Final answer:
The male urethra and pancreas belong to more than one organ system, serving functions in both the urinary and reproductive systems for the urethra, and the digestive and endocrine systems for the pancreas.
Step-by-step explanation:
The organs that belong to more than one organ system in the given options are the male urethra and the pancreas.
The male urethra is part of both the urinary system, as it carries urine from the bladder during urination, and the reproductive system, as it transports sperm during ejaculation. Thus, it is the part of the male urogenital tract that is shared by both systems. On the other hand, the pancreas is part of the digestive system through its role in secreting digestive enzymes into the small intestine and part of the endocrine system through its function in releasing insulin and glucagon into the bloodstream.
Organs such as the testes and ovaries are primarily associated with the reproductive system. Although they do have additional functions, such as hormone production, within the context of this question, they are considered part of only the reproductive system.
