Which of the following are primary components of the respiratory system?

The respiratory system is primarily responsible for the process of gas exchange, which involves taking in oxygen and expelling carbon dioxide. The correct components of this system include the nose, trachea, lungs, bronchi, and alveoli.

The nose serves as the entry point for air, where it is filtered, warmed, and humidified. The trachea, or windpipe, acts as a passageway for air to travel to the lungs. Within the lungs, the bronchi branch into smaller airways leading to the alveoli. The alveoli are tiny air sacs where the actual exchange of oxygen and carbon dioxide occurs between the air and the bloodstream. This intricate structure and arrangement of components all work together to facilitate breathing and ensure that oxygen reaches the body's tissues while removing waste gases.

In contrast, the other options listed consist of components from different body systems that do not involve gas exchange. The kidneys, bladder, and ureters form part of the urinary system, responsible for waste removal and fluid balance. The heart, arteries, and veins belong to the circulatory system, which functions to transport blood throughout the body. Lastly, the stomach, liver, and pancreas are essential parts of the digestive system, which is involved in processing food and nutrient
