Q

When you ovulate, what is created?

A

Corpus Luteum

17
Q

What does the Corpus Luteum produce?

A

Progesterone

18
Q

Where does the Corpus Luteum form?

A

In the ovulated follicle.

19
Q

As the empty follicle that the egg came out of begins to shrink, and the egg is not fertilized, what happens?

A

A decrease in estrogen and progesterone, which means the thick womb lining breaks down and comes out as blood, starting your period.

20
Q

What’s a zygote?

A

fertilized egg

21
Q

What is anisogamy?

A

Where the gametes come from two different individuals

22
Q

Advantages of sexual reproduction?

A

Creates a organism which has different genes

23
Q

Disadvantages of sexual reproduction?

A

Requires two parents, genetic variation, more energy, less offspring.

24
Q

What are the advantages of asexual reproduction?

A

One parent needed, rapid population growth, low resource investment.

25
Q

What is binary fission?

A

A form of asexual reproduction in which the parent divides into two parts.

26
Q

What is parthenogenesis?

A

Where an unfertilized egg develops.

27
Q

What are all the types of asexual reproduction?

A

Binary fission, budding, vegetative propagation, sporogenesis, fragmentation, parthenogenesis

28
Q

What happens in the first trimester of pregnancy?

A

Outer layer of the embryo merges with the endometrium and the placenta forms.

29
Q

What happens in the second trimester of pregnancy?

A

Placenta takes over functions from the corpus luteum.

30
Q

What happens in the third trimester?

A

The fetus growth accelerates.

31
Q

What is IVF?

A

Artificial fertilization of a human egg.

32
Q

What is gestation?

A

The development period between the fertilization of the egg and birth.

33
Q

What is the function of the Cowper’s gland?

A

To release a fluid that reduces the acidity of the female reproductive system for sperm travelling. It is located at the base of the penis in a series of small glands.

34
Q

What does the hypothalamus do and where is it located?

A

It’s a gland located at the bottom of the brain that releases GnRH to stimulate the anterior pituitary gland.

35
Q

What are the pituitary glands, what do they produce and what are they powered by?

A

The anterior pituitary glands are glands that are located underneath the hypothalamus. The hypothalamus creates GnRH to power the anterior pituitary gland, which in turn produces LH and FSH for different organs.

36
Q

What is Estrogen processed by and what is its function?

A

Estrogen is a female sex hormone produced by the ovaries (mainly) and controls physical and some emotional development. e.g. Breast development, pubic hair etc.

37
Q

What does progesterone do?
