20
Q

veins located at the border of the renal cortex and renal medulla

A

arcuate vein

21
Q

veins of the renal circulation which drain the renal lobes

A

interlobar vein

22
Q

The main blood vessel that carrying blood away from the kidney and ureter to the inferior vena cava

A

renal vein

23
Q

brings filtered blood from the glomerulus to the rest of the kidney and back to the general circulation

A

efferent arteriole

24
Q

bring blood into your kidney’s glomerulus

A

afferent arteriole

25
Q

filters by removing waste and extra water from your blood, uniquely situated between two resistance vessels

A

glomerulus

26
Q

connected directly to the glomerulus. Functions in reabsorption and secretion

A

proximal convoluted tubule

27
Q

part of nephron loop going towards medulla

A

descending limb

28
Q

part of nephron loop going away from medulla

A

ascending limb

29
Q

located between PCT and DCT

A

nephron loop

30
Q

follows right after ascending limb of nephron loop, connecting to collecting duct

A

distal convoluted tubule

31
Q

the blood-filtering component of the nephron of the kidney. It consists of a glomerulus and a glomerular capsule

A

renal corpuscle

32
Q

a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis

A

collecting duct

33
Q

the most distal portion of the collecting duct, empty into a minor calyx

A

papillary duct

34
Q

a cup-like sac at the beginning of the tubular component of a nephron

A

glomerular capsule

35
Q

space in between the glomerulus and glomerular capsule

A

glomerular space

36
Q

parietal layer of glomerular capsule

A

glomerular capsule outer layer

37
Q

inner visceral layer which completely encircle the glomerular capillaries. Comprised of specialized stellate epithelial cells called podocytes

A

visceral layer

38
Q

opening of the ureters into bladder

A

ureteral orifices

39
Q

muscle which forms a layer of the wall of the bladder

A

detrusor muscle

40
Q

a series of ridges produced by folding of the wall of the bladder

A

rugae

41
Q

sphincter that consists of smooth muscle and is continuous with the bladder detrusor

A

internal urethral sphincter

42
Q

tube through which urine leaves the body. It empties urine from the bladder

A

urethra

43
Q

a triangular region or tissue, particularly the area at the base of the urinary bladder, between the openings of the ureters and urethra

A

trigone
