Structures I
The vocal cords are located in which structure?
Larynx
The pharynx is also known as:
The throat
What is the primary function of the respiratory system?
Exchanging gases (oxygen and carbon dioxide)
How does the respiratory system work with the circulatory system?
By exchanging gases between air and blood
What is the primary cause of Chronic Obstructive Pulmonary Disease (COPD)?
Smoking & Air Pollution
How does tuberculosis primarily spread?
Through airborne droplets from infected individuals
Which muscle is considered the main muscle of breathing?
Diaphragm
What is the primary function of the intercostal muscles in respiration?
The help expand and contract the chest
What is the primary function of exhalation?
To remove CO2 from the body
How do the cilia in the trachea contribute to respiratory function?
By trapping particles
In the context of COPD, what is the primary purpose of bronchodilators?
To open up the airways and improve airflow
Name a typical treatment approach for asthma
Inhalers
Where does gas exchange primarily occur in the respiratory system?
In the alveoli
Which structure prevents food from entering the airways during swallowing?
Epiglottis
What is the main purpose of oxygen in the body?
To help cells produce energy
What role does the nose play in protecting the lower respiratory tract?
It filters, warms, and humidifies air
Why is the treatment for tuberculosis (TB) typically longer than for other respiratory infections?
To ensure complete eradication of the slow-growing bacteria
Which respiratory condition is characterized by inflammation of the air sacs, often filling them with fluid?
Pneumonia
The trachea is reinforced with:
C-shaped cartilage rings
How many lobes does each lung have? Why?
Right 3, Left 2
What is the main function of the bronchi and bronchioles?
To distribute air throughout the lungs
What is the main purpose of humidifying inhaled air?
To prevent drying and irritation of airways
Which respiratory condition is characterized by the destruction of alveolar walls?
Emphysema
What is a key difference between the effects of asthma and COPD?
Asthma is typically reversible, while COPD causes permanent damage
The pleura surrounds which respiratory structures?
The lungs
The branching airways within the lungs are called:
Bronchi & Bronchioles
How does negative pressure in the chest cavity contribute to respiration?
By drawing air into the lungs
How does the large surface area of alveoli contribute to respiratory function?
By allowing more efficient gas exchange
Why might Respiratory Syncytial Virus (RSV) be more dangerous for certain age groups?
It can cause more severe symptoms in infants and older adults
What is the primary genetic impact in cystic fibrosis?
It results in the production of thick, sticky mucus
