What is septa in lungs?

Septa in lungs are thin walls made up of connective tissue and elastic fibers. They divide the lungs into small sections called lobules, which contain bronchioles, alveolar ducts, and alveoli. The septa in the lungs act as a barrier that prevents the spread of infections and injuries from one part of the lung to another. They also help in maintaining the structural integrity of the lungs and provide support for gas exchange during breathing. Damage or scarring to the septa can lead to respiratory problems such as shortness of breath, coughing, and wheezing. Diseases such as pneumonia, emphysema, and pulmonary fibrosis can cause damage to the septa in the lungs.
