Detailed explanation of fetal size and development in three months of pregnancy
In the third month of pregnancy, the fetus has basically formed and begun to take on its real appearance. The fetus is about 5 centimeters from head to toe and weighs 12 grams. The following is a detailed explanation from four aspects.
Appearance features
In the third month of pregnancy, the appearance of the fetus has begun to show obvious differences. At this time, the head is still very large, accounting for more than half of the entire body length, but the neck has formed and the boundary between the head and neck is more obvious. On the head, facial features have begun to appear, including eyes, ears, and mouth and nose. The limbs are also obvious, and the fingers and toes have been separated, but they are still short and thin. At this time, the fetus has no subcutaneous fat layer, the skin is very thin, and the blood vessel network is also obvious.
Organ system development
By the third month of pregnancy, all organ systems of the fetus have been formed, but they still need further development and improvement. At this time, the fetal liver has produced red blood cells, the kidneys can perform excretory functions, the gastrointestinal tract has developed, and the fetus can swallow amniotic fluid autonomously. The four atria and ventricles of the fetal heart have also formed, begun to beat regularly, and have a relatively complete blood circulation system.
Athletic ability and behavioral performance
Beginning in the third month of pregnancy, the fetus\’s ability to move begins to gradually increase. The fetus\’s limbs begin to move and its head can also make turning movements. At this time, the fetus\’s auditory system has also been fully developed, able to hear external sounds, and will show obvious reactions when hearing sounds. In addition, the fetus also begins to have a clear distinction between sleeping and waking states.
Nutritional and health needs
During the third trimester of pregnancy, the fetus’s nutritional needs are already increasing. The fetus\’s brain begins to develop rapidly at this time, so the mother should focus on providing adequate nutrition, especially foods rich in protein and Omega-3 fatty acids. In addition, it is also very important for future mothers to take care of themselves during pregnancy, including maintaining a healthy lifestyle, avoiding exposure to dangerous environments, and avoiding overwork and stress.
In short, during the third trimester, the fetus has made great progress. As a future mother, you must pay attention to nutrition and health care during pregnancy and provide adequate nutrition to ensure the health and growth of the fetus.
