Lungs

The lungs are a part of the respiratory system they are soft and spongy and cone shaped, they are two separated sacs or bags which take in air when you inhale, alveoli's are small sacs located in the lungs there are millions of them, and they take in oxygen and remove carbon dioxide when you breathe. Lungs decrease in size when you exhale because the diaphragm flattens and when you inhale the diaphragm contracts which gives more space for the lungs to expand as they fill up with air.

Smoking can give you lung cancer, makes you lose your sense of smell, heart disease, shortness of breath known as emphysema, stomach cancer, mouth and throat cancer, stained teeth and bad breath, and more coughs and colds.

Asthma

Asthma is a common condition in the lungs; people who have asthma can experience coughing, shortness of breath, and tightness in the chest. People who have asthma get asthma attacks because of impure or unclean air which makes there trachea swell and that makes breathing harder so they use their inhalers to expand the trachea to breath easily, attacks can also be triggered by exercise, food allergies, weather, or even emotions sometimes.
