Reproductive System Flashcards
Testes
Make sperm via meiosis. The testes also produce testosterone, the male hormone
Vas Deferens
Sperm travel through this tube, joins with urethra
Prostate
Gland that produces a fluid that carries sperm during ejaculation. It surrounds the urethra
Penis
Male genitalia
Epididymis
Collects mature sperm which is eventually propelled through the vas deferens
Vasectomy
The tube is cut to prevent sperm leaving (and fertilizing an egg)
Circumcision
In circumcision, the foreskin is surgically removed, exposing the end of the penis.
Ovary
This is where the eggs are produced through cell division (MEIOSIS)
Uterus
The uterus consists of a body and a cervix. The cervix protrudes into the vagina.
Fallopian Tubes
The fallopian tubes are bilateral conduits between the ovaries and the uterus in the female pelvis. They function as channels for oocyte transport and fertilization
Vagina
Female genitalia
Cervix
The cervix is the lower end of the womb (uterus). It allows blood from a menstrual period and a baby (fetus) to pass from the womb into the vagina
Fraternal Twins
develop from the fertilization of two individual eggs. The babies do not look the same.
Zygote
A fertilized cell
Testosterone
Primary sex hormone and anabolic steroid in males
Menstruation
The process in a woman of discharging blood and other materials from the lining of the uterus at intervals of about one lunar month from puberty until menopause, except during pregnancy
Barrier method
Any type of birth control that puts a barrier between the penis and vagina (condom)
Placenta
Attaches to the fetus via the umbilical cord, supplies nutrients to the fetus during pregnancy. It is expelled after the baby is born
Ultrasound
Sound waves produce an image of the baby
Amniocentesis
Tests fatal cells for abnormalities, such as chromosome numbers
Pap test
Method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix or colon
Epidural
Procedure that injects a local anaesthetic in to the space around the spinal nerves in your lower back. This anaesthetic usually blocks the pain from labour contractions and during the birth very effectively
Trimester
A period of three months, especially as a division of the duration of pregnancy
Umbilical cord
The umbilical cord is the baby’s lifeline to the mother. It transports nutrients to the baby and also carries away the baby’s waste products. It is made up of three blood vessels – two arteries and one vein
IUD
T-shaped piece of plastic inserted into the uterus to provide birth control.
Ovulation
The release of an egg from your ovary, into your fallopian tube. It typically happens about 13–15 days before the start of each period
Caesarean section
When the baby is surgically removed from the mother. Performed when complications make vaginal delivery risky
Fertilization
The action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote
Plan B
Plan B One-Step contains the hormone levonorgestrel — a progestin — which can prevent ovulation, block fertilization or keep a fertilized egg from implanting in the uterus. The morning-after pill is a type of emergency birth control (contraception)
Contractions
Contractions of muscles occur and become faster and faster, this timing can be used to precut the progression of labor. Dilation of the cervix allows for baby to pass through
Diaphragm
A diaphragm is a dome-shaped, silicone cup that’s inserted in the vagina hours before sex to prevent pregnancy. To work effectively, it needs to be used with spermicide to block sperm from reaching eggs
