8
Q

process of fertilization

A

spermatozoon enters the ovum and the two nuclei containing the parents chromosomes merge. 23 from the sperm and 23 from chromosomes from the ovum. Ovum now called zygote is ready for the first mitotic cell divison

9
Q

process of implantation

A
upper uterus (fundus)
rich supply of blood and optimal gas exchange and nutrition
uterine lining is thick in fundus preventing placenta from attaching so deeply that it does not easily detach
upper uterus limits blood loss after birth due to strong interlacing muscle fibers
10
Q

role of the following in pregnancy and labor:

Q

role of the following in pregnancy and labor:

Q

role of the following in pregnancy and labor:

role of the following in pregnancy and labor: pelvic shape and size

??
