Short answer: I can't put a picture into the chat, but here is a correct labelled scheme of the system plus the order in which to draw it on paper — it's the same on any sheet.

                    ┌──────────────┐          ┌──────────────┐
                    │  OVARY  (1)  │          │  OVARY  (1)  │
                    └──────┬───────┘          └──────┬───────┘
                           │                         │
                    ┌──────┴───────┐          ┌──────┴───────┐
                    │ OVIDUCT (2)  │          │  OVIDUCT (2) │
                    └──────┬───────┘          └──────┬───────┘
                           └────────────┬────────────┘
                                        │
                              ┌─────────┴──────────┐
                              │     UTERUS (3)     │
                              │       (womb)       │
                              └─────────┬──────────┘
                                        │
                              ┌─────────┴──────────┐
                              │      CERVIX (4)    │

                                        │
                              ┌─────────┴──────────┐
                              │      VAGINA (5)    │
                              └────────────────────┘

How to build the drawing step by step

  1. Axis first. Draw a light vertical midline — the whole system is symmetrical, and this line keeps the uterus, cervix and vagina in a row.
  2. Uterus (3). An upside-down pear: a broad rounded top (fundus) about 5 cm wide, narrowing downwards, total about 7 × 5 × 2.5 cm. It sits in the middle, tilted slightly forward.
  3. Cervix (4). A short cylinder about 2.5 cm long under the uterus; its lower part bulges into the top of the vagina.
  4. Vagina (5). A flattened muscular canal 7–8 cm long going down from the cervix; draw two slightly wavy lines to suggest the folds (rugae).
  5. Oviducts / fallopian tubes (2). Two curved tubes about 10 cm, leaving the upper corners of the uterus, arching up and outward, then bending down. At the free end draw the fimbriae — a small fringe of finger-like projections.
  6. Ovaries (1). Two almond-shaped bodies about 3 × 2 × 1.5 cm, one on each side, placed just below and behind the fimbriae. They are not fused to the tube — keep a small gap and add the ovarian ligament.
  7. Labels. Straight horizontal lines to the right of the drawing, no crossing lines, full names: ovary, oviduct (fallopian tube), uterus, cervix, vagina.

Why it looks like this (so you can reason, not memorise)

Part Position in the scheme Job
Ovary lateral, paired produces oocytes and hormones
Oviduct between ovary and uterus carries the oocyte; fertilisation happens here
Uterus central, pear-shaped implantation and development of the embryo
Cervix between uterus and vagina gateway, produces mucus
Vagina lowest copulation and birth canal

The path of the egg runs ovary → fimbriae → oviduct → uterus, so the parts are drawn in that order from the outside inwards.

Check your result

  • two ovaries and two oviducts, mirror-symmetric about the midline;
  • uterus pear-shaped with a rounded fundus on top, not a straight tube;
  • fimbriae present and not touching the ovary;
  • cervix present between uterus and vagina;
  • all five labels, spelled correctly.

If the teacher asks for a sagittal section, add the bladder in front of the uterus, the rectum behind it, and the pubic symphysis at the front.
