The process that pushes out water and other dissolved materials from blood in the glomerulus is

Options

A. Dialysis
B. Secretion
C. Filtration
D. Ultrafiltration

Answer

**Step-by-Step Solution:**

1. **Understanding the Glomerulus**: The glomerulus is a network of capillaries located in the kidney. It plays a crucial role in the filtration of blood.

2. **Filtration Process**: Blood enters the glomerulus under pressure. This pressure is essential for the filtration process to occur.

3. **Bowman's Capsule**: Surrounding the glomerulus is the Bowman's Capsule, which contains tiny pores known as filtration slits.

4. **Filtration Slits**: These filtration slits allow certain substances to pass through while preventing larger molecules from doing so.

5. **Components of Filtrate**: During the filtration process, water, urea, and other small dissolved materials pass through the filtration slits into the Bowman's Capsule.

6. **Ultrafiltration**: The selective process of filtering out smaller molecules while retaining larger molecules (like proteins) is referred to as ultrafiltration.

7. **Conclusion**: Therefore, the process that pushes out water and other dissolved materials from blood in the glomerulus is known as ultrafiltration.

**Final Answer**: The process that pushes out water and other dissolved materials from blood in the glomerulus is ultrafiltration.
