Developing Fetus at Verious Stages of Pregnancy

From the first moment the cells begin to divide and create an embryo, fetal development and the stages of pregnancy progress in a longtime sequence. When the egg is fertilized, a zygote develops. In this first stage, which happens in the first 2 weeks of the pregnancy, the cells multiply and develop. The next phase of fetal development and the stages of pregnancy occurs when the zygote becomes an embryo. During week three, the embryo starts to develop the buds that will become the arms and legs of the fetus. The digestive system also has basic beginnings at this time. 

By the 5th week of fetal development and the stages of pregnancy, the facial features have started to form. The embryo has begun to produce hormones and the presence of these hormones stop the mum’s menstrual cycle. When the embryo becomes about an in. 

long, about the sixth week of the fetal development and the stages of pregnancy, the brain has begun to develop its component parts; facial features, toes and fingers are noticeable and a heartbeat can be detected in an ultrasound test. During the n ext many weeks, the organs continue to develop and the features become more discernible. The genitalia form, though they can not be distinguished at this stage in an ultrasound. Bones are beginning to form and the muscles can contract. By the end of the 1st trimester, the fetus is roughly 3 inches in length and weighs only about an oz.. In the second trimester of fetal development and the stages of pregnancy, the fetus continues to develop the characteristics that make it recognizable as a human baby. Development has progressed to the point that the fetus will begin to move a touch ; it is in this time a mummy will start to feel movement. As this period progresses, the fetus will develop waking and sleeping cycles the mum will shortly be ready to detect and recognize. At roughly the 24th week, a usually developed fetus is about 12 inches long and weighs about two pounds. It might be able to survive, with assistance from current medical technology, if it were delivered. During the last weeks of fetal development and the stages of pregnancy, or the third trimester, the bones are developed, though they are still pliable. The fetus can breathe, exhale, and even cry. The eyelids open and the lungs continue to develop until the moment of birth. The fetus gains in size and moves less because there is less room to maneuver. Most of the movement occurs as the fetus shifts its position in preparation for birth. At the age of 30 weeks, the fetus would be tiny and considered early, but it could be capable of living on its own if it were delivered. The fetus is regarded entirely developed at the age of 38 weeks and would be completely capable of living on its own if delivered, though the ordinary delivery date is thought to be at the end of the 40th week.
