RESPIRATORY SYSTEM

Abstract

The respiratory system is one of the most important systems in the human body. It ensures the exchange of gases between the body and the external environment. This system provides oxygen for cellular metabolism and removes carbon dioxide, which is a waste product. The respiratory organs include the nose, trachea, bronchi, and lungs, where gas exchange takes place in tiny structures called alveoli. This paper explores the structure, function, and importance of the respiratory system, as well as common diseases and preventive measures to maintain respiratory health.
