What happens to the walls of distal convoluted tubule (DCT) of a nephron when vasopressin is released by pituitary into the blood stream?

Explanation

**Step-by-Step Solution:**

1. **Understanding Vasopressin**: Vasopressin, also known as antidiuretic hormone (ADH), is a hormone released by the pituitary gland. It plays a crucial role in regulating water balance in the body.

2. **Stimulus for Release**: The release of vasopressin is triggered by an increase in plasma osmolarity, which indicates dehydration or a higher concentration of solutes in the blood.

3. **Effect on Distal Convoluted Tubule (DCT)**: Once vasopressin is released into the bloodstream, it travels to the kidneys, specifically targeting the distal convoluted tubule (DCT).
