Homework Answers
The correct answer for the above statement is b) the internal urethral sphincter constrict.
Ejaculation is process of discharge of semen which normally contain sperm in males .The sperm is passed through various ducts such as epididymis , duct deferens (vas deferens) , ejaculatory duct and urethra before moving outside of the body.
