Filtration slits are formed by

Options

A. endothelium of glomerular capillaries
B. podocytes of glomerular capillaries
C. podocytes of Bowman's capsule
D. podocytes of renal capsule

Answer

**Step-by-Step Solution:**

1. **Understanding Filtration Slits**: Filtration slits are small spaces that allow certain substances to pass from the blood into the nephron during the filtration process in the kidneys. They are crucial for the formation of renal filtrate, which includes water, glucose, amino acids, and other nutrients.

2. **Identifying the Components**: The filtration slits are formed by specialized cells called podocytes. These cells are located in the lining of Bowman's capsule, which is part of the nephron.

3. **Role of Podocytes**: Podocytes have foot-like extensions known as pedicels. These pedicels interdigitate with each other, creating the filtration slits between them.

4. **Location of Podocytes**: Podocytes are found in Bowman's capsule, which surrounds the glomerulus (a network of capillaries). The glomerulus is responsible for filtering blood.

5. **Conclusion**: Given the options provided in the question, the correct answer is that filtration slits are formed by the podocytes of Bowman's capsule.

**Final Answer**: Filtration slits are formed by the podocytes of Bowman's capsule.
