Q

ovaries

A

The primary female sex organs are the ovaries. Each female has two ovaries that are located on either side of the uterus. They are almond-shaped organs that are responsible for producing the ova, the female reproductive cells.

Q

purpose of the fallopian tube

A

The purpose of the fallopian tube is to collect an ovum or egg after it has been discharged from the ovary and to propel it through the tube toward the uterus.

Q

Fertilization, also called conception

A

Fertilization, also called conception, is when an ovum joins with a sperm cell to form a zygote. This process typically occurs within the fallopian tubes.

24
Q

vagina

A

The vagina is a tube that extends from the vestibule of the vulva to the uterus. It functions to discharge menstrual fluid and as a passageway for the fetus during childbirth. The vagina also receives the male penis during sexual intercourse.

25
Q

vulva

A

The vulva is the external female genitalia

26
Q

mons pubis

A

The vulva is the external female genitalia (Figure 7.8). It contains the mons pubis, which is a triangular-shaped pad of fatty tissue that is covered with pubic hair.

27
Q

labia majora and labia minora

A

The labia majora and labia minora are folds of tissue that are on either side of the vaginal opening.

28
Q

vestibule

A

The vestibule is the opening to the vagina that also contains the opening of the urethra (the urinary meatus in Figure 7.8) and the excretory ducts of the Bartholin glands.

29
Q

clitoris

A

The clitoris is a small organ that has erectile tissue and is responsible for sexual pleasure during intercourse.

30
Q

Breasts

A

Breasts are organs that contain mammary glands

31
Q

mammary glands

A

Breasts are organs that contain mammary glands (Figure 7.9). They are located on the chest and are responsible for making milk after childbirth.

32
Q

areola

A

The areola is the dark, pigmented section in the skin over each breast.

33
Q

nipple

A

The areola contains the nipple and is where the lactiferous or mammary glands secrete milk when a baby sucks the breast.

34
Q

prolactin

A

After childbirth, the hormone prolactin is produced by the anterior pituitary gland. This hormone stimulates the mammary glands to produce milk.

35
Q

Colostrum

A

Colostrum is the milk that is immediately produced after childbirth. Mature breast milk is produced 2-3 days after childbirth and is the best food available to the newborn infant. Babies can survive on their mother’s milk exclusively for up to 6 months after birth.

36
Q

menstrual cycle

A

The menstrual cycle is crucial to the normal functioning of the female reproductive system. It is a cycle of changes that happen within the breasts, uterus, vagina, and ovaries that are stimulated by several hormones to produce a mature ovum that can be fertilized.

37
Q

menarche

A

The first menstrual cycle is called menarche, and it occurs at the end of puberty, marking a mature reproductive system capable of producing offspring. A typical menstrual cycle is 21-35 days in a mature female, and it typically occurs from the teenage years to when a woman is in her 40-50s.

38
Q

menopause

A

When a female stops menstruating, this is referred to as menopause.

39
Q

follicular phase

phases of the menstrual cycle and the different hormones levels

A

The first phase of the menstrual cycle is the follicular phase, and it starts on the first day of menstruation. This phase is when the endometrium sheds through a bloody discharge that lasts, on average, for five days.

40
Q

ovulatory phase

phases of the menstrual cycle and the different hormones levels

A

The next phase is the ovulatory phase, and it is marked by an increase in estrogen, luteinizing hormone, and follicle-stimulating hormone. Estrogen stimulates the endometrium to thicken and vascularize again, and FSH and LH stimulate the ovaries to produce a follicle that ruptures on the cortex, or surface, of the ovary to release an ovum and then produce progesterone for the third phase of the menstrual cycle. This process is called ovulation.

41
Q

luteal phase, also called the secretory phase

phases of the menstrual cycle and the different hormones levels

A

The final phase of the cycle is the luteal phase, also called the secretory phase. The ruptured follicle is now called a corpus luteum and it produces progesterone. Progesterone functions to thicken the mucus produced by the cervix to make it difficult for sperm or bacteria to enter the vagina. Estrogen continues to stimulate the thickening of the endometrium. If the ovum is not fertilized, the corpus luteum dissolves, and progesterone and estrogen production decreases. A new menstrual cycle then starts again.

42
Q

pregnant

A

If the ovum is fertilized by a sperm during the ovulatory phase of the menstrual cycle, a woman is pregnant

43
Q

Pregnancy

A

Pregnancy is the time between conception and the birth of the fetus. A normal pregnancy is 40 weeks long, and this is also called the gestation period.

44
Q

gestation period

Pregnancy

A

A normal pregnancy is 40 weeks long, and this is also called the gestation period.

45
Q

trimesters

A

Pregnancy is divided into three trimesters that are each 3 months long. There are three stages of human development:

46
Q

pre-embryonic stage

trimesters

A

The pre-embryonic stage is the first 14 days after conception

47
Q

embryonic stage

trimesters

A

The embryonic stage is weeks 3-9 after conception. The embryonic period is the time where all the major organs and body systems are formed

48
Q

fetal stage

trimesters

A

At 9 weeks after conception, every organ system is present, and the embryo is now called a fetus.

49
Q

After 9 weeks

Pregnancy

A

After 9 weeks, the fetus continues to grow and mature until it is ready for birth around 40 weeks. The organ systems of the body begin to function, and the fetus grows muscle and fat tissue. Figure 7.12 shows a full-term fetus in the uterus. As a pregnancy progresses, the fundus or top of the uterus extends outside of the pelvis and into the abdominal cavity.

50
Q

fundal height

A

A useful measurement, called the fundal height, is obtained throughout pregnancy. It is the distance in centimeters from the pubic symphysis to the fundus. The fundal height is used to assess fetal growth and development throughout pregnancy. After 24 weeks of pregnancy, the fundal height in centimeters can match the number of weeks a woman has been pregnant.

51
Q

Labor

A

Labor is the process of the birth of the fetus. The myometrium of the uterus contracts to push the baby out of the uterus and through the vagina, or birth canal. Labor can start hours to weeks before the baby is born.

52
Q

Signs of impending labor

A

Signs of impending labor include
Braxton Hicks contractions, which are irregular, painless contractions that start in the second trimester;

increased vaginal discharge,

lightening where the baby descends into the pelvis,

bloody show of mucus mixed with dark brown blood, which is the dislodging of the mucus plug from the cervix, and

the rupture of membranes as the amniotic sac ruptures.

53
Q

Active labor

A

Active labor has three stages.

54
Q

dilation stage

Active labor has three stages.

A

The first stage is the dilation stage where the cervix thins and dilates to allow the baby to pass through.

55
Q

expulsion

Active labor has three stages.

A

The second stage is expulsion, which is the time from when the cervix is fully dilated to the actual delivery of the baby.

56
Q

placental stage

Active labor has three stages.

A

The third stage is the placental stage, which is the delivery of the placenta.

57
Q

placenta

A

The placenta is a temporary organ that provided the nourishment and oxygen to the baby from the mother’s blood supply during pregnancy. It is connected to the baby through the umbilical cord. The placenta can also be called the afterbirth.

58
Q

postpartum period

A

The postpartum period is the time from childbirth through 6 weeks after birth. During this time, the female reproductive organs heal from childbirth and return to their pre-pregnancy size.
