Nasal Cavity, Pharynx, Larynx, Trachea, Bronchi, Bronchioles, Alveoli
Nasal cavity- The nasal cavity has three key components: vestibule, main nasal cavity and the paranasal sinuses. Here we see the vestibule, the area within the nostril. The epithelium here represents a continuation of the keratinized, stratified squamous epithelium of the outside skin. Within the vestibule are vibrissae (hairs) that serve to filter out the larger particles entering in the inhaled air
Pharynx- essentially same cell type, dont forget the mucous secretions- essentially same fxn
Larynx- The larynx is situated between the pharynx and the trachea.
Photographs of the larynx in situ. The vocal folds separate during breathing and lie close together to vibrate during phonation
T
he pharynx is situated between the nasal cavity and the larynx. The portion exclusively used for breathing (nasopharynx) is lined by the usual pseudostratified ciliated epithelium (respiratory epithelium) found throughout most of the conducting portion of the respiratory system. The remaining components of the pharynx (oropharynx, hypopharynx) are lined by a protective stratified squamous epithelium, appropriate to their role in abrasive activities such as swallowing and coughing.
The trachea extends from the larynx to the primary bronchi of the lung. It consists of a series of C-shaped hyaline cartilage rings that keep the airway open (the esophagus, which lacks such rings, is collapsed except when swallowing). The posterior, open ends of the cartilage rings are connected by trachealis muscle. This muscle contracts to narrow the trachea during coughing, providing a faster air flow. Elastic fibers in the mucosa and submucosa provide flexibility to the trachea
After the trachea, inspired air passes to the bronchi, distributing bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs and alveoli. Gas exchange occurs in alveoli, which first appear on the respiratory bronchioles.

The conducting zone of the respiratory system does not?
exchange gases with the blood
What is included in the conducting zone of the respiratory system?
Nasopharynx, larynx, trachea, bronchi and bronchinles.
What consists of the respiratory conducting zone?
nostril,nasal cavity,epiglottis,trachea,bronchi,lungs,bronchioles,alveoli isthe answerafter the nasal cavity and trache air moves into the brinchi, into the bronchioles and intp the alveiolie where gases are exchanged (co2) carbon dioxide and (o2) oxygen
What are the smallest and most distal structures that remain a component of the conducting zone in the respiratory tract?
terminal bronchioles!
Different between respiratory zone and respiratory membrane?
conducting zones are the upper respiratory tract which is the passage of air and functions to humidify, flter and warm the air. by:- cabdulaahi niyo
What is dead space volume?
the air that enters the respiratory tract remaining in the conducting zone pasageways and never reaches the alveoli.
What are the structures in the conducting zone of the respiratory system?
Conducting is made up of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. The physical structure that "conducts" air and allows it to pass in and out of the lungs. Respiratory is made up of alveoli, alveolar ducts, and respiratory bronchioles. This is where the real respiration and gas exchange takes place.
What are the parts of the plant system?
Root cap, meristematic cells zone, root hair zone, mature tissue system etc.
The respiratory zone of the tracheobronchial tree includes?
respiratory bronchioles, alveolar ducts and alveoli
What is the last division of the conducting zone?
terminal bronchioles
Which structure in the respiratory zone has the thinnest wall?
ALVEOLI
Tubular airways that begin the respiratory zone?
Primary bronchus
