3.3.1 Gasping For Air
Question: Anatomy of Breathing
Answer: - When we inhale, we’re breathing in oxygen (O2)
When we exhale, we’re breathing out carbon dioxide (CO2)
- Inhaling expands lungs/makes them larger
- Exhaling shrinks the lungs/makes them smaller
Question: Role of Muscles in Respiration
Answer: Allows the lungs to contract, which helps you breathe
Question: What is asthma?
Answer: Respiratory condition marked by spasms in the branch of the lungs, causing difficulty in breathing; usually results from an allergic reaction or other forms of hypersensitivity
Question: Characterizations of Asthma
Answer: - Coughing
- Wheezing
- Shortness of Breath

Question: Function of Nose and Nasal Cavity
Answer: - Nose: used to inhale air into the body
- Nasal Cavity: warms the air as it enters, acting as filtration and purifying the air by removing any dust, pollen, and other contaminants, before it passed to the inner body
Question: Function of Mouth
Answer: - Allows more inhalation
- Air also has less distance to travel, meaning more air can enter your body and be used faster
Question: Function of Pharynx
Answer: - Used for swallowing food as well as breathing
- Epiglottis ensures that air can pass into the trachea, and that food enters the esophagus
Question: Function of Larynx
Answer: - Allows us to speak
- Acts as a defense mechanism —-> If any food passes into the esophagus when swallowing, the larynx produces a strong cough reflex
Question: Function of Trachea
Answer: - Provides a clear and unhindered airway for air to enter and exit the lungs
- Inside the trachea, small hairs reside upon the inner walls —-> These hairs catch dust and other contaminants from inhaled air, which are later expelled via coughing
