7b: Reproduction

Ovaries
1. release eggs
2. make eggs
3. are where a foetus grows
4. are next to the cervix
Fertilisation happens in the
1. fallopian tube
2. uterus
3. ovary
4. cervix
The placenta
1. allows the foetus to get nutrients and oxygen
2. is a cord that joins to the foetus' navel
3. is a fluid surrounding the foetus
4. is a membrane enclosing the foetus
Gestation is
1. the time from conception to birth
2. breaking down food so it can be absorbed into the bloodstream
3. a process that takes in carbon dioxide
4. when a baby is not yet ready for solid foods
Hormones are
1. chemicals that help to control processes in your body
2. finger-like structures on the intestine wall
3. electrical signals in your brain
4. not present in plants
the egg tube is also called the
1. fallopian tube
2. ovary
3. cervix
4. yolk tube
Testes
1. make sperm
2. release eggs
3. add fluids to the sperm to make semen
4. connect the ovaries to the uterus
The womb is also called
1. the uterus
2. the ovary
3. the cervix
4. the oviduct
The cervix
1. is the neck of the uterus
2. releases eggs
3. produces sperm
4. carries eggs to the uterus
fertilisation is
1. when a sperm joins with an egg
2. when sperms are released
3. when eggs are released
4. when an egg implants in the uterus
The fertilised egg implants in
1. the wall of the uterus
2. the ovary
3. the testes
4. the sperm tube
the placenta
1. acts as a barrier between the mother and the baby's blood
2. is where the fertilised egg develops
3. releases eggs
4. is where fertilisation occurs
The umbilical cord
1. connects the placenta to the foetus
2. connects the testes to the penis
3. connects the ovary to the uterus
4. passes oxygen from the foetus to the mother
The umbilical cord
1. passes oxygen to the foetus
2. passes oxygen to the mother
3. passes carbon dioxide to the foetus
4. passes carbon dioxide from the mother
the umbilical cord
1. passes nutrients to the foetus
2. passes nutrients from the foetus
3. passes nutrients to the mother
4. passes oxygen from the foetus to the mother
amniotic fluid
1. surrounds the foetus, for protection
2. nourishes the sperm, to help them swim
3. triggers the release of eggs
4. is a hormone
a human baby is usually born
1. head first
2. feet first
3. ten months after fertilisation
4. 20 weeks after fertilisation
The testes are on the outside of the body because
1. sperm needs to be stored below body temperature
2. sperm needs to be stored above body temperature
3. sperm cannot be produced at body temperature
4. to keep the sperm away from the glands until needed
How many sperm cells will enter the egg?
1. one
2. two
3. 1 million
4. 500 million
the egg is one of the largest cells in the body because
1. it has lots of cytoplasm to nourish it until it implants
2. it must be easy for sperm to find
3. it contains more genetic information than other cells
4. the nucleus is larger
the placenta
1. is also called the "afterbirth"
2. comes out of the vagina before the baby is born
3. contains few blood vessels
4. connects the baby's blood system directly to the mother's
a baby in the uterus
1. gets food and oxygen through the umbilical cord
2. gets carbon dioxide through the umbilical cord
3. cannot move at all
4. is usually observed using x-rays
a typical menstrual cycle lasts
1. 28 days
2. 14 days
3. 5 days
4. 3 days
a typical period lasts
1. 5 days
2. 28 days
3. 14 days
4. 2 days
on which day of the menstrual cycle is an egg usually released?
1. day 14
2. day 1
3. day 21
4. day 7
around which time of the menstrual cycle is a woman most fertile?
1. day 14
2. day 1
3. day 21
4. day 7
the egg tube is also called the
1. oviduct
2. ovary
3. cervix
4. yolk tube
the human gestation period is
1. 40 weeks from the last period
2. 30 weeks from the last period
3. 50 weeks from the last period
4. 20 weeks from the last period
the foetus grows in the
1. uterus
2. ovary
3. cervix
4. vagina
semen is
1. sperms plus fluids to make them swim
2. fluids to make sperm swim
3. sperm
4. sperm and urine
