4
Do Now Sequence the path that sperm follow in leaving the human body. ___ urethra and penis ___ testes ___ vas deferens ___ prostate gland and seminal vesicle ___ epididymis Explain the function of at least three of these structures Answer the following questions in your science notebooks.
5
What is the main function of the female reproductive system? To produce gametes (__________) by meiosis To accept male gametes (__________) To nourish and develop __________________ To produce female sex ______________
6
What is the basic anatomy and physiology of the female reproductive system? ______________ fallopian tubes uterus cervix _______________
7
What is fertilization? _____________is the union of a sperm cell and an egg cell to form a _________________. Occurs in upper third of Fallopian tube Only ____________ sperm can fertilize an egg
8
What cellular processes make it all happen? ____________or the increase in the number of cells. _________________ or the arrangement of the cells into specific organs. _________________or the specialization of cells to perform specific tasks and functions.
9
What is implantation? Zygote divides several times to form a hollow ball of cells called a ______________. More cellular divisions result in a ______________, a ball of cells with a large fluid cavity. Blastocyst burrows into the lining of the uterus during _________________.
10
What happens after implantation? Implanted blastocyst gradually sorts itself into three layers forming a ______________. All the organs and tissues of the embryo will be formed from these three layers by cell differentiation.
11
What is neurulation? _________________is the development of the nervous system. Neural folds create neural tube. One end of the neural tube will develop into the brain, the other end develops into the ______________ cord.
12
What are some important extraembryonic structures?
