structure if female reproductive system

ovary

produces eggs and femake hormones

the fallopian tube (oviduct)

muscular, have funnels at tips to catch the egg after it is released, egg moved along by cilia and muscular peristalsis

uterus

inner lining called endometrium, holds foetus, forms placenta, implantation

vaguna

cervix

opening in the uterus

female hormones

oestrogen and progesterone are produced in ovaries, combination of bith hormones causes secondary female characteristics

secondary female characteristics

maturing + enlargement of breasts widening of pelvis

female infertility

endocrine gland failure - eggs can’t be produces if too little FSH is produced, and fertilisation can’t happen if too little LH

treatment

hormone supplements, IVF

role of meiosis in sperm and egg production

sex cell divides by meiosis, each sperm and egg has 23 chromosomes, as both a sperm nucleus and an egg nucleus are haploid they combine in fertilisation to firm á diploid zygote, the zygote grows by mitosis division ensuring each new cell has a diploid number of chromosomes
