carcinoma that creates finger like projections in lumen or infiltrate the bladder wall
bladder cancer
42
bladder cancer can be caused by
chemical exposures, smoking, parasitic infection
43
looks like punctuate, coarse, or linear calcifications encrusted in the surface of the tumor
bladder cancer
44
blood clot in renal vein (renal vein thrombosis) occurs most frequently with
children who are dehydrated
45
radiographically acute total occlusion, kidney enlargement with monomal or no opacification
renal vein thrombosis
46
rapid deterioration in kidney function resulting in accumulation of nitrogen, containing wastes in the blood and ammonia smelling breath
acute renal failure
47
chronic renal failure is also called
uremia
48
clear nitrogen containing wastes from blood leading to excessive levels or urea and creatine in the blood
chronic renal failure
49
which valve lies between the right and left atria and ventricles that permits blood flow in one direction and are made of flaps of endocardium anchored to papillary muscles
atrioventricular
50
How to describe the pulmonary circulatory loop
blood circulates to the lungs, to release the carbon dioxide and pick up new oxygen by the right side of the heart
51
The contraction of the heart muscle is measured by
systolic equipment
52
The narrowing of the coronary arteries causing oxygen deprivation of the myocardium and ischemic heart disease is referred to as
coronary artery disease
53
Condition characterized by an inability of the heart to propel blood at a sufficient rate and volume provide adequate supply resulting in tissue necrosis
congestive heart failure
54
abnormal accumulation of fluid in the extravascular pulmonary tissue causing left sided heart failure
pulmonary edema
55
condition described as a localized dilation of an artery often seen radiographically as curvilinear calcifications in the vessel wall especially in the abdominal region
aneurysm
56
abnormal communication between the 2 atria causing increased pulmonary blood flow enlarging the right ventricle and pulmonary vessels
atrial septal defect
57
rib notching is a sign of which condition
coarctation of the aorta

pulmonary edema
67
bat wing effect is known as
pulmonary edema
68
elevated blood pressure, leading cause of strokes and CHF
hypertension
69
in order for someone to be considered with hypertension their blood pressure would be
140 over 90
70
left ventricle contraction, greatest pressure in peripheral arteries
systolic BP
71
left ventricle relaxation
diastolic BP
72

malignant hypertension
73
gradual increase onset of hypertension
benign hypertension
74
narrowing of systemic blood vessels and an increase resistance to blood flow from long standing hypertension
hypertensive heart disease
75
left ventricular failure (HTN heart disease) can lead to
increased pulmonary venous pressure and congestive heart failure
76
localized dilation of an artery, most commonly involves abdominal aorta
aneurysm
77
results of artherosclerosis, syphilis, infections, trauma, congenital defects like Marfan's syndrome
aneurysm
78
moving blood clot
embolism
79
when is thrombosis considered normal
blood clot is normal for when the body is trying to stop a hemorrhage from a vessel
80
where does an emboli often originate and where does it get lodged
originates in the vein and then lodges in the artery of the heart
81
a vessel extends from the bifurcation of the right pulmonary artery to join the aorta just distal to the subclavian artery
patent ductus arteriosis
82
cardiomegaly with enlargement of the left atrium
patent ductus arteriosis

accumulation of fluid within the pericardial space surrounding the heart
pericardial effusion
94
deep vein thrombosis primarily involves
lower extremity
95
