vesicular bronchial and bronchovesicular sounds

In biology, vesicular structures refer to small sacs enclosed by lipid bilayers within cells, essential for transporting and storing substances. They are integral in processes like exocytosis and endocytosis, helping maintain cellular homeostasis and facilitating intercellular communication. These structures are being explored for innovations in drug delivery systems and understanding disease mechanisms, particularly in neurological disorders. In geology, vesicular formations in volcanic rocks provide insights into past volcanic activities, aiding in resource extraction and predicting future eruptions.
