Question

TASK: Describe and explain the many stages involved in the development of a human embryo and fetus, as well as the

need for proper pregnancy care, nutrition, and overall healthy choices during pregnancy.

Answer 1

It’s always important to eat a balanced diet — and it’s even more important when you’re pregnant because what you eat is the main source of nutrients for your baby. However, many women don’t get enough iron, folate, calcium, vitamin D, or protein. So when you are pregnant, it is important for you to increase the amounts of foods you eat with these nutrients.

Most women can meet their increased needs with a healthy diet that includes plenty of fruits, vegetables, whole grains, and proteins, you should try to eat a variety of foods from these basic food groups. If you do, you are likely to get all the nutrients you need for a healthy pregnancy.

Answer 2

The very first stage of the development is the fertilization of an egg .It takes about 24 hours for a sperm cell to fertilize an egg. When the sperm punctures the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete. The second stage is the two cells; this stage occurs approximately 30 hours after fertilization and results in a 2-cell embryo. The next stage is the 4 cell embryo is the result of a second cleavage event and occurs at approximately 40 hours after fertilization. The individual cells are called blastomeres. At this stage the process of embryonic genome activation is started in human embryos. Next is the 8 cell stage actually consisting of 6-12 cells develops by day 3 of human embryonic development now there is now an morula or early-stage embryo consisting of 16 cells (called blastomeres) in a solid ball contained within the zona pellucida . 5 to 6 days there is a blastocyst or embryo that will develop into a baby .The fourth week ball of cells is splitting into the embryo and placenta .The neural tube the building block of the spine brain and backbone is already formed.The amniotic sac and fluid are forming. This would be a good time for the mother to get good exercise as well as to stop drinking and smoking .The mother should also see a doctor and start taking prenatals. This is important because it helps with the development and growth of the baby . The next stage is 10 weeks. The baby is as big as a strawberry. At stage 16 the baby is the size of an avocado. 16 weeks of pregnancy the mother may notice an increase in energy .Sleep is important because lack of sleep can result in growth problems in the unborn baby. 20 weeks the baby is nearly formed this is the second trimester the mother should avoid raw meat,eggs,and fish. By 24 weeks your baby's organs are fully developed .
