🫘 The Kidney & Nephron
Remember: Nephron: Filtration → Selective Reabsorption → Excretion | ADH controls water balance | Glucose in urine = diabetes
Practice questions for Water Regulation
Where does the filtration of blood take place in the kidney?
Describe the process of selective reabsorption in the kidney and explain why it is important.
Quick recall flashcards
What is ADH and what does it do?
ADH (antidiuretic hormone) is released by the pituitary gland. It makes the kidneys reabsorb more water from the filtrate back into the blood, producing smaller amounts of more concentrated urine.
What is osmoregulation?
Osmoregulation is the control of the water content and ion concentration of the blood. The kidneys are the main organs responsible for this.
