Real-life examples of animals breathing air to survive

📚 Quick Study Guide

• 🫁 Air Breathing: Many animals have evolved to breathe air directly, rather than extracting oxygen from water.
• 🐟 Fish: Some fish, like the lungfish, have lungs and can breathe air when water oxygen levels are low.
• 🐸 Amphibians: Frogs use their skin for some gas exchange but also have lungs for air breathing.
• 🐍 Reptiles: Reptiles, such as snakes and lizards, rely entirely on lungs for breathing air.
• 🐦 Birds: Birds have a unique respiratory system with air sacs that allow for efficient oxygen uptake during flight.
• mammals Mammals: Mammals, including humans, use lungs to breathe air, extracting oxygen and expelling carbon dioxide.
• 🐳 Aquatic Mammals: Whales and dolphins are mammals that must surface to breathe air using their lungs.
