TEASE YOU BRAIN Write the numbers 1 to 7, one in each circle, so that the sum of the three circles along each straight line equals 12. YOU CAN DO IT Explain This! During a heat wave last August in northern Italy, this pigeon was spotted dunking its head under the cool water flowing from a fountain in Catena ca·te·na n. pl. ca·te·nae or ca·te·nas A closely linked series, especially of excerpted writings or commentaries. [Latin cat Square in Riva Del Garda. The pigeon was likely trying to prevent its body from overheating Overheating An economy that is growing very quickly, with the risk of high inflation. . Unlike humans, birds don't have sweat glands, which secrete sweat that is mostly made of water. As the water in sweat evaporates, it helps wick heat away from the human body. Instead of sweat glands, birds have air sacs air sacs sacs that communicate with the respiratory, air-filled membranous system in birds and primates. avian air sacs there are eight air sacs in the chicken: an unpaired cervical, an unpaired clavicular, a pair of cranial to regulate their body temperature When a bird feels hot, it starts panting panting rapid, shallow breathing, a characteristic heat-losing reaction in dogs; represents an increase in dead-space ventilation resulting in heat loss without necessarily increasing oxygen uptake or carbon dioxide loss. . By quickly breathing in and out, the bird causes water to evaporate from its air sacs As the water becomes a gas, the vapor carries heat away from the bird's body, helping to lower the bird's body temperature. But sometimes this method isn't enough to cool the bird, so it takes a refreshing dip in cool water. |
