She does not release an ____ cell when she has an orgasm but she may become moist.If no egg is present in the fallopian tubes the sperm will _____ in a few days.If an egg is present in the _________ ______ fertilization may take place.Takes
4Fertilization Process Sperm surround the egg – releasing _______ to break down the protective cells surrounding the mature egg.Only the ______ of one sperm enters the egg. No other sperm may enter because the egg cell outer ________ changes sealing out all other sperm.The two nuclei combine – 23 chromosomes from the male and 23 from the woman combine to form __ pairs of chromosomes.Chromosomes are small thread-like structures in the nucleus of the cell that are made up of ______, carriers of hereditary traits, that determine which traits we inherit from our parents.Sex of the child:Egg has a ______ chromosome pattern geneSperm has a ______ or ______ chromosome pattern gene______ chromosome pattern will be a girlXY chromosome pattern will be a ________The _________ determines the sex of the child
5Development of a Human Being With in the first 36 hours the fertilized egg (zygote) cleaves (divides) forming two identical connected cells, 4 cells, 8 cells, 16 cells, until a hollow ball of cells is formed (blastula). Once the blastula is implanted in the uterus (1 to 2 weeks) it is called an embryo. This cleaving process will continue for the next 9 months.Super Structures:______: looks like the yellow part in an egg – it provides nourishment for the embryo until the placenta is developed.______holds the embryo to the _______ ____ and becomes the umbilical cord___________ cord – rope like structure –width of your thumb, 14 to 36 inches long, & all nourishment and waste pass through this structure. It has no _________.Placenta – network of _______ ______ and other tissues which is attached to the wall of the uterus. It serves as a ________ point for all nourishment & waste. The blood of the mother and the fetus never _________ . The blood vessels grow side by side & are not _______. Blood type of the fetus can be _________ from that of the mother.
6Development of a Human Being - Terms Super Structures:Placenta – there is a space between mother and fetuses blood systems. ________ & ________ diffuses across this space._______ Sac: fluid filled membrane that surrounds the growing embryo and fetus. Called the bag of water. Functions: controls temperature, provides room to grow and move, and protects the fetus from injury.__________: a fertilized egg (ovum)_________: A hollow ball a cells that divides as it travels to the uterus. It gets its nourishment from the blood enriched walls of the womb._____________: implanted blastocyst in the uterus_______ :from the 10th week until the birth and now looks like a tiny human being.
