MICTURITION

23
Q

START IN THE RENAL PELVIS AND END IN THE URINARY BLADDER

A

URETER

24
Q

HOLLOW ORGAN THAT VARIES IN SIZE AND POSITION; EMPTY – FLOOR OF THE PELVIC CAVITY; FULL – ABDOMINAL CAVITY

A

A

PELVIC URETHRA

26
Q

ARE CELLS IN THE BOWMAN’S CAPSULE IN THE KIDNEYS THAT WRAP AROUND CAPILLARIES OF THE GLOMERULUS

A

PODOCYTES

27
Q

CELLS SENSE CHANGES IN SODIUM CHLORIDE LEVEL, AND WILL TRIGGER AN AUTOREGULATORY RESPONSE

A

MACULA DENSA

28
Q

SECRETE RENIN

A

JUXTAGLOMERULAR CELLS/ GRANULAR CELLS

29
Q

Kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney.

A

Glomerular filtration

30
Q

the pressure tending to force fluid out of the capillary

A
  • effective filtration pressure
31
Q

glomerular filtration barrier acts much like a -

A

Sieve

32
Q

all substances
up to a molecular weight of about –pass through the barrier

A

65,000

33
Q

process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron

A

Selective tubular reabsorption

34
Q

used to remove drugs, toxins and poisons,
or other natural compounds in excessive
amounts (such as potassium (K+),
hydrogen (H+), and urea)

A

Selective tubular secretion

35
Q

IN Avian Urinary System, kidneys lie on the __

A

ventral surface of the synsacrum; divided into cranial, middle, and caudal lobes

36
Q

IN Avian Urinary System, there are no what?

Q

Filters small solutes from the blood

A

Glomerulus

47
Q

Reabsorbs solutes and water from the filtrate

A

Collecting duct
