The male reproductive system
The diagram shows the male reproductive system.
Sperm cells are made in the testes (singular: testis). They travel along the sperm duct, into the urethra.
The seminal vesicles and the prostate gland make a sugary fluid for the sperm cells to swim in. The sugar helps to give the sperm cells energy to swim.
Question
1) Name the part of the male reproductive system that has each of these functions:
a: makes sperm cells
b: carries sperm cells from where they are made into the urethra
c: makes a sugary fluid for sperm cells to swim in.
The female reproductive system
The diagram shows the female reproductive system.
Egg cells are made in the ovaries. In an adult woman, one egg cell leaves one of the ovaries approximately each month. This is called ovulation.
The egg cell goes into the oviduct. Tiny hairlike structures on the oviduct walls, called cilia, move the egg cell slowly along the oviduct. This is where fertilisation can happen, if there are any sperm cells there.
The zygote that is formed by fertilisation carries on travelling down the oviduct, until it gets to the uterus. This is where it will develop and grow into a baby.
Question
2) Name the part of the female reproductive system that has each of these functions:
a: makes egg cells
b: where fertilisation happens
c: where the zygote develops into a baby.
