26
What is the process of fertilization and implantation?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula (3 days). Once it reaches the uterus, the morula becomes a blastocyst (4 days). The blastocyst then burrows into the uterine lining — a process called implantation. (6 days)
27
What is the structure of the placenta?

28
What is the function of the placenta?
o Provides nutrients (O2) and removes waste (CO2)o Metabolizes drugs and other substances
o Produces hormones estrogen/progesterone for maintenance of pregnancy
§ Estrogen stimulates uterine development to provide environment for baby
§ Progesterone relaxes uterine muscle to prevent spontaneous abortion
o When Human Chorionic Gonadotropin is released it produces the placenta and begins to grow. An increase in HCG levels =indication of pregnancy
o Corpus luteum main source of estrogen and progesterone until month 3. After that the placenta is in charge.
29
What is the structure of the umbilical chord?

30
What is the function of the umbilical chord?
o Transport O2 and nutrients from Mom to baby and waste back to maternal blood
o Permits free movement for baby within the membranes
o arteries carry deoxygenated blood while veins carry oxygenated blood (when cord is cut those will close and switch functions)
31
What kind of blood do the arteries carry?
deoxygenated blood
32
What kind of blood do the veins carry?
oxygenated
33
What are the three fetal valves called in fetal circulation?
