reabsorption

A

tubules

29
Q

blood is initially filtered; surrounded by a glomerular capsule (bowman’s capsule) which is the proximal portion of each nephron collecting filtrate.

The filtrate is termed urine by the time it reaches the minor calyx. Between the bowman’s capsule and the minor calyces, more than 99% of the filtrare is reabsorved into the kidneys venous system.

Glomerulus

30
Q

supply blood to the glomeruli

Afferent arterioles

31
Q

take blood away

A

Efferent arterioles

32

uteropelvic junction
brim of the pelvis
ureterovisceral junction

36

A

Urinary bladder

37
Q

triangular portion of the bladder; muscular area formed by the entrance of the two ureters from behind and the exit site of the urethra; firmly attached to the floor of the pelvis
