11주와 12주 사이에는 태아 체중이 거의 60% 증가한다
12주면 임신의 첫 1/3 또는 1분기가 종료된다

이제 입 안이 뚜렷한 미뢰로 덮여있다
출생 때까지 미뢰는 혀와 입천장에만 남게 된다
See Snapshots
이르면 12주에 배변이 시작되고 약 6주 동안 계속된다
태아와 신생아의 결장에서 처음 배출되는 물질은 태변이라 불린다 이것은 소화관에서 생기는 소화효소, 단백질과 죽은 세포로 구성되어 있다

12주까지는 팔의 길이가 몸 크기에 비례해 최종적으로 균형 잡힌 길이에 도달한다 다리는 최종적으로 균형 잡힌 길이에 도달하는데 더 많은 시간이 걸린다

등과 머리 위를 제외하고 태아의 신체 전체 부분이 이제 가벼운 촉감에 반응한다
See Snapshots
성별이 좌우하는 발육상의 차이점들이 처음으로 나타난다 예를 들어 여아는 남아보다 턱 움직임을 더 자주 보인다
See Snapshots
앞서 보았던 움츠리는 반응과는 대조적으로 입 주위 부분에 자극이 오면 이제는 자극을 향하여 머리를 돌리고 입을 벌린다 이 반응은 '헤적이 반사'라 불리는데 출생 후에도 계속되며 신생아가 수유 때 엄마의 젖꼭지를 찾을 수 있도록 돕는 것이다

얼굴의 성숙은 볼에 지방이 붙고 치아가 발달하면서 계속된다
See Snapshots
15주까지는 혈액을 형성하는 줄기세포가 출현하고 골수에서 번식한다 혈액세포 형성의 대부분이 여기에서 발생한다
See Snapshots
6주 배아 때부터 움직임이 시작되지만 임산부는 14주에서 18주 사이에 태아의 움직임을 처음 느낀다 관례적으로 이 현상을 태동이라 부른다
