Human Reproductive System, Charts, School Education

Quick Answer: A human reproductive system chart is a labelled biology wall chart showing the male and female reproductive organs and, usually, how fertilisation leads to the development of an embryo. Secondary schools use it to teach human reproduction clearly, with the correct scientific names.

Organs, Gametes and Fertilisation in Labelled Diagrams

The male half of a human reproductive system chart normally shows the testes held in the scrotum, where sperm are produced, the epididymis where they mature and are stored, the vas deferens (sperm duct), the seminal vesicles and prostate gland that add fluid, and the urethra. The female half shows the paired ovaries that release an egg (ovum), the fallopian tubes or oviducts, the uterus with its muscular wall and inner lining, the cervix and the vagina.

Sequence panels usually follow on from the organ diagrams. They trace fertilisation in the fallopian tube, the zygote dividing as it moves down to the uterus, implantation in the uterine lining, and the embryo connected to the placenta by the umbilical cord. Many sets also add the menstrual cycle, drawn as a timeline of the lining building up and then breaking down.

Clear sectional drawings help take awkwardness out of the topic. A teacher can point to each organ, use its proper name and move the discussion on to function, which is also how the chapter is examined.

Applications

• Teaching the human reproduction chapter in secondary biology with correct terminology
• Showing where fertilisation and implantation take place before a lesson on pregnancy and birth
• Adolescence education sessions led by a biology teacher or school counsellor
• Diagram-labelling practice for board examinations

Specifications

Care & Handling

• Put the human reproductive system chart up in the biology room for the duration of the unit, rather than permanently in a corridor, so it is always introduced with an explanation.
• A clip rail lets the teacher take the sheet down at the end of the lesson and rehang it quickly for revision.
• Keep a spare copy in the department store so a scribbled-on sheet can be swapped without interrupting the unit.

Why Choose LabEquip

Biology teachers usually order this chart with other human body titles such as the Human Physiology Charts, and some add a torso or organ model from the anatomy models range. Send class levels and quantities through the LabEquip contact page.

Frequently Asked Questions

Where does fertilisation take place in humans?

Usually in the fallopian tube (oviduct). A sperm fuses with the egg to form a zygote, which divides repeatedly as it travels to the uterus over several days before implanting in the uterine lining.

What is the function of the placenta?

The placenta links the developing embryo to the wall of the uterus. It passes oxygen and nutrients from the mother’s blood to the embryo and removes carbon dioxide and wastes, without the two blood supplies mixing.

Why are the testes outside the abdomen?

Sperm are produced most efficiently at a temperature slightly below normal body temperature. The scrotum holds the testes outside the abdominal cavity, where they stay a little cooler.

What happens during the menstrual cycle?

About once a month an ovary releases an egg and the uterine lining thickens to receive it. If fertilisation does not happen, the lining breaks down and leaves the body as menstruation, and the cycle starts again. A cycle typically lasts about 28 days, though it varies.

How many chromosomes do human gametes carry?

Sperm and egg are haploid, each with 23 chromosomes. Fertilisation restores the full 46 chromosomes (23 pairs) in the zygote, including the sex chromosomes: an egg always carries X, and the sperm carries X or Y, which decides the sex of the child.

Which classes use this chart?

It supports the reproduction chapters of secondary and senior secondary biology. It is also useful in adolescence education sessions, where a teacher wants accurate diagrams and the correct name for each organ.
