Body Systems Development
Heart and Circulation
The baby’s heart is fully formed and beating consistently, pumping oxygen and nutrients throughout the tiny body. Major arteries and veins are well-developed, supporting circulation.

Bones are hardening and growing stronger, while muscles are developing, allowing for increased movement and coordination. Fingers and toes are fully formed and can be seen kicking and grasping.
