Respiratory System

Breathing what your body does when it takes in fresh air, containing oxygen, and lets out the used air.
Respiratory System the body parts that work together to bring air into and push it out of your body.
Nose and Mouth take in and let out air
Windpipe/Trachea the air passage connecting the throat to the lungs
Lungs two spongy bags that expand when they fill with air
Diaphragm a dome-shaped muscle that separates the chest from the stomach area. When you inhale, the diaphragm tightens & moves down, further increasing the space inside the chest. When you exhale, the diaphragm relaxes & moves up, making less space inside the chest
Cartilage tough but bendable material. cartilage makes your windpipe stiff, so your windpipe doesn't collapse when you breathe in
Inhale when you breathe in and your lungs fill with air
Exhale when you breathe out and air is forced out of your lungs
Breathing Rate the number of times you inhale in one minute
Larynx also known as the voice box, it is at the top of the windpipe, all the air you breathe passes through it
Vocal Cords two elastic bands inside the larynx. To make high-pitched sounds, you tighten your vocal cords. Then they vibrate faster as air goes past. To make low-pitched sounds you relax your vocal cords.
Bronchial Tubes when you inhale, air moves from the windpipe into the two bronchial tubes, one going to each lung.
