Q

Dilation of the renal collection system

A

Hydronephrosis

17
Q

Portion of the renal tubule lying between the proximal and distal convoluted portions; reabsorption of fluid, sodium, and choride occurs in the proximal convoluted tubule and the loop of Henle

A

Loop of henle

18
Q

Receive urine from the minor calyces to convey to the renal pelvis

A

Major calyces (also knows as the infundibula)

19
Q

The inner portion of the renal parenchyma that contains the loop of Henle

A

Medulla (also known as the pyramid)

20
Q

Receive urine from the renal pyramids, form the border of the renal sinus

A

Minor calyces

21
Q

Right posterior subhepatic space located anterior to the kidney and inferior to the liver where fluid may accumulate

A

Morison’s pouch

22
Q

Functional uit of the kidney; includes a renal corpuscle and a renal tubule

A

Nephron

23
Q

Interruption in the normal development of the kidney resulting in absence of the kidney; may be unilateral or bilateral

A

Renal agenesis

24
Q

First layer adjacent to the kidney that forms a tough, fibrous covering

A

Renal capsule

25
Q

Part of the nephron that consists of Bowman’s capsule and the glomerulus

A

Renal Corpuscle

26
Q

A kidney that is not located in its usual position, usually found in the pelvic cavity

A

Renal ectopia (ectopic kidney)

27
Q

Area in the midportion of the kidney wher the renal vessels and ureter enter and exit

A

Renal Hilum

28
Q

Incomplete development of the kidney, usually with fewer than five calyces

A

Renal hypoplasia

29
Q

Area in the midportion of the kidney that collects urine before entering the ureter

A

Renal pelvis

30
Q

One of several conical masses of tissue that form the kidney medulla. The base of each pyramid adjoins the kidney’s cortex; the apex terminates at a renal calyx. The pyramids consist of the loops of Henle and the collecting tubules of the nephrons

A

Renal Pyramid

31
Q

Central area of the kidney that includes the calyces, renal pelvis, renal vessels, fat, nerves, and lymphatics

A

Renal sinus

32
Q

Space behind the peritoneal lining of the abdominal cavity

A

Retroperitoneuam

33
Q

Laboratory tests that measure how much dissolved material is present in the urine

A

Specific gravity

34
Q

Retroperitoneal structures that exit the kidney to carry urine from the urinary bladder

A

Ureters

35
Q

Small membranous canal that excretes urine from the urinary bladder

A

Urethra

36
Q

Muscular retroperitoneal organ that serves as a reservoir for urine

A

Urinary bladder

37
Q

Stone within the urinary system

A
