Contains a spongy tissue that becomes swollen and upright when filled with blood
What is a scrotum and why are testes located in here?
Scrotum is a pouch of skin formed from the lower part of the abdominal wall.

Hint: It’s a long thick tube
Vas Deferens
What are the three accessory glands??
Seminal vesicular, prospate gland and bulbourethral gland.
What gland provides alkaline mucin and lubricrates urethra?
Bulbourethral gland
What gland produce a sticky yellowish fluid that contain fructose (sugar)?
Seminal vesicle
What gland provides alkaline ph and clotting enzymes?
