Answer 2

Answer:

Explanation:

Seminal vesicle: It is formed from the Wolffian duct of the embryo. Internally it is lined by glandular epithelium which secretes seminal fluid. This is lubricating , transparent and jelly like substance, which makes 60-70% part of semen. It is slightly alkaline 9pH 7.3). Fructose is found in seminal fluid, it act as fule to sperm.

Prostate glands: Prostate gland secrete slightly alkaline prostatic fluid which is milky, thick, sticky or jelly like. It makes about 30% part of semen and helps in sperm activation. The secretion of prostate glands has citric acid, calcium and phosphate, clotting enzyme and profibrinolysin are present. The secretion of the prostate gland combined with the secretion of seminal vesicle and so the semen gets coagulated
