6 weeks
This Lab project is on the developement stages of pregnancy.
1) Fertilization: Is the most important part of fetal development. It happens when a sperm finally reaches an egg. It’s what makes everything else possible. This happens on day one. Or two weeks into a woman’s cycle.
2) Implantation occurs somewhere between 7-12 days after fertilization. The egg must be attached to the mother’s womb in order to grow and survive.
3) Placenta formation occurs at about 13 days. This is very important because the placenta provides blood and nourishment to the fetus.
4) At 23-25 days the heart is forming and starting to beat. Again the human heart is vital.
5) At 31-35 days the heart is forming the 4 chambers and limbs are present. These limbs will eventually turn it arms and legs. Arms and legs are essential to our lifestyle.
6) 42-44 days and the teeth buds begin to form. Ears are also recognizable at this stage. Our senses are important.
7) 44-48 days and the kidneys start to produce urine. We need vital organs to survive.
8) Fingers and toes are present at 53-54 days.
9) 54-56 days the penis and clitoris are forming. This is important to be able to continue the circle of life.
10)At 61-68 days the brain structure is complete and the brain will grow larger. The brain is obviously a huge mile stone.
11)At 12 weeks the babies genitals are fully visible. The baby starts moving around.
12)The fetus is able to hear at 22 weeks.
13)At 26 weeks the lungs are able to breathe oxygen and the eyes have lashes. Lung development is critical.
14)At 32 weeks the baby is almost 4 lbs. It can open its own eyes when awake or close them when sleeping.
15)At forty weeks the baby is ready to be born.
