Explanation:
The heart is the organ that is formed after one month of pregnancy. and the first sign of a developing fetus is the sound of the heartbeat. The end of the second month marks the development of the limbs and digits. The second trimester or after 12 weeks the major organ systems such as the limbs, external genitalia are formed. The second trimester or the end of 24 weeks is characterized by the development of the hair,eye-lids
