NCERT lists them as a pair of ovaries, a pair of oviducts (fallopian tubes), the uterus, the cervix, the vagina, and the external genitalia, all in the pelvic region. A pair of mammary glands is also part of the system. The natural path of the egg is: ovary (makes ovum) to oviduct (fertilisation site) to uterus (baby develops) to cervix to vagina (birth canal). Learning this order helps you answer many NEET matching questions.
The ovaries are the primary female sex organs. NCERT says the ovaries produce the female gamete (the ovum) and several steroid hormones called ovarian hormones. All other parts — oviducts, uterus, cervix, vagina, external genitalia and mammary glands — are accessory parts. NEET often asks 'primary vs accessory', so remember: primary = organ that makes the gamete = ovary.
The primary sex organ is the ovary, because it makes the gamete (ovum). The accessory ducts are the oviducts, uterus and vagina — NCERT names exactly these three as the female accessory ducts. Accessory ducts do not make gametes; they carry the ovum, hold the developing baby, or form part of the birth canal. Do not add the cervix or external genitalia to the 'accessory ducts' list in NEET.
Yes. NCERT uses both names for the same structure: 'the oviducts (fallopian tubes)'. Each fallopian tube is about 10–12 cm long and runs from near each ovary to the uterus. It has four regions in order — infundibulum (with finger-like fimbriae), ampulla (wide part where fertilisation happens), and isthmus (narrow part that joins the uterus). NEET can use either word, so treat them as identical.
The cervical canal (the cavity of the cervix) together with the vagina forms the birth canal. The uterus opens into the vagina through a narrow cervix, and the cavity of that cervix is called the cervical canal. This exact line was tested in NEET 2023, so learn it word for word: 'cervical canal along with vagina forms the birth canal'.
Yes. NCERT includes a pair of mammary glands as part of the female reproductive system and calls them a female secondary sexual characteristic. Each breast has 15–20 mammary lobes made of clusters of cells called alveoli, which secrete milk. The alveoli connect through mammary tubules and ducts to a lactiferous duct that opens at the nipple.
Given below are two statements: Statement I: Vas deferens receives a duct from seminal vesicle and opens into urethra as the ejaculatory duct. Statement II: The cavity of the cervix is called cervical canal which along with vagina forms birth canal. In the light of the above statements, choose the correct answer.
Which of the following structures is not a part of the male reproductive system?
Match Column-I with Column-II: a. Mons pubis, b. Antrum, c. Trophectoderm, d. Nebenkern with (i) Embryo formation, (ii) Antrum, (iii) Female external genitalia, (iv) Graafian follicle.
Try the real previous-year questions from this chapter — each with the answer and a full solution.
There is one pair of each — two ovaries and two oviducts (fallopian tubes). The uterus, cervix and vagina are single structures, and there is also one pair of mammary glands.
Fertilisation takes place in the ampulla, the wide part of the oviduct. The ovum and sperms must reach the ampullary region at the same time for fusion to occur.
From the ovary to the uterus: infundibulum (with fimbriae), then ampulla (the wide part), then isthmus (the narrow part that joins the uterus). Memory: Fimbriae-Infundibulum, Ampulla, Isthmus — 'catch, fuse, pass'.
NCERT lists mons pubis, labia majora, labia minora, hymen and clitoris. The clitoris lies at the upper junction of the two labia minora, above the urethral opening.
The uterus (womb) is shaped like an inverted pear. Its wall has three layers: the outer thin perimetrium, the middle thick muscle layer myometrium, and the inner glandular endometrium that lines the uterine cavity.
