Describe of process of reproduction/fertilization. ✅An oocyte is created through the
process of oogenesis. During ovulation, the ovum (mature oocyte) drops into the distal
third of the fallopian tube. During intercourse, the sperm travels through the vagina, past
the cervix, then into the uterus. The sperm swims around to find the ovum in the distal
third of the fallopian tube. When the sperm finds the ovum, it fertilizes the egg. When
the nucleus of the fertilized cell splits, it forms a zygote (day 1). For a few days, the
zygote keeps splitting until it gets to 16 cells, then it is called a morula. It becomes at
,blastocyst at day 5 then implants into the endometrium. This entire time the cell is
traveling from the distal third of the fallopian tube to the fundus of the uterus.
The main hormone involved with labor and delivery. It causes labor contractions, and

These two hormones peak right before ovulation, to cause the ovum to be released into
the fallopian tube. ✅FSH and LH
How long does it take for the fertilized egg to travel from the ampulla of the fallopian
tube to the uterus to implant? ✅Up to 7 days, it varies.
A fertilized egg ✅Zygote
The process of the blastocyst implanting in the uterus releases which hormone,
commonly used for pregnancy tests? ✅HCG
The period from fertilization (Day 0) to 2 weeks is called what? ✅Pre-embryonic period
Which period is most critical in the development of the organ systems and main features
of a fetus? ✅Embryonic period (Week 2-8)
What are the three layers of the blastocyst? ✅1. Ectoderm
2. Mesoderm
3. Endoderm
In the fetal period, the fetus grows how much per day? ✅1.5%
The term for the uterine lining during pregnancy (endometrium), which forms the
maternal part of the placenta. ✅Decidua
# of times a woman has been pregnant (including current pregnancy) ✅Gravida
# of times a woman has given birth, longer than 20 weeks gestation ✅Parity

The capacity to live outside the uterus; there are no clear limits of gestational age or
weight. Infants born at 22 to 25 weeks of gestation are considered to be on the

A bluish discoloration of the cervix, vagina, and labia resulting from increased blood
flow. It can be observed as early as 6 to 8 weeks after conception, and its presence is
