Emphysema results when the delicate linings of the air sacs in the lungs become damaged beyond repair. Most commonly, the toxins in cigarette smoke create the damage. The lung changes of emphysema evolve slowly over years: 1  As the fragile tissues between air sacs are destroyed, air pockets in the lungs develop. 2  Air becomes trapped in these spaces of damaged lung tissue. 3  The lungs slowly enlarge, and breathing requires more effort.
Heart Failure: What Happens to the Body. Every part of your body needs oxygen. Your lungs take in oxygen when you breathe. It is the heartâs job to pump blood to the lungs to pick up oxygen, and then to pump this blood to every part of your body. The heart has two independent pumping systems, one on the right side and one on the left side. Each of these systems has 2 chambers: An atrium (pronounced AY-tree-um).
