How feeds the fetus in the mother's womb?


Feeding the fetus

 The fetus is nourished in its mother’s womb by the placenta, which is an organ that develops in the mother’s womb during pregnancy, as it is the organ responsible for providing the nutrients and oxygen to the fetus, removing waste products from its blood, and the placenta attached to the wall of the uterus, and from which the umbilical cord arises,

You connect with the fetus. The placenta connects the fetus to the wall of the uterus, and it consists of the mother’s tissues (English: Maternal Tissues) and fetal tissues (English: embryonic tissues). It is found only in mammals and allows the mother to transfer large amounts of nutrients to the fetus for a long period of time before its birth.

The embryonic part of the placenta known as the chorion ( Chorion) is made up of trophoblast cells, which form a finger-like structure called the chorionic villi (Chorionic villi), and the placenta also includes the space between villi ( Intervillous space) that surrounds the placental villi and contains the mother’s blood. The mother’s blood flows from her blood circulation and passes through the 

space between the villi then returns again to her blood vessels. As for the fetus’s blood, it flows from the fetus towards the two main arteries in the umbilical cord ( Umbilical cord) Then, through the capillary network of the placental villi, and then back to the umbilical vein ( Umbilical vein). The fetus needs a lot of nutrients and oxygen, which he cannot get by himself, so the blood of the fetus 

flowing into the capillaries of the placental villi is poor in oxygen and nutrients, while the blood of the mother entering the placenta is rich in nutrients and oxygen, so the difference between the concentration of these substances Between the mother’s blood in the space between the villi and the fetus’s blood found in the placental villi, to their spread from the mother’s blood to the villi and from

 there to the fetus’s blood. In contrast, the fetus’s blood has high concentrations of carbon dioxide and other excreta, while the mother’s blood in the space has few concentrations of these substances, which leads to its spread from the blood of the fetus to the blood of the mother surrounding the villi through the chromosomes feeding the chorionic villi, to be removed by the various mother’s organs 

Like the lungs, liver, and kidneys with ease from her blood, it is worth noting that the mother's blood and the blood of the fetus cannot mix in the placenta; They are separated by the membranous endothelial cells of the fetus, and the nourishing tumor cells.

Suitable food during pregnancy

 The pregnant body during pregnancy needs more nutrients, vitamins, and minerals; Where you need to eat an additional amount of 350-500 calories daily during the second and third trimesters of 

pregnancy and a diet that lacks the important nutrients will negatively affect the growth and development of the fetus. Pregnant women must choose healthy foods rich in nutrients; To keep her

 fetus healthy and healthy, these include dairy products, legumes, eggs, salmon, sweet potatoes, broccoli, and green vegetables; Such as spinach, lean meat, cranberries, whole grains, dried fruits, and avocado, in addition to drinking enough water ranging from 1-2 liters per day.

Placenta

The placenta begins to grow and form since the fertilized egg attaches to the wall of the uterus, and the umbilical cord from it grows to the navel of the fetus, and it allows blood to flow from the mother to the fetus, and from the fetus to the mother, and the healthy placenta continues to grow throughout 

the pregnancy. The American Pregnancy Association estimates the weight of the placenta at 454-907g at birth, and it leaves the uterus during labor, 5-30 minutes after the fetus is released. The 

the placenta produces hormones related to pregnancy; Examples: chorionic gonadotropin (hCG), estrogen (English: estrogen), and progesterone (English: progesterone).

the umbilical cord

 The umbilical cord consists of three types of blood vessels, namely: two small arteries that transport blood from the placenta, and a large vein that restores blood to the fetus, and the umbilical cord can 

reach 60 cm in length, allowing the fetus to move without causing damage to the umbilical cord or placenta, and after Childbirth is cut, forming the remaining part of it after the baby's navel is healed. 

The umbilical cord may wrap around a part of the fetus during pregnancy, or it may form a knot and this is common and does not constitute a danger to the fetus, and each of the identical twins always 

has a secret cord for each of them, and a separate amniotic sac is usually separate, while they share the placenta Itself.

Amniotic fluid

 The amniotic fluid is a transparent, yellow-colored fluid that surrounds the fetus during pregnancy, and is located inside the amniotic sac, which allows the fetus to move within the womb, which helps 

the healthy growth of its bones, and also allows the lungs to grow properly, and it also helps To stabilize the temperature around the fetus, and to prevent heat loss, as it protects it from sudden 

external movements and shocks. The amniotic fluid is initially formed from the water that is produced by the mother, and in the period around the twentieth week of pregnancy this water is 

replaced by the urine of the fetus, and it includes substances Vitality; Like nutrients, hormones, and anti-inflammatory antibodies, it also helps protect the umbilical cord from stress, and reaches its highest level in approximately 36 weeks of pregnancy, reaching a volume of about one liter.
