During month 1, when does the heart begin to pump?

Explanation:
The key idea is that the heart begins working very early in development. By around week 6 of gestation, which in this course’s month-1 timeline corresponds to the end of the first month, the heart has formed and starts pumping blood to establish circulation for the growing embryo. This early heartbeat is a fundamental milestone that happens well before birth. Week 2 is too early for a pumping heart, and Week 12 or birth occur much later in development, after the heart has already begun beating.
