Worksheet Overview

QUESTION 1 of 10

Human Reproduction - important or not very important? Dumb question!

 

So, knowing the facts is vital. Amazingly, lots of folks think they know it - but in reality they're totally mixed up. Time for a reality check - in this worksheet are some basic questions covering where the bits are and what they do. Some of the other worksheets will look at this in more detail, but you need to make sure the foundations are really solid before you try to build on them!

It's important to be able to recognise the major parts of the human reproductive system, so see whether you can match the labels correctly with the names in the female reproductive system:

 

Column A

Column B

P
ovary
Q
uterus
R
oviduct
S
vagina

Now see whether you can do the same for the male reproductive system:

 

Column A

Column B

V
scrotum
W
penis
X
sperm duct
Y
testis
Z
urethra

Knowing the layout of the various parts is important. You also need to know what they do. Over the next few questions, you must choose which part of the reproductive system is being described.

 

First off, in which part does the baby develop?

vagina

scrotum

ovary

uterus

Where are the eggs made?

ovary

testis

oviduct

penis

Where are the sperms made?

ovary

testis

oviduct

penis

Where does the sperm meet the egg and fertilise it?

urethra

vagina

oviduct

uterus

These last few questions are simply to check how well you understand the meanings of certain reproductive terms.

 

Pick the word from the list that describes the length of time the baby spends in the womb until it is born (generally called PREGNANCY).

gestation

ovulation

menstruation

fertilisation

Pick the word from the list that describes the moment when the sperm enters the egg.

gestation

ovulation

menstruation

fertilisation

Pick the word from the list that describes the monthly removal and replacement of the wall of the uterus (generally called a 'period').

gestation

ovulation

menstruation

fertilisation

Pick the word from the list that describes the monthly release of an egg into the reproductive system.

gestation

ovulation

menstruation

fertilisation

  • Question 1

It's important to be able to recognise the major parts of the human reproductive system, so see whether you can match the labels correctly with the names in the female reproductive system:

 

CORRECT ANSWER

Column A

Column B

P
vagina
Q
uterus
R
oviduct
S
ovary
EDDIE SAYS
So, did you remember that the womb is properly called the uterus? That's where the baby develops. The eggs are made in the ovary and the proper name for the egg is an OVUM, so the OVIDUCT is the tube where the egg waits to be fertilised.
  • Question 2

Now see whether you can do the same for the male reproductive system:

 

CORRECT ANSWER

Column A

Column B

V
penis
W
testis
X
urethra
Y
sperm duct
Z
scrotum
EDDIE SAYS
OK, how was that? The testes are surrounded by the scrotum and connected to the penis by the sperm duct - that's the tube the sperms travel down. The tube that runs down the middle of the penis, carrying both sperm and urine is called the URETHRA.
  • Question 3

Knowing the layout of the various parts is important. You also need to know what they do. Over the next few questions, you must choose which part of the reproductive system is being described.

 

First off, in which part does the baby develop?

CORRECT ANSWER
uterus
EDDIE SAYS
It's definitely not the scrotum, as that's a male part. The ovary makes the eggs and once one of them is fertilised it will develop into a baby in the uterus.
  • Question 4

Where are the eggs made?

CORRECT ANSWER
ovary
EDDIE SAYS
The testis and penis are part of the MALE reproductive system, so it can't be either of them. The eggs are made in the two ovaries and are released into the oviduct where they wait for the sperm.
  • Question 5

Where are the sperms made?

CORRECT ANSWER
testis
EDDIE SAYS
This time, it can't be the ovary or the oviduct, as they are part of the FEMALE reproductive system - remember? The sperms are made by the millions in the two testes and pass up the sperm duct and into the penis during ejaculation.
  • Question 6

Where does the sperm meet the egg and fertilise it?

CORRECT ANSWER
oviduct
EDDIE SAYS
The sperms meet the egg after they've swum through both the vagina and the uterus and then into the oviduct. The egg was released from the ovary into the oviduct and it waits there to be fertilised by the sperm. By the way, the urethra is the tube that carries the urine away from the bladder.
  • Question 7

These last few questions are simply to check how well you understand the meanings of certain reproductive terms.

 

Pick the word from the list that describes the length of time the baby spends in the womb until it is born (generally called PREGNANCY).

CORRECT ANSWER
gestation
EDDIE SAYS
The proper term for pregnancy is the GESTATION PERIOD. In humans that's around 9 months (40 weeks) but it varies a lot amongst mammals: elephants have a 22 month gestation while both dogs and cats are around 9 weeks.
  • Question 8

Pick the word from the list that describes the moment when the sperm enters the egg.

CORRECT ANSWER
fertilisation
EDDIE SAYS
The moment the sperm enters the egg, the egg has been FERTILISED. That is when the male half of the genetic information (in the sperm's nucleus) joins the female half of the information (in the egg's nucleus), resulting in a brand new set of genes in the nucleus of that very first cell (called, strangely, a ZYGOTE).
  • Question 9

Pick the word from the list that describes the monthly removal and replacement of the wall of the uterus (generally called a 'period').

CORRECT ANSWER
menstruation
EDDIE SAYS
The wall of the uterus is specially prepared each month for the possible arrival of an embryo (resulting from a fertilised egg) - it's like putting clean sheets on the bed ready for a guest! If the egg is not fertilised (which it rarely is) that special uterine wall is removed (along with the unfertilised egg) during MENSTRUATION - that period of bleeding from the vagina lasts about 5 days.
  • Question 10

Pick the word from the list that describes the monthly release of an egg into the reproductive system.

CORRECT ANSWER
ovulation
EDDIE SAYS
The egg's scientific name is an OVUM, so the term describing its monthly release is OVULATION. One ovary releases one egg into the oviduct. Generally the ovaries alternate, one releasing an egg one month, the other releasing an egg the next, but sometimes two eggs are released - twins may result!
