Cards

Term
B-cells
Definition
cells in the islets of Langerhans in the pancreas that secrete insulin
Term
BMI
Definition
a measurement of body overweight or obesity determined by dividing weight (kg) by height (m) squared. highly correlated with body comp
Term
arteriosclerosis
Definition
codition that involves loss of elasticity, thickening, and hardening of the arteries
Term
atherosclerosis
Definition
form of arteriosclerosis that involves changes in the lining of the arteries and plaque accumulation, leading to progressive narrowing of the arteries
Term
blood lipids
Definition
bloodborne fats, such as triglycerides and cholesterol
Term
congenital heart disease
Definition
a heart defect present at birth that occurs from abnormal prenatal development of the heart or associated blood vessels. aka congenital heart defect
Term
coronary heart disease
Definition
disease characterized by pathological changes in coronary arteries that supply blood flow
Term
diabetes mellitus
Definition
disorder of carbohydrate metabolism characterized by hyperglycemia (high blood sugar) and glycosuria (presence of sugar in the urine). develops when there is inadequate production of insulin by the pancreas or inadequate utilization of insulin by the cells
Term
endothelium
Definition
layer of thin cells that line the lumen of the blood vessels
Term
fatty streaks
Definition
early lipid deposits within blood vessels
Term
heart failure
Definition
clinical condition in which the myocardium becomes too weak to maintain adequate cardiac output to meet the body's oxygen demands; heart failure usually results from the heart's being damaged or overworked
Term
hemorrhagic stroke
Definition
involves bleeding within the brain, which damages nearby brain tissue
Term
high-density lipoprotein (HDL-C)
Definition
aka scavenger. theorized to remove cholesterol from the arterial wall and transport it to the liver to be metabolized
Term
hyperinsulinemia
Definition
high levels of insulin in the blood
Term
hypertension
Definition
abnormally high blood pressure. adults: systolic= 140 mmHg or higher, diastolic= 90 mmHg or higher
Term
impaired fasting glucose
Definition
a plasma glucose level between 110 and 125 mg/dL following an 8 h fast
Term
impaired glucose tolerance
Definition
abnormal glucose response to an oral glucose load (glucose tolerance test), sometimes seen as a precursor to diabetes
Term
insulin resistance
Definition
a deficient target cell response to insulin
Term
insulin sensivity
Definition
an index of the effectiveness of a given insulin concentration on the disposal of glucose
Term
insulin-dependent diabetes mellitus
Definition
one of two major categories of diabetes mellitus that is caused by the inability of the pancreas to produce sufficient insulin as a result of failure of the B-cells in the pancreas. type 1 diabetes
Term
ischemia
Definition
a temporary deficiency of blood to a specific area of the body
Term
ischemic stroke
Definition
brain tissue damage resulting from the lack of oxygen to an area of the brain. may be caused by narrowing or blockage of blood vessels in the area
Term
lipoproteins
Definition
the proteins that carry blood lipids
Term
low-density lipoprotein cholesterol (LDL-C)
Definition
a cholesterol carrier theorized to be responsible for depositing cholesterol in the arterial wall
Term
low-intensity aerobic exercise
Definition
aerobic exercise performed at low intensity, theoretically to cause the body to burn a higher percentage of fat
Term
lower body (gynoid) obesity
Definition
obesity that follows the typically female pattern of fat storage,in which fat is stored primarily in the lower body, particularly in the hips, buttocks, and thighs. aka pear-shaped obesity
Term
metabolic syndrome
Definition
link coronary artery disease, hypertension, type 2 diabetes, and upper body obesity to insulin resistance and hypeinsulinemia. aka syndrome X and civilization syndrome
Term
myocardial infarction
Definition
death of heart tissue that results from insufficient blood supply to part of the myocardium
Term
non-insulin-dependent diabetes mellitus
Definition
one of two major categories of diabetes mellitus that is caused by the ineffectiveness of insulin to facilitate the transport of glucose into the cells and is a result of insulin resistance. aka type 2 diabetes
Term
obesity
Definition
an excessive amount of body fat, generally more than 25% in men and 35% in women; bmi of 30 or greater
Term
overweight
Definition
body weight that exceeds the normal or standard weight for a particular individual based on height, sex, and frame size; bmi=25 to 29.9
Term
pathophysiology
Definition
the physiology of a specific disease
Term
peripheral vascular disease
Definition
diseases of the systemic arteries and veins, esp those to the extremities, that impede adequate blood flow
Term
plaque
Definition
a buildup of lipids, smooth muscle cells, connective tissue, and debris that forms at the site of injury to an artery
Term
platelet-derived growth factor
Definition
a substance released by blood platlets that promotes the migration of smooth muscle cells from the media of an artery into the intima
Term
prediabetes
Definition
impaired fasting glucose, impaired glucose tolerance, or both, but not truly diabetic
Term
primary risk factors
Definition
risk factors that have been conclusively shown to have a strong association with a certain disease. ex: coronary artery disease primary risk factors are smoking, hypertension, high blood lipid levels, obesity, and physical inactivity
Term
rheumatic heart disease
Definition
form of valvular heart disease involving streptococcal infection that has caused acute rheumatic fever, typically in children between 5 and 15
Term
risk factor
Definition
a predisposing factor statistically linked to the development of a disease, such as coronary artery disease
Term
spot reduction
Definition
the practice of exercising a specific area of the body, theoretically to reduce locally stored fat
Term
stroke
Definition
a cerebral vascular accident, a condition in which blood supply to some part of the brain is impaired, typically caused by infarction or hemorrhage, so that the tissue is damaged
Term
thermic effect of a meal (TEM)
Definition
the energy expended in excess of resting metabolic rate associated with digestion, absorption, transport, metabolism, and storage of ingested food
Term
thermic effect of activity(TEA)
Definition
the energy expended in excess of resting metabolic rate to accomplish a given task or activity
Term
type 1 diabetes
Definition
sudden onset during childhood or young adulthood and leads to almost total insulin deficiency, usually as insulin-dependent mellitus or juvenile-onset diabetes
Term
type 2 diabetes
Definition
onset is more gradual and the causes are more difficult to establish than in type 1 diabetes. characterized by impaired insulin secretion, impaired insulin action, or exclusive glucose output from the liver. aka non-insulin-dependent diabetes mellitus
Term
upper body (android) obesity
Definition
obesity that follows the typically male pattern of fat storage, in which fat is stored primarily in the upper body, particularly in the abdomen
Term
valvular heart disease
Definition
a disease involving one or more of the heart valves. ex: rheumatic heart disease
Term
very low density lipoprotein cholesterol (VLDL-C)
Definition
the cholesterol carried by VLDL
