Answer 25

1. The upper respiratory tract extends from the *nostrils* up to the vocal cords. 2. The hairs in the nostrils trap larger *particles* preventing them from entering the respiratory tract. 3. The mucous membranes in the nasal cavities produce *mucus* that helps to humidify the air. 4. The upper respiratory tract adjusts the temperature of inhaled air close to *body* temperature. 5. The nasal cavities contain specialized cells called *olfactory* receptors, which are responsible for detecting odor molecules in the air. 6. The upper respiratory tract acts as a filter to remove large *particulates* present in the inhaled air. 7. The cilia in the nasal cavities help move *mucus* and trapped particles out of the respiratory tract. 8. The upper respiratory tract humidifies the inhaled air, ensuring that it is saturated with *water* vapor by the time it reaches the lungs. 9. The olfactory receptors send signals to the *brain*, which interprets the signal as a specific smell. 10. The lungs can only function efficiently within a narrow *temperature* range.

Question 26

1. Describe the process by which the upper respiratory tract humidifies the inhaled air.

Answer 26

The upper respiratory tract humidifies the inhaled air through the production of mucus by the mucous membranes in the nasal cavities and other parts of the upper respiratory tract. As the inhaled air passes over the mucous membranes, it picks up water vapor, becoming increasingly humid. By the time the air reaches the lungs, it is fully saturated with water vapor, which helps to prevent the lungs from drying out.

Question 27

1. What is the role of cilia in the nasal cavities and other parts of the upper respiratory tract?

Answer 27

The cilia in the nasal cavities and other parts of the upper respiratory tract play a crucial role in moving mucus and trapped particles out of the respiratory tract. The cilia beat in a coordinated manner to propel the mucus and debris upwards towards the nostrils, where it can be expelled or swallowed.

Question 28

1. Explain the importance of the upper respiratory tract in protecting the lungs from damage.

Answer 28

The upper respiratory tract plays a vital role in protecting the lungs from damage by filtering out large particulates, warming and humidifying the inhaled air, and detecting odor molecules. By removing particulates and other debris, the upper respiratory tract prevents them from entering the lungs and causing damage. Additionally, by warming and humidifying the air, the upper respiratory tract helps to prevent the lungs from drying out and becoming damaged.

Question 29

1. Describe the process by which the upper respiratory tract humidifies the inhaled air.

Answer 29

The upper respiratory tract humidifies the inhaled air through the production of mucus by the mucous membranes. As inhaled air passes over the mucous membranes, it picks up water vapor, becoming increasingly humid.

Question 30

1. What is the role of cilia in the nasal cavities and other parts of the upper respiratory tract?

Answer 30

The role of cilia in the nasal cavities and other parts of the upper respiratory tract is to move mucus and trapped particles out of the respiratory tract.

Question 31

1. Explain the importance of the upper respiratory tract in protecting the lungs from damage.

Answer 31

The upper respiratory tract protects the lungs from damage by filtering out particulates, warming and humidifying the air, and detecting odor molecules, preventing them from entering the lungs and causing damage.
