Answer

**Step-by-Step Text Solution:**

1. **Understanding Abortion**: Abortion is defined as the termination of a pregnancy, which can occur naturally or be induced through medical or surgical means. It results in the expulsion of the fetus from the uterus.

2. **Stages of Pregnancy**: Pregnancy is divided into three trimesters:
- **First Trimester**: Weeks 1 to 12
- **Second Trimester**: Weeks 13 to 26
- **Third Trimester**: Weeks 27 to 40

3. **Risk Factors in the First Trimester**: During the first trimester, the risk of abortion is relatively high. This is because the embryo is not yet fully developed and is not firmly attached to the uterine lining. The chances of miscarriage or abortion are more prevalent during this period.

4. **Risk Factors in the Second Trimester**: As pregnancy progresses into the second trimester, the fetus becomes more securely attached to the mother’s tissues. However, complications can still arise, leading to a higher risk of abortion during this stage as well. The fetus is now more integrated into the mother's biological systems, which can introduce additional risks.

5. **Conclusion**: The maximum risk of abortion occurs during the first trimester due to the incomplete attachment of the embryo. However, significant risks also exist in the second trimester due to the intimate connection between the fetus and maternal tissues.

**Final Answer**: Abortions are much riskier during the first trimester, but risks remain significant in the second trimester as well.
