Each nephron has a cup shaped upper end called _________, which contains a _________

Options

A. Bowman's capsule, Ampulla
B. Capillaries, Bowman's capsule
C. Ampulla, Glomerulus
D. Bowman's capsule, Glomerulus

Explanation

**Step-by-Step Solution:**

1. **Identify the Structure of the Nephron**: Each nephron, which is the functional unit of the kidney, has a specific structure. The upper end of the nephron is cup-shaped.

2. **Name the Cup-Shaped Structure**: The cup-shaped upper end of the nephron is called the "Bowman's capsule." This structure plays a crucial role in the filtration process of blood.

3. **Identify What is Contained Within the Cup**: Inside the Bowman's capsule, there is a network of small blood vessels known as the "glomerulus." The glomerulus is responsible for filtering blood to form urine.

4. **Final Answer**: Therefore, the complete answer to the question is: Each nephron has a cup-shaped upper end called the **Bowman's capsule**, which contains a **glomerulus**.
