Introduction:
What is the main organ of the Respiratory system?
Lungs
The Upper Respiratory Tract is located:
Outside of the Thorax
What is the primary function of the nasal cavity?
Warm's and moisten's inhaled air, also contain's Olfactory Recepter's.
The Lower Respiratory Tract is located:
In the Thorax.
The top of the lung is called:
The apex.
What are the two Respiratory Tract's?
The Upper Respiratroy Tract include's:
Nose, Pharynx and Larynx.
What is the role of the epiglottis during swallowing?
The epiglottis covers the opening of the larynx to prevent food and liquid from entering the trachea.
The Lower Respiratory Tract include's:
The Trachea, Bronchial tree, and the lung's.
What is the main function of the alveoli?
Exchange of gases between air and blood.
What is the anatomical difference between the right and left lung?
The right lung has three lobes, while the left lung has two lobes to accommodate the heart.
What sinuse's drain into the nose?
Frontal, maxillary, sphenoidal, and ethmoidal sinuses.
The Lacrimal Sac's drain into the pleural cavity.
False.
The Lacrimal sac's collect tear's from our eyes and drain them into the nasal cavity.
Where does the lower respiratory tract begin?
It begins at the trachea, below the larynx
_______ lines the chest cavity, while _______ covers the lungs.
Parietal pleura, Visceral pleura
What muscle's are primarily involved in breathing?
The diaphragm and intercostal muscles.
Two nasal cavities, mouth, esophagus, larynx, and auditorytubes all have opening's into the larynx.
False.
They all have opening's into the pharynx.
What specialized membrane line's the air distribution tubes in the respiratory tree?
Respiratory Mucosa.
The goblet cells produce mucus to trap pathogens, and the cilia move the mucus for removal.
Which structure is 11cm long and extends from the larynx into the thoracic cavity?
The trachea.
Which membrane lines the air distribution tubes in the respiratory tree?
The respiratory mucosa.
What is the pleural cavity, and what is it's function?
It is the space between the visceral and parietal plurae, containing pleural fluid that reduce's friction between the lung's and the chest wall during breathing.
Describe the role of the upper respiratory tract:
The upper respiratory tract takes in air, filter's, warm's, and humidifies it before sending it to the lung's, while also enabling voice production, smell, and protection against irritant's.
The pharynx is divided into how many part's, and what are they called?
The pharynx is divided into three part's called:
Nasopharynx, Oropharynx and Laryngopharynx.
The tertiary bronchi brand into the ______, which lead to the ______.
Bronchioles, Alveoli
Which lower respiratory structure gets held open by C-shaped rings of cartilage?
Trachea
