The respiratory system consists of your lungs, trachea, and oral/nasal passage. There are 2 lobes of lung tissue in your left lung and 3 lobes in the right. The bronchi are upper airway and the trachea is the a cartilaginous tube that connects the nasal and oral airway leading to your bronchi and lungs. The epiglottis is a muscular valve that allows for breathing or swallowing. When you swallow, it opens and closes to allow food to pass into your esophagus and bypass the airway.

BlakeThe respiratory system is composed of organs such as the lungs, trachea, bronchi, and diaphragm. These organs work together to facilitate the exchange of oxygen and carbon dioxide between the body and the environment through a process called respiration. The respiratory system also includes structures like the nose, mouth, and bronchioles that help in breathing and filtering air.
