Question

Why are twins often born early?

1. The uterus becomes overdistended.
2. The placenta becomes distended.
3. The woman's body cannot tolerate the weight.
4. The fetuses become too large to deliver vaginally.

Answer 1

Twins are often born early due to the uterus becoming overdistended and the placenta becoming distended. However, not all twins are born prematurely. The correct answer is option 1 and 2.

Step-by-step explanation:

Twins are often born early due to multiple factors. One of the main reasons is that the uterus becomes overdistended, meaning it becomes stretched beyond its normal capacity. This can happen because of the presence of two fetuses instead of one.

When the uterus becomes overdistended, it can stimulate contractions and premature labor. Another reason is that the placenta can become distended. In twin pregnancies, there are often two placentas, which can put additional strain on the mother's body and contribute to preterm birth.

However, it is important to note that not all twins are born early. Some twins may be born at full term, while others may be born prematurely. Factors such as the mother's health, the position of the babies, and other medical conditions can also contribute to the timing of birth.
