Chapter 16 - Female Reproductive System Flashcards
Pregnancy and Birth
The membranous sac filled with fluid that holds the fetus; also called amnion (root: amnio)
amniotic sac
A system of rating an infant’s physical condition immediately after birth. Five features are rated as 0, 1, or 2 at one and five minutes after delivery and sometimes thereafter
Apgar score
The outermost layer of the embryo that, with the endometrium, forms the placenta (adjective: chorionic)
chorion
Breast fluid that is secreted in the first few days after giving birth, before milk is produced
colostrum
A fetal blood vessel that connects the pulmonary artery with the descending aorta, thus allowing blood to bypass the lungs
ductus arteriosus
The stage in development between the zygote and the fetus, extending from the second through the eighth week of growth in the uterus (root: embry/o)
embryo
The union of an ovum and a spermatozoon
fertilization
The developing child in the uterus from the third month to birth (root: fet/o); adjective: fetal
fetus
A small hole in the interatrial septum in the fetal heart that allows blood to pass directly from the right to the left side of the heart
foramen ovale
The period of development from conception to birth
gestation
Pregnant woman
gravida
A hormone secreted by the embryo early in pregnancy that maintains the corpus luteum so that it will continue to secrete hormones
human chorionic gonadotropin (hCG)
The secretion of milk from the mammary glands
lactation
A pituitary hormone that stimulates contractions of the uterus. It also stimulates release (“letdown”) of milk from the breasts
oxytocin
Woman who has produced a viable infant. Multiple births are considered as single pregnancies
para
Childbirth (root: nat/i); labor (root: toc/o)
parturition
The organ, composed of fetal and maternal tissues, that nourishes and maintains the developing fetus
placenta
A group of hormones with varied effects, including the stimulation of uterine contractions
prostaglandins
The structure that connects the fetus to the placenta. It contains vessels that carry blood between the mother and the fetus
umbilical cord
The fertilized ovum
zygote
Termination of a pregnancy before the fetus is capable of surviving outside the uterus, usually at 20 wk or 500 g.
abortion
A congenital separation of the upper lip
cleft lip
A congenital split in the roof of the mouth
cleft palate
Inflammation of the breast, usually associated with the early weeks of breastfeeding
mastitis

ovarian follicle

perineum

B, C, A
For the first 2 months of growth, the developing offspring is termed a(n):
embryo
A trimester consists of approximately:
3 months
The hormone produced early in pregnancy that maintains the corpus luteum is:
human chorionic gonadotropin
The foramen ovale and ductus arteriosus allow blood in the fetus to bypass the:
lungs
A nullipara is a:
woman who has never given birth
The production of colostrum is followed by:
lactation
During development, the zygote becomes a(n):
embryo
The length of pregnancy is often calculated from the:
LMP
Mastitis is:
inflammation of the breast
