity, smoking, eat a heart-healthy diet, reduced amounts of saturated fat, cholesterol, control weight, treatment of high blood pressure, high cholesterol, diabetes, minimize, stop smoking, moderate exercise is one, the best things, to keep heart, rest of body, healthy, consult, beginning a new exercise program, exercise moderately, capabilities, it regularly, people who exercise have less body fat, smoke less, have less blood pressure problems, less heart disease than people who, not exercise, exercise helps, prevent obesity, helps people, diabetes control blood sugar, exercise maintains maximum abilities, reduces stress, related topics, aging changes in organs, tissues, cells, aging changes, in the lungs, aging changes in vital signs.
