Create PARADIGM based on your understanding of the structural characteristics of the parts of the respiratory tract. You may include the following parts/terminologies that you may connect with a proposition: lining epithelium, submucosa, hyaline cartilage, trachealis muscle, seromucous glands, goblet cells, mucociliary escalator, respiratory epithelium, etc.

- ****Respiratory SystemThe respiratory system functions in the exchange of gases between the external and internal environments. Major parts of the system include the nasal cavity, larynx, trachea, bronchi, and pulmonary alveoli. Some regions of the respiratory system are specialized for the conduction of gases and other areas function primarily in the exchange of gases. Filtration mechanisms exist in both regions. The function of each part of the respiratory system is reflected in the structure of its wall: the type of epithelium and its apical modifications, intraepithelial and subepithelial glands, cartilaginous rings and plates, smooth muscle and elastic tissue, and the relationship of capillary endothelium to alveolar epithelium. Study the Respiratory system in Slide Box and Respiratory system under EM, briefly answer the question.

Which of the following statements is correct about these structures? The visceral pleura lines the outside of the lungs, the parietal pleura lines the thoracic cavity, and the intrapleural space seals the two layers together The parietal pleura lines the outside of the lungs, the visceral pleura lines the thoracic cavity, and the intrapleural space seals the two layers together The thoracic cavity and lungs are only connected by the visceral pleura The thoracic cavity and lungs are only connected by the parietal pleura
- Lung model with heart, larynx and diaphragm Identify the following structures with the help of your textbook and the keys Larynx, trachea Thyroid cartilage, cricoid cartilage, tracheal cartilage Cricothyroid ligament, thyrohyoid membrane Inside the model (not shown in the picture): Esophagus, Bronchi: Main/Primary bronchus, Lobar/Secondary bronchus, Segmental/Tertiary bronchus, Terminal bronchiole Lungs: Apex, base, diaphragm. In the right lung: Transverse fissure, oblique fissure, superior lobe, middle lobe, inferior lobe. In the left lung: oblique fissure, superior lobe, inferior lobe, cardiac notchIdentify the epithelium lining a (any) component of the respiratory zone of the respiratory tract 1. simple squamous epithelium 2. simple cuboidal (ciliated) epithelium 3. simple columnar (ciliated) epithelium 4. pseudostratified columnar (ciliated) epithelium 5. stratified squamous epithelium Choose the following: (A) 1, 2, and 3 (B) 1 and 2 (C) 4 and 5 (D) 2, 3, and 4 (E) 3, 4, and 5Mucous membranes (pseudostratified ciliated columnar epithelia) line most upper respiratory tract structures. Although these membranes filter the air by trapping pathogens in mucus, they are very delicate. Pieces of food passing through the oropharynx and laryngopharynx could damage this type of epithelium. Predict which type of epithelium protects the lining of the oropharynx and laryngopharynx.

QUESTION: Which cells are responsible from keeping the lungs free from obstructing particulate matter? How do they carry out this function?Most organs of the human body contain all four (4) tissue types working together to allow the organ to perform its specific function. From the image of the respiratory tract below: (1) indicate with arrows where those four tissue types may be found and name them next to the arrows in that section of the tract. (2) Briefly describe the functions of the four tissue types. In your answer you must include a unique structural feature of each tissue type that allows it to perform this function. (e.g., in the stomach, specialised epithelial cells secrete HCl acid for digestion).The electronic microphotography shows the structures in the form of open vesicles, the inner surface of which is lined with a simple epithelium, which is formed by respiratory and secretory cells. What are these structures? Bronchioles. O Alveolar duct O Terminal bronchi Acinous. O Alveoli
- The basolateral surface of the airway epithelium interacts with the extracellular matrix (ECM) and adjacent cells. Integrins stabilize the cell by attaching the cell's cytoskeleton to the ECM. The integrin protein, which passes through the plasma membrane, interacts with the extracellular matrix outside the cell, and the cytoskeleton inside the cell. What best describes how integrins are formed? a.) Integrins are translated by ribosomes attached to the rough endoplasmic reticulum, with their ECM binding site facing the lumen b.) Integrins are translated by ribosomes attached to the rough endoplasmic reticulum, with their ECM binding site facing away from the lumen c.) Integrins are translated by ribosomes located in the cytoplasm beneath the apical surface of the cell d.) Integrins are translated by ribosomes located in the cytoplasm beneath the basolateral surface of the cellLower respiratory tract consists of traehea, lungs, bronchi and diaphragm.
