Pulmonary fibrosis replaces normal lung cells with fibrous tissue, impairing gas exchange and causing breathing inefficiency.
Pulmonary fibrosis is a condition where fibrous tissue replaces normal lung epithelial cells, leading to decreased gas exchange in the lungs. This results in inefficient breathing and decreased oxygen levels in the body, impacting overall respiratory function. The individual's lungs do not replace connective tissue with epithelial tissue, and the inflammation affects the gas exchange process, not the heart directly.
