Question

the dog is placed in a warmer environment, how will its body respond? dogs also have to do cellular respiration. what waste products do they give off. what would happen to the dog if it drank a bunch of saltwater? explain how its body would respond and why. as a dog carries out more exercise but is not consuming more food, how would its body regulate blood glucose levels?

Explanation:

1. When in a warmer environment, a dog may pant to increase heat loss through evaporation from the respiratory tract and may also dilate blood vessels near the skin surface to radiate heat.
2. In cellular respiration, dogs, like other aerobic - organisms, produce carbon dioxide and water as waste products.
3. If a dog drinks saltwater, the high salt concentration will cause water to move out of its cells into the bloodstream due to osmosis. The dog's kidneys will try to excrete the excess salt, but may become over - worked, and the dog may become dehydrated as it loses more water in the process of trying to balance the salt levels.
4. When a dog exercises more without consuming more food, its body will break down glycogen stored in the liver and muscles into glucose to maintain blood glucose levels. The hormone glucagon will stimulate glycogenolysis in the liver, and the body may also start to break down fat for energy to spare glucose for the brain and red blood cells.

Answer:

1. Pant and dilate blood vessels near skin.
2. Carbon dioxide and water.
3. Dehydration as kidneys over - work to excrete excess salt due to osmosis.
4. Break down glycogen into glucose and use fat for energy.
