Why is double circulation considered more effective than single circulation?

Answer and explanation

Correct answer: It provides separate routes and suitable pressure for circulation to the lungs and the body

In double circulation, blood passes through the heart between its trip to the lungs and its trip to the body. This keeps the routes separate and allows blood to be sent to the lungs at lower pressure and to the body at higher pressure, supporting effective oxygen delivery.
