Name and explain the process that occurs in distal convoluted tube during the formation of urine.

Explanation

**Step-by-Step Text Solution:**

1. **Identify the Process**: The process that occurs in the distal convoluted tubule during the formation of urine is called **tubular secretion**.

2. **Definition of Tubular Secretion**: Tubular secretion is the process where certain substances are actively transported from the blood into the tubular fluid. This is crucial for the removal of waste products and excess ions from the bloodstream.

3. **Mechanism of Tubular Secretion**: In the distal convoluted tubule, unwanted ions (such as potassium and hydrogen ions), waste products (like urea and ammonia), and certain drugs are secreted from the peritubular capillaries into the tubular lumen. This process helps in maintaining the body's electrolyte balance and pH levels.
