To commence with, during development a human being grows at an astonishingly rapid pace. According to Guttmacher Institute, “89% of all abortions in the United States are performed in the first trimester of pregnancy.” (2005). In the first trimester (16 weeks), the baby’s eyes and eyelids, nose, mouth, and tongue have formed, and the baby's reproductive organs also develop. The cardiovascular system is the first system that begins to function. The baby’s heart begins to circulate their own blood, similar to his mother’s heart, twenty-two days after conception. Electrical brain activity can be detected at six or seven

When the brain is developing it is creating neurons, which are specialized cell transmitting nerve impulses, a nerve cell. Just a small piece of the brain contains thousands of nerve cells within it. Neurons never reproduce themselves and are very rarely replaced by others. The brain cells form quite rapidly roughly just four weeks into the process. When the fetus is growing the neurons make their way out of the neutral cube to build the brain layer upon layer. The brain builds connections very rapidly nearly a couple million every second and it begins to wire itself by following a genetic blue print. Neurons travel in waves, millions each day, which scientists like to call migration. After twenty-four weeks the vital organs of the body are formed, for example, the heart begins to beat on

Genitals have an important purpose to the human body. Such a procedure is highly controversial since doctors are unsure what affect the removal would have on the body’s biochemistry” (Dr.Simoni). This is important because it explains that without genitals he could have serious complications. Secondly, doctors have never done this procedure so he would be a “ Guinea pig”. “This would be a brand new procedure and if something happens or there are complications, we don’t have any idea how to address them” (Dr. Simoni). This is important because if something was to go wrong during or after the surgery the doctors wouldn’t know how to deal with it and he could be left with serious issues. Therefore, Vinny Ohh should rethink the

First, Vinny Ohh doesn’t realize that this type of procedure would cause him major complications. The human body might not be able to function well without its external reproductive organs. Even though Vinny Ohh was born male, there’s still an example of females being negatively affected due to direct altering. For females, the any of those operations were found out to cause “chronic pain, infections, cheloids formation, primary infertility, birth complications, danger to the newborn and psychological consequences” (NCBI, 2011). It’s very important to consider the possibilities of your entire physiological makeup being permanently damaged when thinking

By 21 to 22 weeks after fertilization, the lungs gain some room to breathe air. This is called the age of viability because survival outside the womb becomes possible for some fetuses.

14 days. Fetal age is about 22 weeks when the mother is deciding the future of her unborn child. By

First trimester: By 12 weeks of pregnancy the foetus will be fully formed. The ovum grows and develops certain important parts of the baby’s body such as spinal cord, nervous system, gastrointestinal system, heart and lungs in the first four weeks from conception. The heart starts beating and brain and other organs forms by eight weeks. At this stage, the face is formed and arms and legs start to move. The baby grows to 3 inches long and

At the moment of birth the placenta (previously responsible for mediation in the respiratory, circulatory and hepatic functions between mother and a developing baby) is removed from the circulation and the neonates body must make several adjustments to undertake the respiratory and hepatic system roles as well as direct blood into its lungs to oxygenate it.

In the beginning the she seems calm and will stretch often. When the babies are about to arrive, she reaches under to the baby and helps it by grabbing the placenta. Then she cuts the umbilical cord then she eats the placenta, that is a very good source of iron and energy that will help her with the next days.

The relationship between breast cancer and functional ovaries was first observed by a British doctor, Thomas William Nunn. He reported breast cancer regression in a woman 6 months after she had reached menopause. Based on Mr. Nunn’s observation, a German surgeon, Albert Schinzinger, was then the first to propose removal of the ovaries as a potential therapy for breast cancer. This procedure was subsequently done for the first time in 1895 by a British physician, George Thomas Beatson. While some success was reported, it was largely unpopular at first, because it was associated with a high degree of

This stage is important during normal development because it is the first stage of lung development where the fetus can be birthed and still viable.

This surgery is performed to treat ovarian or other gynecological cancers, or infections caused by pelvic inflammatory disease. Occasionally, removal of one or both ovaries may be done to treat endometriosis, a condition in which the lining of the uterus (the endometrium) grows outside of the uterus (usually on and around the pelvic organs). The procedure may also be performed if a woman has been diagnosed with an ectopic pregnancy in a fallopian tube and a salpingostomy (an incision into the fallopian tube to remove the pregnancy) cannot be done. If only one fallopian tube and ovary are removed, the woman may still be able to conceive and carry a pregnancy to term. If both are removed, however, the woman is rendered permanently infertile. This procedure is commonly combined with a hysterectomy (surgical removal of the uterus); the ovaries and fallopian tubes are removed in about one-third of hysterectomies.

In chapter 3, I was very fascinated with the formation of a newborn. From the prenatal development that is divided into three periods-the germinal period which is after conception, the period of very rapid cell division and initial cell differentiation lasting for approximately 2 weeks. The embryonic period, is the second prenatal period, which last from implantation to the end of the second month after conception; all major structures and organs are formed. The final stage which is the fetal period, last from the end of the second month after conception until birth. I really love babies and I once wanted to be an OBGYN but I am very dramatic and emotional so I had to explore other options that revolved around my interest which led me to my

The first trimester is 0-13 weeks. This trimester is the most critical for your baby. In this stage your baby’s organs systems, and body stricter form. This is where your baby is also exposed to pathogens that can cause birth defects. This is also the stage in which miscarriage can happen. The backbone can flex,

When a fetus has experienced a gestation period of 37 weeks, it’s organ systems are defined mature and are able to support and sustain life.
