Adventitia

Adventitia

Mucosa

submucosa

Type of tissue in esophagus

The respiratory bronchioles lead into the

walls consist of diffusely arranged rings of smooth muscle cells, connective tissue fibers and outpocketing alveoli

thin walled air sacs

Air is moved into and out of the lungs so the gases there are continuously changed and refreshed

oxygen diffused from the lungs to the blood, and carbon dioxide diffuses from the blood to the lungs

oxygen is transported from the lungs to the tissues cells of the body, and carbon dioxide is transported from the tissue cells to the lungs.

oxygen diffuses from blood to tissue cells and carbon dioxide diffuses from tissue cells to blood

the actual use of oxygen and production of carbon dioxide by tissue cells is known as

the two zones of the respiratory system

actual site of gas exchange

composed of the bronchioles, alveolar ducts and alveoli

provide fairly rigid conduits for air to reach the gas exchange sites

cleanse, humidify and warm incoming air

Separates the nasal cavity from the oral cavity

anteriorly, where the palate is supported by the palatine bones and processed of the maxillary bones

the unsupported posterior portion of the palate

the roof of the nasal cavity is formed by what two bones

connect pharynx to trachea. Has framework of cartilage and dense connective tissue.

air passageway, prevents food from entering lower respiratory tract

opening of the larynx

houses true vocal cords

flexible tube running from larynx and dividing inferiorly into two main bronchi.

walls contain C-shaped cartilages that are incomplete posteriorly where connected by trachealis

air passageway, cleans warms and moistens incoming air

main site of gas exchange

serous membranes

produce lubricating fluid and compartmentalize lungs

located in the roof of the nasal cavity

lines most of the nasal cavity

pseudostratified ciliated columnar epithelium

what does the respiratory mucosa contain

the groove inferior to each concha is the

connects the nasal cavity and mouth superiorly to the larynx and esophagus inferiorly.

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

lies posterior to the oral cavity and is continuous with it through an archway called the isthmus of the fauces

the tonsils that lie embedded in the lateral walls of the oropharyngeal mucosa just posterior to the oral cavity

the tonsil that covers the posterior surface of the tongue

lies directly posterior to the upright epiglottis and extends to the larynx where the respiratory and digestive pathways diverge

the voice box

superiorly attaches to the hyoid bone and opens in the laryngopharynx. Inferiorly it is continuous with the trachea

provide a open airway, act as a switching mechanism to route air and food into the proper channels and house the vocal cords

cartilage of larynx

inferior to the thyroid cartilage and is ring shaped

cartilages that form the lateral and posterior walls of the larynx

the epiglottis is what kind of cartilage

the vocal folds and the medial opening between through which air passes are called

another name for the false vocal cords

what kind of cells line the superior portion of the larynx

the tracheal wall consists of what kind of cartilage

the outmost layer of the connective tissue in the trachea

which main bronchus is wider, shorter and more vertical

which side of the lung only has two lobes

secrete a fluid containing a detergent like substance called surfactant

epithelium lining of nasal cavity

epithelium lining of nasopharynx

epithelium lining laryngopharynx

epithelium lining trachea and main bronchi

epithelium lining bronchioles

epithelium lining walls of alveoli (type I alveolar cells)
