THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Seminal fluid, or semen, is a slightly alkaline mixture of sperm cells and secretions from the accessory glands . Secretions from the seminal vesicles make up about 60 percent of the volume of the semen, with most of the remainder coming from the prostate gland.

Detailed explanation-2: -The sperm arrive first at the ampulla just above the prostate gland. Here, secretions from the seminal vesicle located next to the ampulla are added. Next, the seminal fluid is propelled forward through the ejaculatory ducts toward the urethra. As it passes the prostate gland, a milky fluid is added to make semen.
