human reproductive system Flashcards
1
Q
what is the function of sex glands?
A
produce nutrient fluid to nourish the sperm
2
Q
what is the function of sperm duct?
A
carries sperm from the testes to the urethra
3
Q
urethra?
A
- a tube that allows sperm to pass through during ejaculation
- allows urine to be removed from the body
4
Q
what is the function of the testis?
A
- produces sperms
- produces male sex hormones that control sexual development in the body
5
Q
what is the function of the penis?
A
deposits semen (a white liquid made up of nutrient fluid and sperm) into the vagina during ejaculation
6
Q
what happens during sexual intercourse? (male)
A
- sperm produced by both testes travel along the sperm ducts and enter the urethra
- sex glands release a fluid to nourish the sperm
- the penis deposits semen containing millions of sperm cells deep into the vagina
7
Q
what is semen?
A
the mixture of nutrient fluid and sperm
8
Q
what is ejaculation?
A
the process in which semen leaves the male reproductive system.
9
Q
what is oviduct
A
- a tube through which an egg is released from the ovary
- fertilisation usually take place here
9
Q
functions of the ovary?
A
- produces eggs
- produces female sex hormones that control the sexual development in the body
10
Q
what happens during ovulation?
A
- an ovary releases an egg cell, which then enters the oviduct.
- ## if the egg is fertilised, it will travel towards the uterus to be implanted in its wall.
11
Q
what is uterus?
A
- a muscular organ where an embryo develops into a foetus during pregnancy
- contains a lining called the uterine lining, which thicken to prepare for implantation and breakds down when no fertilisation occurs
12
Q
what is the cervix?
A
- opening of the uterus
- connects the uterus to the vagina
13
Q
vagina?
A
- sperm are deposited here
- also known as the birth canal
14
Q
what is the process of fertilisation
A
- the penis deposits semen containing sperm cells in the vagina
- the sperm cells swim to the cervix, into the uterus, then the oviduct
- a sperm cell meets an egg cell in the oviduct
- fertilisation occurs when the nucleus of the sperm cell fuses with the nucleus of the egg cell. all other sperm cells die
