Question

Fetal heart starts contracting at

• A. 10-12 days
• B. 10-12 weeks
• C. 3-5 weeks
• D. 3- 5 month

Answer 1

The Correct Option is C

During embryonic development, the fetal heart is one of the first organs to form and become functional. The heart begins its initial contractions, or heartbeat, during the early weeks of gestation. Typically, the fetal heart starts contracting at approximately 3 to 5 weeks of gestation. This early cardiac activity is critical for the circulation of nutrients and waste products in the developing embryo. Therefore, considering the options provided:

• 3-5 weeks: This is the correct time frame when the fetal heart starts contracting.
• 10-12 days: This is too early for the fetal heart contractions.
• 10-12 weeks: By this time, the heart has already been beating for several weeks.
• 3-5 months: This is significantly later than when the first contractions occur.

Thus, the correct answer is 3-5 weeks.
