Shrinking and relaxation of scrotum respectively is due to _____?
Increased Temperate & decreased temperature
Decreased temperature & Increased temperature
Increased Temperate & Increased temperature
Decreased temperature & Decreased temperature
Scrotum maintains the temperature of testes 2- 3 degree Celsius below the the body temperature.
When the temperature of the testes falls the scrotum shrinks bringing scrotum close to the body to attain the desired temperature.
When the temperature raises the scrotum is relaxed and the testes comes down at a distance from the body.
Hence option B is correct.
