Detailed pictures of fetal development at 9 weeks of pregnancy
In the 9th week of pregnancy, the fetus has begun to obtain various nutrients and oxygen from the mother\’s body, and the development of body organs and tissues is gradually improving. The following will introduce in detail the development of the fetus at 9 weeks of pregnancy in four aspects.
Appearance characteristics
At 9 weeks of pregnancy, the fetus is only about 2.5 centimeters long and weighs about 2 grams. At this time, the fetus\’s head is still very large compared to its body, occupying more than half of the entire body. The positions of the eyes and ears have also been basically determined, but there are still no specific outlines. In addition, the fetus\’s limbs will gradually become longer.
Nervous system and internal organs
At 9 weeks of pregnancy, the fetus\’s nervous system begins to further develop, and the early structures of the brain and spinal cord have also been formed. In addition, the fetus\’s internal organs such as heart, liver, and kidneys also begin to function. Although the fetal body is still very tiny, growth and functional development of all systems and organs progresses step by step.
Physiological functions
At 9 weeks of pregnancy, the fetus can already digest nutrients provided by the mother through phagocytosis. In addition, the fetus can try to breathe in the amniotic fluid at this time, which is very beneficial to the normal development of the lungs and respiratory system.
Other features
At 9 weeks of pregnancy, the fetus\’s reproductive system has begun to form, and the differences between men and women have begun to become obvious. By this time, unique features such as the fetus\’s fingerprints and foot prints have also been formed. In addition, the fetus will gradually become active at this time, and the mother will feel some slight movements.
To sum up, at 9 weeks of pregnancy, all aspects of fetal development have begun to take shape, but there are still many aspects that need further improvement. In the coming weeks, the fetus\’s different systems and organs will further mature, laying the foundation for them to spend a good period of development in the mother\’s body.
