Midsagital Head
This structure divides the nasal cavity into two halves.
What is the nasal septum?
Which cells produce the mucus for the trachea?
Goblet Cells
Name this Organ
The Trachea
A patient is short of breath after running, and their breathing rate increases to bring in more oxygen. What is this increase in breathing rate called?
What is tachypnea?
According to the formula , what does it mean if the lungs have "high compliance"?
The lungs are highly distensible, pliable, and easy to inflate.
This part of the pharynx is located behind the nasal cavity.
What is the nasopharynx?
Where does the trachea split in the bronchi?
The Carina
Identify the structure indicated by the red arrow, the blue arrow, and the overall structure shown.
Red arrow: Type II pneumocyte
Blue arrow: Type I pneumocyte
Overall structure: Alveolus
A patient has inflammation of the membrane covering the lungs, causing sharp pain during breathing due to increased friction. What structure is inflamed?
What is the visceral pleura?
IC = 2,200 mL and FRC = 3,400 mL. Find the TLC.
TLC = 5,600 mL or 5.6 L
This structure prevents food or liquid from entering the nasal cavity when swallowing.
What are the uvula and soft palate?
What membrane covers the exterior of the lungs? What is its purpose?
The Visceral Pleura is a membrane covering the lungs. It's responsible for reducing friction during respiration.
Identify the part of the body this structure is attached to and describe its role.
Attached to: Lungs
Role: Reduces friction during breathing by secreting pleural fluid
A patient experiences airway collapse due to weakened C-shaped cartilage rings that normally keep the airway open. Which respiratory structure is affected?
What is the trachea?
Given
TV = 550 mL
IRV = 2,900 mL
ERV = 1,300 mL
RV = 1,200 mL
Find the FRC, IC, VC, & TLC.
FRC = 2,500 mL
IC = 3,450 mL
VC = 4,750 mL
TLC = 5,950 mL
These are the true sound-producing structures in the larynx.
What are the true vocal cords (vocal folds)?
Why does the left lung have less lobes than the right lung, what is in that space, and what is its name?
The unoccupied space is occupied by the heart; it is called the cardiac notch
Identify the overall tissue shown and identify #1 and its function
Tissue: Pseudostratified ciliated columnar epithelium
#1: Cilla and it moves mucus and trapped particles out of the airways
A person gets a pharyngeal tonsil infection, what part of the respiratory system is affected?
What is Pharynx?
Given:
IC = 3,350
IRV = 2,850
Respiratory rate: 12 breaths/minute
Find the minute ventilation (VE)
3,350mL-2,850mL = 500 mL
VE = 500mL/breath x 12 breaths/minute
VE = 6000 mL/breath
