Answer 1

The human respiratory system is responsible for the exchange of gases between the body and the environment, primarily facilitating the intake of oxygen and the expulsion of carbon dioxide. Key organs in this system include the lungs, which house the alveoli where gas exchange occurs; the trachea, which serves as the windpipe connecting the throat to the lungs; and the diaphragm, a muscle that aids in the inhalation and exhalation process by contracting and relaxing to change the volume of the thoracic cavity. This intricate system supports cellular respiration, providing essential oxygen for metabolic processes and removing metabolic waste in the form of carbon dioxide.
