The mechanisms for breathing are significantly compromised in Anthony’s case, which is suffering from emphysema since he has abnormal enlargement of air spaces distal to the terminal bronchioles (Grossman & Porth, 2014). This led to the destruction of Anthony’s alveolar walls. This, in turn, has reduces gas exchange and air path dynamics that have impaired Anthony’s expiratory airflow and progressive air trapping, thus difficulty in breathing. Additionally, Anthony’s compromised breathing is a result of static hyperinflation caused by a decrease in lung elasticity. The lungs exert less recoil pressure to encounter the recoil pressure in Anthony’s chest wall, creating an equilibrium of recoil forces at a higher resting volume than normal

The mechanisms of breathing are significantly compromised in Tabitha’s case who suffers from infant respiratory distress syndrome since she lacks enough surfactant in her lungs, a liquid produced by the lungs that help keep the alveoli open; this makes it difficult for her an infant to breathe in the air after her delivery. Because Tabitha lacks enough surfactant, her tiny alveoli collapse with every breath. The collapse in the alveoli allows damaged cells to collect in her airways, which further affects her breathing ability. Her breathing is compromised as she tries harder to reinflate her collapsed airways.

The mechanisms of breathing are significantly compromised in Jenny’s case, who suffers from pulmonary fibrosis because the scarring affects the air sacs in Jenny’s lungs. The scarring makes his lungs unable to expand to allow him to take deep breaths, and the level of oxygen in his blood drops (Grossman & Porth, 2014). The pulmonary fibrosis stiffens his lungs, reducing his lung capacity and size. This makes him feel breathing is hard work and feel breathless from physical activities such as walking and running, and this is because the condition has affected his lungs.
