Why is countercurrent flow more efficient for gas exchange? - TimesMojo

GlobePedia on Instagram: "A duck may use its own body heat to defrost its beak when it gets cold or covered with ice. Ducks' unique blood artery system, known as countercurrent heat exchange, aids in controlling the temperature of their extremities, such as the feet and beak.
