List two functions performed by the testis in human beings.
Official answer
The two primary functions performed by the testes in human beings are:
- Production of male gametes (sperms): The testes produce millions of male germ-cells called sperms.
- Secretion of testosterone: The testes secrete the male sex hormone, testosterone, which regulates the production of sperms and brings about secondary sexual characteristics in boys during puberty.
Marking scheme
- 1.0.5 marks for stating the production of sperms/male gametes.
- 2.0.5 marks for stating the secretion of testosterone/male sex hormone.
Hint
Think about the male gametes produced by the male reproductive system and the hormone responsible for changes during puberty in boys.
Quick oral answer
The two main functions of the testes are the production of male gametes (sperms) and the secretion of the male sex hormone, testosterone.
Common mistakes
- 1.Confusing the function of the testes with other glands like the prostate gland or seminal vesicles.
- 2.Spelling 'testosterone' incorrectly.
Analysis and explanation
The testes are the primary male reproductive organs in humans. They perform both an exocrine function (producing sperms) and an endocrine function (secreting testosterone). Testosterone is crucial for the development of male reproductive tissues and secondary sexual characteristics such as facial hair, deep voice, and muscle growth.
Interesting facts
The testes are located outside the abdominal cavity in the scrotum because sperm formation requires a temperature lower than the normal body temperature.
