Human Development (Conception-Birth)

Satisfactory Essays
Human development can be described as the way a human body forms as the process of life begins. Along this process different kinds of mutations and diseases can occur, some may be natural and others self-afflicted (Sigelman & Rider). The area of human development I am focusing on is the time between conception and birth of a fetus, this is especially important because it is the making of a life (Sigelman & Rider). This time frame of nine months is called gestation. It is divided into three equal trimesters (Holt, Rinehart & Winston) This period of one’s life span occurs the fastest and has one of the most important environments (Sigelman & Rider).
Throughout the life of an embryo/fetus before it is born as a grown baby, there are several stages that their bodies have to go through. Cells that are formed earlier and have not been specialized yet can be identify as stem cells. When the spiral cord begins to form the embryo is coming into three weeks of growth and begins to have a system to support its body (Sigelman & Rider). This time is very vulnerable for the development of the baby’s organs (Holt, Rinehart & Winston). Five to six weeks the torso, head, and limbs and begun to form. Also the system that takes shape to transport nutrients known as the umbilical cord has formed to the body. A tiny heart is now beginning to pump blood and have a beat (Sigelman & Rider). Coming up to seven and eight weeks, the organs of the embryo have started to function and the embryo is now called a fetus (Miller & Levine). The time after the ninth week to the birth of the child is referred to as the fetal period. During the fourth, fifth, and sixth month the features of the body start to form and become more complex and specialized which gives ...

...reater respect for the amazing process of development. I never realized how much it took and how much had to go right for a baby to be born.
