Question

4. Why do testes lie within the scrotum,
outside the body?
5. What is the significance of thick muscular
walls of uterus in females?
​

Answer 1

Answer:

(4.). The testicles make sperm. To do this, the temperature of the testicles needs to be cooler than the inside of the body. This is why the scrotum is located outside of the body.

(5). The uterus is shaped like an upside-down pear, with a thick lining and muscular walls — in fact, the uterus contains some of the strongest muscles in the female body. These muscles are able to expand and contract to accommodate a growing fetus and then help push the baby out during labor.

Answer 2

Answer:

The scrotum lie outside the body ( outside the abdominal cavity ) because the main function of them is to release sperms and sperms need a specific temperature to arise ( except from the body temperature) thus for forming sperms they need less temperature than the body and live outside.
