Study the following statements about excretory system in humans.
1. Wastes dissolved in water are filtered out as urine in the kidneys.
Urine stored in urinary bladder is passed out through the urinary opening at the end of the urethra.
3. Ureter carries urine to the urinary bladder.
4. Useful substances are absorbed back in the blood.
5. Blood containing useful and harmful substances reaches the kidney for filteration.
The correct order of the processes given in the above statements is

Options

A. 2, 4, 5, 1, 3
B. 5, 4, 1, 2, 3
C. 4, 5, 1, 3, 2
D. 5, 4, 1, 3, 2

Explanation

To solve the question regarding the correct order of processes in the human excretory system based on the provided statements, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Processes**:
- The first step is to understand what each statement describes about the excretory system.
- Statement 1: Wastes dissolved in water are filtered out as urine in the kidneys.
- Statement 2: Urine stored in the urinary bladder is passed out through the urinary opening at the end of the urethra.
- Statement 3: Ureter carries urine to the urinary bladder.
- Statement 4: Useful substances are absorbed back in the blood.
- Statement 5: Blood containing useful and harmful substances reaches the kidney for filtration.

2. **Determine the Sequence of Events**:
- **Step 5**: Blood containing useful and harmful substances reaches the kidney for filtration. (This is the first step in the process.)
- **Step 4**: Useful substances are absorbed back in the blood after filtration. (This follows the filtration process.)
- **Step 1**: Wastes dissolved in water are filtered out as urine in the kidneys. (This occurs after the blood is filtered.)
- **Step 3**: Ureter carries urine to the urinary bladder. (After urine is formed, it is transported to the bladder.)
- **Step 2**: Urine stored in the urinary bladder is passed out through the urinary opening at the end of the urethra. (Finally, urine is excreted from the body.)

3. **Compile the Correct Order**:
- The correct order of the statements based on the sequence of processes is: 5 → 4 → 1 → 3 → 2.
- This corresponds to option D, which is 54132.

### Final Answer:
The correct order of the processes given in the statements is **54132** (Option D).
