उत्तर
The female accessory ducts include the fallopian tubes, uterus, and vagina.
- Fallopian Tubes (Oviducts):
- Egg Capture: Finger-like projections called fimbriae sweep over the ovary to capture the released ovum after ovulation.
- Site of Fertilization: The ampulla (the widest part of the tube) is the most common site where sperm and egg meet.
- Transport: Ciliated epithelium and muscular contractions move the ovum or zygote toward the uterus.
- Uterus (Womb):
- Implantation: Provides a site for the fertilized egg (blastocyst) to attach to the endometrium.
- Fetal Development: Expands significantly to house and nourish the growing fetus throughout pregnancy.
- Labor: The muscular myometrium layer contracts powerfully to push the baby out during childbirth.
- Vagina:
- Copulation: Acts as the receptacle for the penis and sperm during intercourse.
- Birth Canal: Serves as the passageway for the baby to exit the body during delivery.
- Menstruation: Provides a channel for menstrual blood and tissue to leave the body.
