the urinary system of the fetus is developing at this stage; The fetus can swallow about a liter of amniotic fluid. It is excreted in the urine, and the immune system continues to grow 

and in the case of male fetuses, the testicle descends into the scrotum at this stage, and the rate of weight gain increases due to increased fat storage. 

The fatty layer of the skin plays an important role in regulating the body temperature of the fetus after birth, of course, as it increases in children enjoying a good condition, 

and this fatty layer is called the adipose layer or the fetus, and it also helps prevent water loss in the fetus and strengthen its immunity.

the fetus's legs are directed towards the chest most of the time, and the fetus's position may change so that the movement of the fetus can be felt, and you can even see some signs of its movement. in the abdomen. 

The level of amniotic fluid decreases with the progression of pregnancy, and the volume is estimated at about a quarter of a liter at this stage. 

The amniotic fluid continues to decrease until delivery, and most of the organs are fully grown and developed during this week; The liver can process some waste, and the kidneys are fully developed and ready to function,  although the fetus may appear to be fully developed at this stage,

many important processes continue to develop and grow; During the last five weeks of pregnancy, the weight of the fetus's brain increases by about a third, except for the skin due to the increase in subcutaneous fat mass, and wrinkles disappear.
