B) warmer venous blood transfers heat to the cooler arterial blood 
C) warmer arterial blood transfers heat to the cooler venous blood 
D) arterial blood is always cooler in the abdomen, compared to the temperature of the venous blood in the feet of the goose

Quizplus · Accepted Answer

The thin horizontal arrows show that warmer arterial blood transfers heat to the cooler venous blood. This helps to conserve body heat in the colder environment. Option A is incorrect as it suggests that warm arterial blood can bypass the legs when they are too cold to function well, which is not supported by the figure. Option B is also incorrect as there is no indication in the figure that warmer venous blood transfers heat to cooler arterial blood. Option D is incorrect as there is no information in the figure about the relative temperatures of arterial blood in the abdomen and venous blood in the feet of the goose.
