(iv) In uremic patients urea and glucose can be removed by a process called hemodialysis

Options

A. I,ii,iii
B. I,ii,iv
C. I only
D. I,ii,iv

Answer

To determine which statements are not incorrect, we will analyze each statement one by one:

1. **Statement (i)**: "Liver, the largest gland in our body secretes cholesterol, degrade steroid hormones, vitamins and drugs."
- **Analysis**: This statement is true. The liver is indeed the largest gland in the human body and plays a crucial role in metabolizing and secreting cholesterol, degrading steroid hormones, and processing vitamins and drugs.

2. **Statement (ii)**: "Sebaceous glands eliminate certain substances like urea, sterols and sebum."
- **Analysis**: This statement is also true. Sebaceous glands do produce sebum, which contains various substances including sterols, and they can eliminate some waste products, although urea is not their primary function.

3. **Statement (iii)**: "Sweat produced by sweat glands in an oily fluid containing NaCl."
- **Analysis**: This statement is false. Sweat produced by sweat glands is primarily a watery fluid, not oily. It does contain NaCl (sodium chloride), but the description as "oily" is incorrect.

4. **Statement (iv)**: "In uremic patients urea and glucose can be removed by a process called hemodialysis."
- **Analysis**: This statement is true. Hemodialysis is a medical procedure that removes waste products, including urea, from the blood of patients with kidney failure. In diabetic patients, glucose can also be present and can be removed during this process.

Based on the analysis:
- Statements (i), (ii), and (iv) are true (not incorrect).
- Statement (iii) is false (incorrect).

**Conclusion**: The statements that are not incorrect are (i), (ii), and (iv).

**Final Answer**: The correct statements are (i), (ii), and (iv).
