In healthy lungs, lymphatics run parallel to the major airways and respiratory bronchioles, and they also exist in close proximity to the intralobular arterioles and small veins. Lungs themselves are made of a soft, spongy material that contain no muscle at all. The major respiratory structures include the lungs, nose, trachea, and bronchi. Increase unloading, as concentration of 02 decreases. Excitatory impulses reaching respiratory centers from proprioceptors in moving muscles, tendons and joints. protection . The respiratory center. The trachea leads to the: bronchioles bronchii esophagus pulmonary vessel. External Muscles. The human respiratory is sorely charged with taking in oxygen and dispersing carbon dioxide. A pathway for oxygen to enter the lungs. Acts more as a protective response. Closes during swallowing to prevent food from entering the nasal cavity.
