Reproductive System Flashcards
(31 cards)
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
Is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra
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.
The uterus maintains an environment for accepting a fertilized egg.
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
The vagina has 3 main functions: provides a passageway for blood and mucosal tissue from the uterus during a woman’s monthly period
Cervix
The cervix acts as the door to the uterus which sperm can travel through to fertilize eggs.
Fraternal Twins
Develop from the fertilization of two individual eggs.
The babies do not look the same.
Zygote
A fertilized egg is called a zygote
An egg is usually a few days old before it implants in the uterus
Testosterone
is a sex hormone that plays important roles in the body
Menstruation
is the elimination of the thickened lining of the uterus (endometrium) from the body through the vagina
Barrier method
Control prevent pregnancy by blocking sperm. This stops the sperm from reaching an egg.
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 (fetal test)
sound waves produce an image of the baby
You can tell the sex of the baby and its position
Amniocentesis
Tests fetal cells for abnormalities, such as chromosome numbers
Pap test
Is the most common test used to look for early changes in cells that can lead to cervical cancer. It involves gathering a sample of cells from the cervix. The cervix is the part of the uterus that opens to the vagina.
Epidural
This anaesthetic usually blocks the pain from labor contractions and during the birth very effectively. With an epidural you can usually move and can push your baby out when you need to.
Trimester
A pregnancy is divided into trimesters: the first trimester is from week 1 to the end of week 12. the second trimester is from week 13 to the end of week 26. the third trimester is from week 27 to the end of the pregnancy.
Umbilical cord
The umbilical cord is a tube that connects you to your baby during pregnancy. It has three blood vessels: one vein that carries food and oxygen from the placenta to your baby and two arteries that carry waste from your baby back to the placenta.
