Final answer:
The statement is true; the cloaca is a common body opening in many non-mammalian vertebrates for the digestive, excretory, and reproductive systems.
Step-by-step explanation:
The statement that the cloaca receives products from the urinary and reproductive systems, as well as the urogenital system, is True. In many non-mammalian vertebrates, such as birds and reptiles, the cloaca is a common body opening that serves as an exit for the digestive and excretory systems, which includes urine waste, and for the reproductive system, through which gametes are released. The presence of a cloaca is a significant difference from the anatomy of mammals, who typically have separate openings for these systems.
