~~Fetal Development~~
Development of the Embryo and Fetus

Overview

* Did You Know?
Pregnancy is counted from the first day of the mother's last period. This means that at conception, the unborn child is already considered two weeks old.1
First Trimester

Week 2* Conception is the moment at which the sperm penetrates the ovum. Once fertilized it is called a zygote, until it reaches the uterus 3-4 days later.

Week 4 The embryo may float freely in the uterus for about 48 hours before implanting. Upon implantation, complex connections between the mother and embryo develop to form the placenta.
Week 6 The embryo is about 1/5 of an inch in length. A primitive heart is beating. Head, mouth, liver, and intestines begin to take shape.
Week 10 The embryo is now about 1 inch in length. Facial features, limbs, hands feet fingers and toes become apparent. The nervous system is responsive and many of the internal organs begin to function.
Second Trimester

Week 14 The fetus is now 3 inches long and weighs almost an ounce. The muscles begin to develop and sex organs form. Eyelids, fingernails, and toenails also form. The child's spontaneous movements can be observed.

Week 18 The fetus is now about 5 inches long. The child blinks, grasps, and moves her mouth. Hair grows on the head and body.
Week 22 The fetus now weighs approximately 1/2 a pound and spans about 10 inches from head to toe. Sweat glands develop, and the external skin has turned from transparent to opaque.
Third Trimester

Week 26 The fetus can now inhale, exhale and even cry. Eyes have completely formed, and the tongue has developed taste buds. Under intensive medical care the fetus has a over a 50% chance of surviving outside the womb.

Week 30 The fetus is usually capable of living outside the womb and would be considered premature at birth.
Week 40 This marks the end of the normal gestational period. The child is now ready to live in outside of his mother's womb.

Basically the female body produces what is known as the egg cell, and the male produces the sperm cell. When a male and female have intercourse, and the male orgasms within the female, he ejaculates millions of sperms cells, that swim up the female reproductive system until one sperm cell meets the egg cell. When the sperm cell reaches the egg cell it enters it and hence the egg cell becomes fertile. Over the next 9 months, the first two cells start to grow and multiple in twos, so from 2 cells you get 4, from 4 you get 8 and from 8 you get 16 etc, until the fetus is form. When the baby is ready to be born it turns head down so that it can leave the female body.

They need to do away with insane mothers who kill their babies, because these babies can't fight back.

It was on the news this morning. A mother in Arkansas has killed her three kids. They are taking the three babies back to New York to lay them to rest. My prayers are with the father who lost his children; I am truly sorry for your loss.
