In Frog, ureters open in

Options

A. Rectum
B. Urinary bladder
C. Colon
D. Cloaca

Answer

**Step-by-Step Solution:**

1. **Understanding the Anatomy of the Frog:**
- The frog has a unique excretory system that includes kidneys, ureters, and a cloaca. The kidneys filter waste from the blood and produce urine.

2. **Identifying the Ureters:**
- Each kidney in a frog has a fine duct known as the ureter. The ureters transport urine from the kidneys to another structure.

3. **Exploring the Options:**
- The question provides four options regarding where the ureters open:
- A) Rectum
- B) Urinary Bladder
- C) Colon
- D) Cloaca

4. **Analyzing Each Option:**
- **Rectum:** The rectum is part of the digestive system and is not where the ureters open. Therefore, this option is incorrect.
- **Urinary Bladder:** While the urinary bladder stores urine, the ureters do not open directly into it. This option is also incorrect.
- **Colon:** The colon is part of the large intestine and is not the opening for the ureters. Thus, this option is incorrect as well.
- **Cloaca:** The cloaca is the common chamber where the urinary, reproductive, and digestive tracts converge. In frogs, the ureters open into the cloaca. This option is correct.

5. **Conclusion:**
- The correct answer to the question "In Frog, ureters open in" is **Cloaca** (Option D).
