Statement-1: The uriniary bladder dilates a good deal as urine trickles into it from the ureters.
Statement-2: Urinary bladder is lined throughout by transitional epithelium

Options

A. both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect
C. Statement 1 is incorrect but statement 2 is correct
D. Both statements 1 and 2 are incorrect.

Explanation

To analyze the given statements, let's break them down step by step:

### Step 1: Understanding Statement 1
- **Statement 1**: "The urinary bladder dilates a good deal as urine trickles into it from the ureters."
- The urinary bladder is a muscular sac that stores urine. As urine flows from the ureters into the bladder, the bladder expands to accommodate the increasing volume of urine. This dilation is a normal physiological response to the filling of the bladder.

### Step 2: Understanding Statement 2
- **Statement 2**: "Urinary bladder is lined throughout by transitional epithelium."
- The urinary bladder is indeed lined by transitional epithelium, which is a specialized type of epithelium that can stretch and accommodate the bladder's expansion as it fills with urine. This epithelium allows the bladder to expand and contract without losing its integrity.

### Step 3: Conclusion
- Both statements are true:
- Statement 1 is correct because the urinary bladder does dilate as it fills with urine.
- Statement 2 is correct because the lining of the urinary bladder is made up of transitional epithelium.

### Final Answer
Both Statement 1 and Statement 2 are correct.
