2. What are the effects of the following hormones on the function of the distal convoluted tubule?
- ADH:
- Aldosterone:
3. Regarding the Bowman's capsule, answer the following:
- What drives the fluid from the glomerulus into the Bowman's capsule?
- What substances are moved from the glomerulus into the Bowman's capsule?
- What substances remain in the blood?
