(c) process by which urine is concentrated
C. (3) (d) presence of glucose in urine
(b) can cause dilation of blood vessels
D. (4) (a) accumulation of uric acid in blood
(d)presence of glucose in urine

Answer

To solve the question regarding the terms uremia, ANF, micturition, and glycosuria, we will analyze each term and its correct explanation step by step.

### Step-by-Step Solution:

1. **Understanding Uremia**:
- Uremia is a medical condition characterized by the accumulation of waste products, particularly urea, in the blood due to impaired kidney function. When the kidneys are damaged, they cannot effectively filter out waste, leading to high levels of urea and other toxins in the bloodstream.
- **Hint**: Remember that uremia is related to kidney dysfunction and waste accumulation.

2. **Understanding ANF (Atrial Natriuretic Factor)**:
- ANF is a peptide hormone produced by the heart's atria. Its primary function is to promote the dilation of blood vessels and to help regulate blood pressure by promoting sodium excretion in the urine.
- **Hint**: ANF is associated with the heart and plays a role in blood pressure regulation.

3. **Understanding Micturition**:
- Micturition refers to the process of urination, specifically the involuntary action of expelling urine from the bladder. This process is controlled by the nervous system and involves the relaxation of the bladder sphincters.
- **Hint**: Micturition is synonymous with urination and involves the release of urine.

4. **Understanding Glycosuria**:
- Glycosuria is the condition where excess glucose is present in the urine. This typically occurs when blood glucose levels are elevated, such as in diabetes mellitus, where the kidneys cannot reabsorb all the glucose filtered from the blood.
- **Hint**: Glycosuria is linked to diabetes and the presence of glucose in urine.

### Conclusion:
After analyzing each term, we can summarize the correct explanations:
- **(a) Uremia**: Accumulation of urea in the blood due to kidney failure.
- **(b) ANF**: A hormone released from the heart that causes dilation of blood vessels.
- **(c) Micturition**: The involuntary process of releasing urine.
- **(d) Glycosuria**: Presence of excess glucose in urine, commonly seen in diabetes.

### Final Answer:
The correct option is the one that accurately describes:
- A: Accumulation of urea in blood (correct)
- B: ANF as a release from the atria of the heart (correct)
- C: Micturition as the process of urination (correct)
- D: Glycosuria as the presence of glucose in urine (correct)

Thus, the correct answer is **Option 3**.
