Quizplus · Accepted Answer

The physical interaction between the respiratory and cardiovascular systems in both humans and fish occurs at the capillaries. In humans, this interaction happens in the lungs where oxygen is exchanged for carbon dioxide. In fish, this exchange occurs in the gills. Capillaries are the site of gas exchange, facilitating the transfer of oxygen into the blood and carbon dioxide out of it.
