1. Reproductive Organs (in humans)
1.1
What is the function of male and female reproductive systems in humans?
To allow reproduction (the production of offspring/children)
1.2
What is fertilisation?
The joining of sperm and egg cells to form an embryo
1.3
What is the function of the male reproductive system?
To produce sperm cells and release them inside a female
1.4
What are the main parts of the male reproductive system?
1.5
What is the function of the testes?
To produce sperm cells and the male sex hormones
1.6
What is the function of the scrotum?
To contain the two testes
1.7
What is the function of the glands?
To produce nutrients that help keep sperm alive
1.8
What is semen?
The mixture of sperm and nutrient-rich fluid produced by the glands
1.9
What is the function of the sperm ducts?
To carry sperm from the testes to the penis
1.10
What is the function of the urethra?
To catty urine from the bladder or sperm from the sperm duct
1.11
What is the function of the penis?
To carry urine or semen out of the body
1.12
What is the function of the female reproductive system?
To produce egg cells and support the growth of an unborn baby (foetus) before birth
1. Reproductive Organs (in humans)
1.13
What are the main parts of the female reproductive system?
1.14 What is the function of the ovaries?
1.15 What is the function of the oviducts?
1.18 What is the function of the vagina?
2. Fertilisation
2.1 What are gametes?
To store and release egg cells
To carry an egg to the uterus
To receive sperm during sexual intercourse
Reproductive cells (e.g. sperm and egg cells)
1.16
What is the function of the uterus?
The place where the foetus (unborn baby) develops
1.17
What is the function of the cervix?
To separate the vagina from the uterus (it is a ring of muscle)
2.2
What are the main steps in the process of fertilisation?
1. An egg is released from the ovary and travels through the oviduct towards the uterus
2. During sexual intercourse, ejaculation occurs in which semen (containing sperm) is released from the penis into the vagina
3. Sperm cells swim from the vagina through the cervix
4. Sperm cells then travel to the oviduct
5. If a sperm cell meets an egg cell, fertilisation occurs
2.3 Where does fertilisation take place?
2.4 What is a foetus?
In the oviduct
An unborn baby
