When you breathe in, you inhale oxygen into your lungs. Your lung has a left side and a right side. Blood vessels called “capillaries” transfer the oxygen into your blood. Your heart then pumps the oxygen rich blood back to your left atrium.

 

The best place to listen to your lungs is on the side of your chest, just under your arm pit or on your back, just below your shoulder blades. Take a deep breath in , then blow it out. You may also still hear your heartbeat. Your lungs will make a “whooshing sound”, like the wind, when you breathe in and out. Try coughing! The sound of your cough will be louder.
