To solve the problem, we need to identify which part of the nephron functions as the filtration unit.
1. Filtration Unit in the Kidney:
The filtration unit of the kidney is actually the Glomerulus. It is a network of capillaries located within the **Bowman's capsule**.
2. Explanation:
The process of filtration in the kidney begins when blood flows into the glomerulus from the renal artery. The pressure forces water, small molecules, and waste products from the blood to pass into the Bowman's capsule, which collects the filtrate.
Final Answer:
The correct answer is $ {\text{Glomerulus}} $.
