Week 11. The organs develop. First reflex acts. Your baby train to walk
Around this week, the child begins to generate its own red blood cells. In addition, it will begin to produce urine, the main component of amniotic fluid. Its skin is still transparent and its body is lengthening. Even so, its head is one third the length of the body. In the case of having a son, this week his testicles will begin to produce the male hormone known as testosterone. Now it will be about 6 centimetres and weigh 9 grams.
In these weeks the transformation is spectacular. There has been a metamorphosis, the embryo has increased 5 times in size, 200 cells have taken some positions and some muscles and nerves now move. The child now has liver, kidneys and a stomach the size of a grain of rice.
The fetus can already begin to develop one of its reflexes at week 11. It will begin to move its legs and will rebound and jump on the walls of the uterus. This is the patellar reflex, a biological resource that programs us to walk.
