Prostate gland. Light micrograph of a section through a healthy prostate gland. The prostate is a large male gland that surrounds the neck of the bladder and the urethra, the tube that carries both urine and semen out of the body. Numerous excretory ducts (interlinked tubes) are seen. The prostate produces an alkaline secretion that forms part of the seminal fluid. It also produces secretions that keep the lining of the urethra moist. Brightfield illumination. Magnification: x10 at 35mm size.
