RESPIRATORY SYSTEM

• moving air into and out of the lungs

  PULMONARY VENTILATION
• gas exchange between the lungs and the blood

  EXTERNAL RESPIRATION
• transport of oxygen and carbon dioxide between the lungs and tissues

  TRANSPORT
• gas exchange between systemic blood vessels and tissues


  INTERNAL RESPIRATION
• the sensation of smell occurs when airborne molecules are drawn into the nasal activity

  OLFACTION
• external nose


  UPPER RESPIRATORY TRACT
• bronchi


  LOWER RESPIRATORY TRACT
• larynx


  LOWER RESPIRATORY TRACT
• internal nose - nasal cavity


  UPPER RESPIRATORY TRACT
• Pharynx


  UPPER RESPIRATORY TRACT
• lungs


  LOWER RESPIRATORY TRACT
• alveoli


  LOWER RESPIRATORY TRACT]
• passaageway for air


  NOSE
• passageway for food and air'

  MOUTH
• covers larynx during swallowing

  EPIGLOTTIS
• filters, warms, and ,moistens air


  NASAL CAVITY
• common passageway for air, food, and liquid

  PHARYNX
• production of sound


  LARYNX
• main airway or windpipe

  TRACHEA
• branching airways

  BRONCHI
• air sacs for gas exchange

  ALVEOLI
• cover the lungs and line the chest cavity

  PLEURAL MEMBRANES
• moves the ribs during respiration

  INTERCOSTAL MUSCLE
• allows air to pass into the lungs

  TRACHEA
• maintains an open airway and allows you to talk and make sounds when air moves in and out

  LARYNX
• branch into lungs


  bronchi
• responsible for the removal of oxygen from the air and passes into your bloodstream

  LUNGS
• made of cartilage and skin and is lined with mucous membranes

  EXTERNAL PORTION OF THE NOSE
• formed by frontal, nasal, and maxillary bones


  bony framework of the nose
• it is the open chamber inside the nose where air first enters the respiratory system

  NASAL CAVITY
• increase the surface area for air to be in contact with mucous membrane and aids in humidification and filtration

  NASAL CONCHAE
• creates pathways for air to flow through and play a role in drainage from the paranasal sinuses and nasolacrimal ducts

  NASAL MEATUSES
• produces mucous to trap dust, pollen, and other particles, and contains cilia that help move the mucus and trapped particles toward the pharynx for disposal

  MUCOUS MEMBRANE
• contains sensory cells responsible for detecting odors and facilitating the sense of smell

  OLFACTORY EPITHELIUM
• a funnel shaped tube that is about 13cm long that starts from the internal nares and extends to the circoid cartilage


  PHARYNX
• aids in defending against infections

  PHARYNGEAL TONSIL
• the voice box or the triangular chamber in front upper part of the neck; passageway that connects the pharynx and trachea

  LARYNX
• It is the landmark used to make an emergency airway called tracheotomy 


  CIRCOID CARTILAGE
• inflammation of vocal cords

  LARYNGITIS
• it is composed of 16-20C shaped pieces of cartilages and contains cilia pseudostratified epithelium; a tube that connects larynx to the bronchi

  TRACHEA
