Answer 1

The human respiratory system is a complex network of organs and tissues that help in the process of respiration. It includes the lungs, bronchial tubes, trachea, nose, and mouth. The primary function of the respiratory system is to exchange oxygen and carbon dioxide between the body and the environment, allowing for the intake of oxygen and the removal of carbon dioxide waste. Additionally, it helps regulate the pH levels in the body and plays a role in vocalization.
