Human Anatomy & Physiology: Chapter 22 and cumulative exam Flashcards

Function of the conducting zone

which zone cleanses, humidifies and warm incoming air

passageway connecting nasal cavity to larynx and oral cavity to esophagus

houses the tonsils

passageway for air and food

connects pharynx to trachea

had framework of cartilage and dense connective tissue

house vocal folds

prevents food from entering lower respiratory tract

mucosa-lined, air filled cavities in cranial bones surrounding nasal cavity

descends from the larynx through the neck and into the mediastinum

located posterior to the nasal cavity, inferior to the sphenoid bone, and superior to the level of the soft palate

serves only as an sir passageway

formed by the fusion of two cartilage plates

forms part of the lateral and posterior walls of the larynx

anchors the vocal folds

composed of elastic cartilage and is almost entirely covered by a taste bud-containing mucosa

guardian of the airways

one of the microscopic air sacs of the lungs

one of the two large branches of the trachea that lead to the lungs

branching air passageways inside the lungs that are smaller the 1 mm in diameter

the point where the trachea branches into the two main bronchi

high sensitive and violent coughing is triggered when a foreign object makes contact with it

covers the thoracic wall and superior face of the diaphragm

continues around the heart and between the lungs, forming lateral walls of the mediastinal enclosure and snugly enclosing the lung root

covers the external lung surface, dipping into and lining it fissures
