What is the difference in function of the secretions of seminal vesicle and bulbo urethralgland?

Dear student, The main function of seminal vesicles is to secrete a significant proportion of the fluid which ultimately gets converted into semen. On the other hand bulbourethral gland secreate a clear fluid which is rich in mucoproteins that help to lubricate the urethra only and contains a very little quantity of semen. Regards
