Fetal growth characteristics
The four-dimensional color ultrasound image of the fetus at five months of pregnancy shows that the fetus is about 16-18 centimeters long and weighs about 250 grams. At this time, various data such as the fetus\’ head circumference, chest circumference, and abdominal circumference are gradually increasing. The fetus\’s abdomen is already filled with amniotic fluid, which provides sufficient conditions for its later growth. In addition, the fetus\’s limbs gradually become more flexible, the fingers and toes have formed, and the length of the limbs gradually becomes similar to the head and torso.
On the placenta of a five-month-old fetus, the subcutaneous tissue gradually thickens, and fat deposition also gradually increases. The placenta is one of the important organs of the fetus. It can provide nutrients and oxygen to the fetus and can also metabolize waste products produced by the fetus.
Organ system development
In a five-month-old fetus, each organ system has been basically formed, and its nervous, cardiovascular, digestive, respiratory, urinary and other systems are responsible for their own functions. Especially the heart, which has completed differentiation and tissue formation, beats steadily and delivers oxygen and nutrients to the whole body.
In addition, the respiratory system of the five-month-old fetus also begins to function gradually. As an embryo, a child inhales fluids like amniotic fluid, but by five months, the fetus begins to take in oxygen and expel carbon dioxide through the lungs and placenta.
Fetal gender
Through four-dimensional color ultrasound technology, it is now possible to clearly identify the gender of the fetus. At five months, the gender characteristics of male and female fetuses are already very obvious. The female fetus\’s genitals have completed formation, and the male fetus\’s gonads have begun to produce testosterone.
Notes
During the fifth month of pregnancy, pregnant women should pay special attention to some health care measures. For example, women should avoid strenuous exercise, get enough rest, and ensure adequate nutritional supply. In addition, pregnant women should also avoid contact with pollutants and viruses, especially foods that are easy to carry germs, such as raw fish, raw meat, and semi-raw foods.
Overall, five-month-old fetuses already exhibit human-like features. Its various organ systems have been formed, and they have begun to have their own functions. For pregnant women, good lifestyle and eating habits should be maintained at this time to provide adequate nutrients and growth conditions for the fetus.
