BUILD A PROCESS

Follow urine from nephron to outside

Separate the urine route from the blood route.

Build a process

Use the up and down buttons to build the sequence, then check your reasoning. Some biological events overlap; follow the simplified pathway described here.

  1. 1
    Urethra
  2. 2
    Urinary bladder
  3. 3
    Ureter
  4. 4
    Renal calyces and pelvis
  5. 5
    Collecting duct
Read the complete pathway
  1. Collecting duct. Final water adjustments occur under hormonal influence.
  2. Renal calyces and pelvis. Urine drains into the collecting region.
  3. Ureter. Peristalsis carries urine towards the bladder.
  4. Urinary bladder. A muscular reservoir stores urine.
  5. Urethra. Urine leaves the body.

Explain what you observed

Does the renal vein carry urine?

Model

From filtrate to urine

Investigate water reabsorption and urine output.

Sort & explain

Filtration, reabsorption or secretion?

Track directions across the nephron.

Model

Thermoregulation and negative feedback

Change a temperature disturbance and inspect the opposing response.
