specific gravity
|
weight of a liquid compared to pure water, which has a specific gravity of 1.0; any solute added to
water will increase its specific gravity |
62. |
systemic edema
|
increased fluid retention in the interstitial spaces and cells of the body; can be seen as swelling
over large areas of the body, particularly the lower extremities |
63. |
trigone
|
area at the base of the bladder marked by the two ureters in the posterior-lateral aspect and the
urethral orifice in the anterior aspect oriented like points on a triangle |
64. |
tubuloglomerular feedback
|
feedback mechanism involving the JGA; macula densa cells monitor Na+ concentration in the terminal
portion of the ascending loop of Henle and act to cause vasoconstriction or vasodilation of afferent
and efferent arterioles to alter GFR |
65. |
urethra
|
transports urine from the bladder to the outside environment |
66. |
urinalysis
|
analysis of urine to diagnose disease |
67. |
urochrome
|
heme-derived pigment that imparts the typical yellow color of urine |
68. |
vasa recta
|
branches of the efferent arterioles that parallel the course of the loops of Henle and are continuous
with the peritubular capillaries; with the glomerulus, form a portal system |
