What do you call the structure of the arteries and veins in a penguin’s legs?
- convective heat exchange
- Wonder Net
- Radiant cooling system
See the answer
Wonder Net
The veins in a penguin’s legs surround the arteries, a structure known as the rete mirabile (wonder net). When feet rest on cold ground, blood vessels normally constrict to conserve body heat, which, if prolonged, leads to poor circulation and can cause chilblains or frostbite. However, in penguins, the veins carrying cooled blood from the feet encircle the arteries, cooling the arterial blood in turn. As a result, the vessels no longer need to constrict, eliminating the risk of chilblains and frostbite.
Which kanji is used to write “penguin?”

penguin
Penguins are sometimes written in kanji as “人鳥” (human bird). One theory holds that this is because they cannot fly and walk upright on land in a straight, human-like posture. Although it wasn’t among the options, they can also be written as “企鵝.” Here, “企” means standing on tiptoes, and “鵝” refers to a goose; these characters were applied based on the penguin’s way of walking and appearance.
