Conception to Birth About one month before conception almost all adult produce thousands of sperm each second. The number of chromosomes in each sperm produced is half the normal number 23 instead of 46. They take a month or so to travel from a testicle through a long tube. Each sperm counts human DNA but only one complete a set of chromosomes. One day before conception the woman ovulates and produces one mature ovum.
Why is it important? 7- Why is it important for a woman who suspects she is pregnant to go to the doctor? 8- How can you treat Phenylketonuria? Answers Part I 1. Fertilization: it is the process in which a female gamete (ovum) and a male gamete (sperm) come together in the female’s body, initiation
Redraw the chart to show your changes. 4. Describe in detail a process that the hospital could analyze, besides the ones mentioned in this case. 1. Pregnant women could preregister at 20 weeks when they come to the hospital to get the ultra sound done to determine the baby’s sex.
Physical Development Physical development includes motor skills, co-ordination and the influence of hormones. Infancy ( 0-3) Human development begins after the union of male and female gametes or germ cells during a process known as fertilization (conception). When this happens only half of the fertilised eggs become babies. 3 days after fertilisation the egg is the size of a pin head and becomes embedded in the uterus. Labour begins when a women’s water break, this is the amniotic fluid that protects the baby.
Risks and benefits of amniocentesis Chelsea Webb SCIN132 D011 Win 12 Professor Kennard Sproul The risks and benefits of amniocentesis Amniocentesis is an invasive procedure used to collect cells from the fetus for genetic testing. Amniocentesis is done in a pregnant woman of around 15 to 20 weeks of gestation. Amniotic fluid is the fluid around the fetus in the uterus. The procedure involves taking the amniotic fluid around the fetus to collect cells that are shed from the skin of the fetus. These cells are used in different tests like karyotype i.e., knowing the number and type of chromosomes.

IVF can take many tries but, here is an explanation of what IVF is; In IVF, this process of fertilisation happens outside the woman’s body. A woman’s eggs are specially removed during basic surgery and then fertilised in a laboratory using sperm that has been given as a sperm sample. Next, the fertilised egg, called an embryo, is surgically implanted into the woman's womb.
Fetal Blood Flow The process of gas exchange between the mother and an unborn baby has several steps. A large flat organ that is inside the uterus of a pregnant women is called the placenta. The placenta is attached to the fetus which is through the umbilical cord. The placenta is a very important function during the pregnancy of a women. The transfer is very vital in enabling the right nutrients that are transported through to the mother from the placenta and then to the fetus which dismisses waste that is produced by the fetus then goes back through the placenta than into the maternal blood stream which it is then released by the mother.
The type of sperm (X or Y) that fertilizes an egg can be chosen, which is used to determine the sex and genes of the baby. The embryos can be screened for genetic diseases, and only selected embryos are implanted back into the mother’s womb. This technique is called Pre-implantation Genetic Diagnosis or PGD. (Bionet par. 2) Michael Lemonick, a writer for Time, shows in his article “Designer Babies” that these techniques allow doctors and parents to reduce the chance that a child will be born with a genetic disorder.
The Chorionic villi are the looping capillaries of the fetal venules and arterioles, it is here were all the gas, nutrient, and waste exchange occurs between the maternal and fetal blood. (Murdoch) The top “layer” is a mucous membrane called the decidua, which is where the placenta connects to the endometrium of the uterus. (Gray) This decidual layer does not remain throughout the entire pregnancy; within a few weeks of implantation, the chorion of the placenta degrades the layer and leaves it thin and permeable to maternal uterine blood it can empty into spaces around the chorionic villi so exchange can take place. (Gray) The placenta is made up of both maternal and fetal tissues. The maternal side is
