HUMAN RESPIRATORY SYSTEM - Coggle Diagram

- - - - Air from the mouth enters the Pharynx. This mixes w/ the air from the nasal passages. Intersection where food and air meets
        
        Larynx short air passageway between glottis and upper end of trachea. An instrument for vocal communication
        When swallowing food, it moves upward and tips the epiglottis over the glottis, which is the opening of the trachea.
        
        Trachea or windpipe are line with ciliated epithelium and is strengthened by a C-shaped bands of cartilage that prevents it from collapsing. located front of esophagus into the trachea
        
        Trachea splits into two bronchi which is also supported by cartilage bands
        
        bronchi branches off into Bronchioles which divides into smaller branches. The cartilage is gradually lost as the bronchioles decrease in diameter
- - - - Each lobe has its own bronchus which terminates into respiratory bronchioles from where the alveoolar ducts arise
        
        The alveolar ducts lead to alveoli (air sacs), the main site for gas exchanges
        
        The walls of the smallest bronchioles do not have cartilage but large amount of smooth muscle
        
        The alveolus is highly susceptible to outside particles due to lack of cilia, thus, it contains white blood cells. However, too much pathogens may lead to inflammation and irreversible damage in the alveolus
        
        A phospholipid surfactant prevents inward recoiling or deflating of the alveoli after every explanation by decreasing the surface tension in the lungs
        
        Respiratory Membrane is the junction between the endothelial cells of the capillary, alveolar epithelia (tissue).
