Final answer:
The correct order of air passage through the respiratory system during inhalation is nose, pharynx, larynx, trachea, and bronchi, leading down to the smaller bronchioles and the alveoli where gas exchange occurs.
Step-by-step explanation:
The correct sequence that describes the path that air travels through the respiratory system is: nose, pharynx, larynx, trachea, and bronchi. When we inhale air, it first enters through the nose, where it is filtered, warmed, and moistened. The air then passes through the pharynx, a muscular tube that serves both the respiratory and digestive systems. Next, air moves through the larynx, which houses the vocal cords, before entering the trachea or windpipe. The trachea then bifurcates into the left and right bronchi as it reaches the lungs. These pathways further divide into smaller tubes called bronchioles, which eventually lead to tiny air sacs known as alveoli, where gas exchange occurs.
During breathing, inhaled air enters the body through the nose and passes through the pharynx, larynx, trachea, bronchi, and then enters the lungs. Exhaled air travels from the lungs in the opposite direction.
The respiratory system organs include the lungs, pharynx, larynx, trachea, and bronchi. After the larynx, air moves into the trachea, divides into the bronchi, sweeps through to the bronchioles and ends in the alveoli, which are surrounded by capillaries essential for gas exchange.
