Review unit 3: Reproduction

The [blank_start]ovaries[blank_end] produce female reproductive cells called [blank_start]ova[blank_end]. One [blank_start]ovum[blank_end] matures each month. Women are born with all the ova they will need for the rest of their life. The [blank_start]fallopian[blank_end] tubes connect the ovaries to the [blank_start]uterus[blank_end]. The uterus is an organ with [blank_start]muscular[blank_end] walls. During [blank_start]pregnancy[blank_end] a fertilised cell develops into a [blank_start]baby[blank_end] in the uterus. The part of the uterus that leads to the vagina is called the [blank_start]cervix[blank_end].

Identify the diferent female reproductive organs

Pregnancy last about 42 weeks

Fertilisation occurs in the uterus

After fertilisation ovum divides in multiple cells, which is called zygote

The [blank_start]testicles[blank_end] produce and store sperm. The testicles are located in a bag of skin called the [blank_start]scrotum[blank_end]. The scrotum regulates the [blank_start]temperature[blank_end] of the testicles. They need to be a bit cooler than the rest of the body in order to produce [blank_start]sperm[blank_end].

After about nine [blank_start]weeks[blank_end], all the organs have formed and the embryo develops into a [blank_start]foetus[blank_end]. The foetus floats in a sac of [blank_start]amniotic[blank_end] fluid which protects it from knocks and bumps. The foetus receives oxygen and [blank_start]nourishment[blank_end] from the mother’s [blank_start]placenta[blank_end]. Waste matter and carbon [blank_start]dioxide[blank_end] are transferred from the foetus to the mother via the placenta. The baby is connected to the placenta by the [blank_start]umbilical[blank_end] cord.
