|
Shedding
|
|
The more public / every-day term used to describe menstruation
|
Period
|
|
The purpose of the menstrual cycle is to prepare the woman's body and uterus for a potential _________
|
Pregnancy
|
|
The name of the biological process when the egg is released by the ovaries
|
Ovulation
|
|
The menstrual cycle is 100% controlled by four ________, which are mainly produced ans secreted by glands (will be mentioned later)
|
Hormones
|
|
The biological process that will start around the age of 50, where, by the end of the process, the woman's fertility (ability to become pregnant) will cease to exist
|
Menopause
|
|
The Three Phases of the Menstrual Cycle
|
The First Phase - Called the __________ phase - This phase begins when the lining of the uterus sheds and ends with the second phase. The _______ levels increase, which will cause the ______ of the uterus, and the ________-stimulating hormone (FSH) causes follicles (shells containing egg) in the ovaries grow. This phase ends when one developed follicle eventually releases |
Follicular phase
|
|
Estrogen
|
|
Lining
|
|
Follicle-stimulating hormone
|
The Second Phase - Called the _________ phase. The sudden increase of the hormone ___________ hormone (LH) will cause the developed egg to be released and travel through the _________ tubes, where conception is most likely to take place |
Ovulatory phase
|
|
Luteinizing
|
|
Fallopian tubes
|
The Third Phase - Called the ______ phase. As the egg travels through the _________ tubes, the rise of the ____________ hormone will help maintain and prepare the lining of the uterus for a pregnancy. |
Luteal phase
|
|
Progesterone
|
|
The Fourth Stage - Called ______ phase. If the fertilised egg doesn't attach itself to the lining of the uterus, the estrogen and progesterone hormone will decrease, causing the lining of the uterus to shed, and that's when the girl will receive her monthly period (menstruation)
|
Menses phase
|
|
|
Conception
|
|
When the egg and sperm collides in the fallopian tubes
|
Conception
|
|
If the sperm fertilises the egg, it becomes a ______, and will travel towards the uterus
|
Zygote
|
|
As the ______ travels down towards the uterus, hormones will form the lining of the uterus, also called the ___________, and this lining of the uterus will be formed and shed for each new menstrual cycle
|
Endometrium
|
|
If the _________ reaches the uterus and the temporary organ attaches to the lining of the uterus, an ___________ has taken place and the pregnancy is biologically confirmed
|
Implantation
|
|
As the _____ travels down towards the uterus, the ______ will rapidly perform cell division, and the cell division will form two different structures: the first structure being the temporary organ that will attach to the uterine wall and will be the resource of oxygen and nutrients to the baby as its growing in the uterus, the second structure being a __________, otherwise known as what will eventually become the fetus.
|
Placenta
|
|
Blastocyst
|
|
|
Pregnancy
|
|
The length of an average pregnancy (months, weeks and days)
|
9 Months
|
|
40 Weeks
|
|
280 Days
|
|
When a pregnancy has taken place, the ovaries will start secreting this hormone that is also used as an indicator to spot a pregnancy through a blood sample
|
Human Chorionic Gonadotropin (HCG)
|
|
1-2 - The sperm merges with the egg and starts moving down towards the uterus, and the merged egg and sperm successfully attaches to the lining of the uterus through the temporary organ
|
Germinal Stage
|
|
Week 3-8 - During this stage, the bundle of cells will start taking human form becomes an embryo. The embryo's limbs and organs will start forming and by the end of this stage, most of the organs and systems will take shape; heart, brain, spinal cord, legs, arms, and around six weeks into the pregnancy, a heart beat will emerge
|
Embryonic Stage
|
|
Week 9-40 - This stage is when the embryo turns into a fetus; the sex is assigned, the organs will start growing, hair and nails emerge, at around week 20, the woman can be able to feel the fetus move inside the uterus, the majority of growth and weight takes place during this stage
|
Fetal Stage
