Body Atlas Essay

Last meeting, we watched a film called body atlas. The film was about human body, bones, heart, blood, skin, reproductive system, and etc. It gives us a basic understanding of the parts and function of different systems in the human body. For example, the heart, it keeps our body alive because it pumps blood all around our body that contains oxygen. Heart has the main role of blood circulation in the body. Another important part of the body is the blood. It carries substances like nutrients such as amino acids and oxygen to the other parts of the body. It also contains white blood cells which are vital for the body’s immune system. From the film, one that strikes me the most was the reproductive system and how babies are made. We’ve all know the basic idea on how to make babies – man meets woman, they both get naked and have sex, and nine months later, a baby pop out. But from the film we’ve watched, it shows the step by step process on how the egg cell and sperm cell meet and how is the baby created inside the body. When a man ejaculates, despite the millions of sperms cell produced and released , only one can fertilized an egg.

If an egg cell meets up with a healthy sperm on its way to the uterus, the two can join and begin the process of creating a new life. The first 12 weeks of pregnancy, known as the first trimester, abound with changes and growth in the unborn baby. It takes up to two weeks for the process to be completed for you to become pregnant. In the 3rd week, sperm and egg come together to create a zygote. In the fifth week, though the unborn baby is less than 1/4-inch long, her brain, heart, spinal cord and other vital organs begin to form. The baby’s circulatory system also begins the first stages of development. Sixth and seventh week, Some of the baby’s basic facial features are now visible during the sixth and seventh weeks, and his heart begins pumping blood.

Eight week, with legs and arms growing longer and fingers beginning to develop, also develops an upper lip and nose, and the nipples and eyes are visible. Ninth and tenth week, Bones begin to form in your baby’s arms, which now bend at the elbows. The baby’s toes also start developing, and his eyelids and ears continue to be formed. At the 10th week, your baby’s head gets rounder, the neck begins to develop and the eyelids close to guard the eyes. At the 11th week, the baby ends the embryonic period and enters the fetus stage. The fetus begins to develop external genitalia. In the final week of the first trimester, the baby grows fingernails. After that, a new life begins.
