Reproductive System Flashcards
Penis
The sex organ that males use to inseminate females
How does the penis work
It consists of the urethra and erectile tissue that fills with blood during copulation
Urethra
A tube that is in the penis which connects to the balder in order to allow urine to be expelled from the body
Epididyms
A collided tube at the back of the testes. Where sperm matures and is stored before release
Vas deference
Tune that transport sperm from the epididyms to the prostate gland
Testes
Pair of organs that’s responsible for the production of sperm.
I hate do the testes do
They produce testosterone which means the male sex hormone this is responsible for the development of male characteristics
Prostate gland
It produces a fluid which protects the sperm and it expels sperm into the urethra upon ejaculation
Oviducts
The tube that connects the ovaries to the uterus and along which eggs travel during reproductive system
Ovaries
These two organs are responsible for the production of eggs which subsequently travel down the oviducts
Female reproductive system
Vulva
The entrance of the vagina
Vigina
A muscluar tube which receives the penis during compulation
Cervix
The entrance of the uterus located at the other end of the vagina
Uterus
Commonly known as the womb
The oestrous cycle
Describes the periods when a female mammal is fertile and sexually active and when they are not
What are the four hormones
Oestrogen
Progesterone
Follicle stimulating hormone
Lutenising hormone
Oestrogen
Which is secreted by follicles as they grow
Progesterone
Secreted by the remains of the follicles
Follicle stimulating hormone (FSH)
Luteinsing hormone (LH)
Both secreted by the pituitary gland
5 sexual reproduction stages
Copulation
Fertilisation
Implantation
Gestation
Partition
Copulation
Known as mating when the males penis enters the female vagina
Fertilisation
Semen contains millions of sperm which travel through the cervix into the uterus and to the oviducts
Implantation
Whilst fertilisation has been taking place the release of progesterone caused the lining of the uterus to thicken
Gestation
Part of the blastocyst becomes the embryo itself and part of it becomes the placenta
Partition
Giving birth
Oviparous
Animals embryos develop in ges which hatch outside the body
Oestrogus cycle
Proestrus
Estrus
Diestrus
Metestrus
