30
Q

formed in the kidneys through the filtration of blood.

A

Urine

31
Q

Characteristics of the muscular walls of ureters that pushes the urine toward the urinary bladder

A

Peristaltic contractions

hydrostatic pressure and gravity also contribute.

32
Q

Urinary bladder stores urine and expels it into the

A

Urethra

33
Q

a hollow, distensible muscular organ situated in the pelvic cavity posterior to the pubic symphysis

A

Urinary Bladder

34
Q

URINARY BLADDER:

In males, it is directly _____ to the _____; in females, it is ______ to the ______ and _____ to the ________.

A

In males, it is directly ANTERIOR to the RECTUM; in females, it is ANTERIOR to the VAGINA and INFERIOR to the UTERUS.

35
Q

Two sphincters control the emptying of the urine from the bladder.

A

Bladder Neck Sphincter
Urethral Sphincter

36
Q

sphincter under involuntary (autonomic) control

A

Bladder Neck Sphincter

37
Q

sphincter has both voluntary and involuntary components

A

Urethral Sphincter

38
Q

A

Cortical Nephron

39
Q

15–20% of the nephrons are

A

Juxtamedullary nephron

40

A

Cortical Nephron

41
Q

Their renal corpuscles lie deep in the cortex, close to the medulla, and they have a long nephron loop that extends into the deepest region of the medulla.

A

Juxtamedullary Nephron
