Development for The Three Trimesters
The third trimester
the fetus continues to grow at a rapid rate.
fat accumulates under the skin to provide insulation for the fetus once it is born.
protein intake by the mother is important during this time because protein is essential for the rapid amount of brain growth that occurs.
the fetus now might respond to sounds in the environment, such as music or the sound of its mother’s voice.

The second trimester
during the 18th and 20th week, the fetal heartbeat can be heard by a stethoscope.
The embryo is capable of sucking its thumb and developing hiccups.The mother may feel light kicks or fluttering sensation.
When the embryo's hair forms, it can open its eyes.
The fetus may be able to survive out of the mother's uterus, with the aid of medical intervention.but it can't maintain a constant body temperature,so the developing fetus has high chances of dying.
respiratory failure may accuse since the embryo's lungs aren't fully developed.
Even its immune system is very weak so the embryo can be ill.

The first trimester
-In the first trimester, all tissues, organs, and organ systems begin to develop
-During this time of development, the embryo is especially vulnerable to the effects of alcohol, tobacco, drugs, and other environmental influences, such as environmental pollutants.
-During the first two weeks of development, the mother might not realize that she is pregnant because she has not yet missed a menstrual period.
-A lack of certain essential nutrients during this time might cause irreversible damage to the developing embryo.
-At the end of eight weeks, the embryo is called a fetus. All of the organ systems have begun to form.
-By the end of the first trimester, the fetus can move its arms, fingers, and toes and make facial expressions. Fingerprints also are present.
