Study Notes
Why Dogs Pant
- Dogs pant to prevent overheating.
- When a dog breathes in, it takes in cool outside air, and when it breathes out, it expels hot air because the air equilibrates with its body temperature.
- This process allows the dog to expel heat every time it breathes.
Importance of Panting for Dogs
- Dogs can't sweat due to their fur coats, so panting is their primary method of losing heat.
- Panting is crucial for dogs because it helps them regulate their body temperature.
Human Respiration and Heat Loss
- Humans can sweat to lose heat, but they also lose heat through respiration.
- When humans breathe in, the air equilibrates with the temperature of the blood in the alveoli, and when they breathe out, they expel air that's close to body temperature (around 98.6°F).
- This process is an example of thermoregulation, which means regulating body temperature.
Exercise and Respiration
- During exercise, humans need more oxygen to feed their muscles and also need to get rid of excess heat.
- Breathing heavily during exercise provides more oxygen and also expels more heat, making it a convenient process.
- At rest, humans breathe around 5 liters of air per minute, but during heavy exercise, this can increase to 50 liters per minute.
