Category: Male Reproductive System

This illustration activity shows a detailed anatomical diagram of the male reproductive system from a lateral viewpoint. The diagram highlights the location of key components from top of the diagram is the ureter. Then from right to left is the urinary bladder followed by the seminal vesicles which are a pair of glands that secrete fluid making up a substantial portion of seminal fluid. The pubic bone is one of the three bones making up the pelvis. The vas deferens is a carrying vessel that transports sperm from the testes to the urethra. Located at the base of the bladder is prostate gland, this gland secretes nourishing fluid for sperm and becomes a component of semen. The urethra extends from the urinary bladder and carries the semen towards the penis. The penis, the external male sex organ used to inseminate a female during reproduction. The rectum is the straight portion of the lower large intestines, and the anus expels fecal matter. Located under the penis is the testes and extending from the testes is a cordlike structure known as the epididymis.
