The fetus remains in its mother’s womb for a period of up to 9 months, but how does the fetus nourish in the mother’s womb?? Here is the answer to this article.
How does the fetus feed in the mother’s womb?
The nourishment of the fetus in the womb of its mother is necessary for its proper growth and maintenance of its health in the long term, but how is the fetus nourished in the womb of the mother? This is what we will learn in the next article.
How does the fetus feed in the mother’s womb?
The following is an explanation of the question: How is the fetus nourished in the mother’s womb? By steps:
Nutrients and oxygen pass to the baby’s liver through the umbilical vein after passing through the placenta.
Most of the oxygen-rich blood travels to the inferior vena cava.
The blood then enters the heart through the right atrium, most of it enters the left atrium and moves to the left ventricle to be pumped into the ascending aorta, and through the ascending aorta, the blood travels to the brain, heart, and lower parts of the body.
The blood carries carbon dioxide and a group of other wastes when it returns to the heart, enters the right atrium and then the right ventricle bypasses the lungs to the descending aorta connected to the umbilical arteries.
The blood then flows to the placenta and back into the maternal circulation for nutrients and oxygen to be exchanged again.
The anatomical structure of the placenta that helps nourish the fetus
After knowing how the fetus is nourished in the mother’s womb? We have to know the physiological structure that connects the mother to the fetus, as the anatomical structure of the placenta prevents direct communication between the mother’s blood and the fetus’s blood.
In fact, the transit of nutrients and oxygen is complicated, as the placenta contains two layers of villi through which nutrients and oxygen must pass, which are as follows:
-
Syncytiotrophoblasts
It is the outer layer of the placenta that forms the epithelial tissue, and it has two polarized membranes, one facing the maternal blood circulation, and the other facing the fetal capillaries.
-
Fetal capillary epithelium
It is a selectively permeable membrane, which passes small particles, such as: amino acids and glucose, and blocks the passage of larger ones.
The effect of the mother’s diet on the fetus and the most important tips
The unbalanced and unhealthy diet of the mother affects the transport of food across the placenta, which affects the health of the baby.
Therefore, you must follow a healthy diet, and consult a specialist doctor about the appropriate food during pregnancy, in addition to the importance of following the following tips:
Iron intake is necessary to prevent anemia by eating red meat and spinach.
Take a folic acid supplement before and during pregnancy, especially in the first 28 days. Folic acid protects the fetus from developing neural tube defects.
Increase calcium consumption, as the growing child’s calcium requirements are high, and it can be obtained mainly from dairy products or calcium supplements in case of lactose intolerance.
Eating proteins necessary for fetal growth and blood production.
Avoid caffeine to reduce the risk of miscarriage.
Do not consume unpasteurized milk products and juices.
Refrain from eating uncooked eggs or any food that contains undercooked eggs or undercooked meat.
Avoid eating processed meat, such as sausage.
Avoid eating high-mercury fish, such as swordfish and tuna.
