Original Question

1. Seromucous glands secretions include: Defensins and lysozyme Lysozyme and mucous Defensins and mucous Interferons and mucous 2. The nasal cavity is covered with this kind of epithelial tissue: Simple cuboidal epithelium None of these is correct. Stratified squamous epithelium Pseudostratified, ciliated, columnar epithelium 3.This structure blocks the nasopharynx when we eat, so that no food gets up to our nose: Uvula Epiglottis Trachea Paranasal sinuses 4. The upper respiratory tract is made up of: The pharynx and larynx The diaphragm and the intercostal muscles The nose and pharynx The trachea and brochi 5. C rings of cartilage are found in this organ: Primary bronchi Pharynx Larynx Trachea 6. Stratified squamous epithelium is found: In the alveoli Where only air passes to the lungs In the trachea Where food shares the conduction system with air 7. The respiratory membrane is: Includes the interstitial space The basement membrane of the capillaries and simple squamous epithelium of the alveoli fused together. Two of these are correct Faster for the diffusion of gases. 8. Tidal volume is: The total amount of air a person has in their lungs. The amount of air forcibly inhaled after quiet respiration. The amount of air inhaled and exhaled during a quiet respiration. The total amount of air a person can inhale. 9. This system brings oxygenated blood to the respiratory tissues like the brochial tree. Pulmonary veins Bronchial arteries Pulmonary arteries 10. How does the nose humidify the air that comes in? The blood supply beneath the epithelial surface humidifies the air. Mucus is full of water, which humidifies the air. Conchae and meatus structures humidify the air 11. The left lung only has two lobes, while the right lung has three lobes. Why? Both lungs are the same size, there are just a different number of lobes. The heart sits in the cardiac notch of the left lung, taking up space. Both lungs have three lobes. 12. What are the functions of the nose? To warm and moisten incoming air. To act as an airway To cleanse and filter incoming air. All of these are correct. 13. Which organs are lined with pseudostratified, ciliated, columnar epithelium? Be complete. The trachea, bronchi and bronchioles. The nasal cavity, the top of the pharynx, the trachea, the bronchi. The alveoli The nasal cavity, the whole pharynx, the larynx, the trachea and the bronchi. 14. How does pseudostratified, ciliated, columnar epithelium protect the tissues below it? Mucus catches foreign particles and cilia sweep those foreign particles up, where they are swallowed into the stomach. There are macrophages present that engulf foreign microbes. This tissue secretes defensins, which interrupt cell membranes of foreign microbes. This tissue has many layers, so some can be sloughed off without damaging tissues below. 15. Which organ/s is lined with simple cuboidal epithelium? Alveoli Nose Bronchi Bronchioles 16. Which organ/s are lined with simple squamous epithelium? Nose Trachea Pharynx Alveoli 17. How are the tissues below the alveoli protected? Lysozyme is secreted Defensins are secreted Macrophages engulf anything foreign Mucus catches foreign particles and cilia sweep those foreign particles up, where they are swallowed into the stomach. 18. Which organ has plates of cartilage in it’s wall, but not a complete C-shaped ring? Larynx Bronchi Trachea Bronchioles 19. What is the lung volume where a person forces an inhale after a quiet inhalation? Tidal volume (TV) Residual volume (RV) Expiratory reserve volume (ERV) Inspiratory reserve volume (IRV) 20. What is the lung volume calculated by adding the TV + IRV + ERV? Vital capacity (VC) Total lung capacity (TLC) Residual volume (RV)
