Figure 1

Elastic fiber layers. (a) Negative control (K0) with an average number of elastic fiber layers of 10.3. (b) Moderate-intensity aerobic physical exercise (K1) with an average number of elastic fiber layers of 9.5. (c) Exposure to electronic cigarettes (K2) with an average number of elastic fiber layers of 9.0. (d). The combination of exposure to electronic cigarettes and moderate-intensity aerobic physical exercise (K3) showed an average number of elastic fiber layers of 8.7 (H&E), 40x.
