(b) : The human pregnancy lasts 9 months. In human beings, the embryo's heart is formed after one month of pregnancy. The first sign of growing fetus is observed by listening to the heart sound carefully through the stethoscope. The fetus develops limbs and digits by the end of the second month of pregnancy. Most of the major organ systems are formed by the end of 12 weeks i.e., first trimester, for example, the limbs and external genital organs are well developed. The first movements of the fetus and appearance of hair on the head are usually seen during the fifth month. The body is covered with fine hair, eye-lids separate, and eyelashes are formed by the end of about 24 weeks, i.e., end of second trimester. The fetus is fully developed and is ready for the delivery by the end of nine months of pregnancy.
