Blood supply to uterus, ovaries and vagina

A
22
Q

Menses of uterine/menstrual cycle

A

Degeneration of endometrium

Menses

23
Q

A

Restoration of the endometrium

24
Q

A
27
Q

What are the different positions the uterus can be in in relation to the bladder

A
28
Q

What sort of epithelium lines the vagina

A

Stratified squamous non-keratinised epithelium

29
Q

How is the vagina different from the oesophagus in terms of its epithelium
