Respiratory System (Respiratory System disorders (Chronic Obstructive…

- - - - Overinflation causes barreo chest
      - Cyanosis blue skin due to lack of oxygen in blood and tissue.
  - - - Squamous cell carcinoma
      - Adenocarcimoma
      - Small cell carcinoma
  - - - elasticity of lung decreases
      - Vital capacity decreases
      - Blood oxygen decreases
      - Stimulating effects of CO2 decreases
      - More risk of respiratory tract infection
- - - - Moving air in and out of the lungs
    - - Occurs in the mitochondria of the cell
      - Oxygen carried as oxyhemoglobin in blood
    - - Exchange of gasses between and body cells
- - - - CO2 respiration acts directly on medulla oblongata.
      - CO2 levels in the blood in the main regulatory chemical respiration
      - Oxygen Level Respiration
        
        Chemoreceptors in aorta and carotid artery
        
        Info sent to medulla Oblongata
        
        Physical Factors
        
        Increased body temperature
        
        Exercise
        
        Coughing
        
        Emotion
- - - - Olfactory receptors located in muscosa and superior surface
      - Rest lined with respiratory mucosa
      - Moistens air and traps incoming air particles
    - - Nasopharynx-Superior region behind nasal cavity.
      - Oropharynx-Middle region behind mouth
      - Larynopharynx- Inferior region attached to larynx
  - - - Connects larynx with Bronchi
      - Fairly Rigid because of the C-Shaped rings made of hyaline cartilage to keep air way open at all times
    - - Formed by division of trachea
      - Enters lungs at hilus
      - Right bronchus is wider,shorter and straighter than the left due to the presence of the heart on the left side =.
    - - Occupy most of thoracic cavity
      - Apex is near the clavicle
      - Base rest on diaphragm
      - Each lung is divided into lobes by fissures
      - Left and right lung are different
        
        Left lung is smaller than the right lung to the presence of the heart
        
        Right lung has 3 lobes while the left has only 2.
