Human uterus is

Options

A. paired with well separated oviduct
B. single large chamber with posterior part of oviduct fused to it anteriorly
C. paired with partially fused oviducts
D. a single large chamber with completely fused oviducts

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of the Uterus**:
- The human uterus is a single, hollow, muscular organ located in the female reproductive system. It is not paired; rather, it exists as one structure.

2. **Identifying Components**:
- The uterus has a cavity known as the uterine cavity.
- The lower part of the uterus is called the cervix, which connects to the vagina.
- On either side of the uterus are the fallopian tubes (oviducts) and ovaries.

3. **Function of the Uterus**:
- The primary function of the uterus is to provide a suitable environment for the implantation of a fertilized egg and to support the development of the fetus during pregnancy.

4. **Analyzing Options**:
- The first option states that the uterus is paired with well-separated oviducts. This is incorrect because the uterus is a single structure.
- The second option describes the uterus as a single large chamber with the posterior part of the oviduct fused to it. This is correct, as the oviduct connects to the uterus.
- The third option suggests a paired uterus with partially fused oviducts, which is also incorrect.
- The fourth option states a single layer of chamber with completely fused oviducts. This is incorrect because the oviducts are not completely fused; they connect to the ovaries.

5. **Conclusion**:
- The correct description of the human uterus is that it is a single large chamber with the posterior part of the oviduct fused to it.

### Final Answer:
The human uterus is a single large chamber with the posterior part of the oviduct fused to it.
