What is empheseyma?

Answer 1

Emphysema is a lung condition in which tiny air sacs in the lungs - alveoli - fill up with air. As the air continues to build up in these sacs, they expand, and may break or become damaged and form scar tissue.

Answer 2

Emphysema is a disease where the alveoli in the lungs basically have holes in them and don't hold oxygen well. It is hard to breathe with emphysema.
