The fetal period is the period during which tremendous growth occurs and the organs continue to develop and become functional. During this stage, the fetus gains weight rapidly, and its bodily proportions begin to resemble those of a newborn. The lungs continue to mature, and the fetus practices breathing movements. The brain also undergoes significant development, and the fetus begins to exhibit some basic reflexes. The fetal period typically lasts from the ninth week of pregnancy until birth.
