True
Epididymis

Infundibulum
Catches the ova when it is ovulated, location sperm storage, and fertilization.
Magnum
Secretes the albumen protein (egg white)
Isthmus
The two shell membranes are deposited
Uterus
Plumping, the taking up of water, occurs; eggshell and shell pigment deposited
Vagina
Rotates the egg from pointed and down to round and down.
the phases of follicular growth are
- slow growth lasts months to years; this phase is little growth
- the size of the yolk begins to increase in size from growth of yolk protein
- rapid growth occurs 6-11 days before ovulation
utero-vaginal juncture
provides a storage area for sperm after copulation until oviposition occurs
