Common mistakes
- Ureter and urethra are not the same word. Mixing them is a 0 on a 1-mark label.
- Ultrafiltration is not selective reabsorption and it is not ADH. Wrong named process, wrong place.
- Selective reabsorption is not "the glomerulus choosing". The glomerulus filters by size; the tubule chooses what to take back.
- ADH does not "add water from the bladder into the blood". Water is reabsorbed from the nephron into the blood.
