Breathing

Breathing notes

QuestionAnswer
What happens when you breathe? Goes through the mouth, larynx, trachea, bronchi, then your lungs. You breathe in oxygen, and lungs exchange it for carbon dioxide. Diaphragm contracts when breathing, and relaxes when no air.
Lungs It weighs 2 pounds when it's full of air and is pale pink when healthy.
Bronchi Lungs have 600 million bronchioles in them. Alveoli cluster around the end on bronchioles, and soak up oxygen like a sponge.
Aveolus Tiny air sacs called alveoli where oxygen enters carbon dioxide and leaves blood.
Trachea Voice box vibrates when you swallow. When you breathe, epiglottis opens and cartilage protects trachea.
Diaphragm When chest fills with air, diaphragm expands. Ribs relax when air is out of your body.
