Quizplus · Accepted Answer

The physical interaction between the respiratory and the cardiovascular system takes place at the gill filaments in fish. The gill filaments are thin, finger-like projections that contain capillaries, where gas exchange occurs between the oxygen in the water and the blood in the capillaries. This is where the respiratory system and cardiovascular system come in close proximity and exchange gases.
