• Pharynx - It is a passage behind the nasal chamber and serves as the common passageway for both air and food. (tiesen.nl)
  • It is a common passageway for both air, food and fluid. (criticalcarepractitioner.co.uk)
  • Trachea The trachea, also called the windpipe, is part of the passageway that supplies air to the lungs. (healthline.com)
  • The process of oxygen and carbon dioxide exchange begins in the nose and mouth, where air is inhaled through the nostrils and mouth and then travels down the trachea (windpipe) and into the bronchi, which are tubes that branch off from the trachea and lead to the lungs. (columbia.edu)
  • Bronchial tree The lungs begin at the bottom of your trachea windpipe. (columbia.edu)
  • THE HUMAN RESPIRATORY SYSTEM The respiratory system consists of the nose, pharynx (throat), larynx (voice box), trachea (windpipe), bronchi, and lungs. (slideshare.net)
  • 2. The lower respiratory system includes the larynx, trachea, bronchi and lungs. (slideshare.net)
  • The conducting portion of the respiratory tract begins at the nose and nasal cavity and extends through the pharynx of the upper respiratory tract and the larynx, trachea, bronchi, and larger bronchioles (airways of the lower respiratory tract). (tiesen.nl)
  • The trachea extends further down into the breastbone and splits into two bronchi, one for each lung. (tiesen.nl)
  • A)the upper respiratory tract includes components of both functional portions B)the trachea is part of the lower respiratory tract but not of the bronchial tree C)stratified epithelia occur only in parts of the tract shared by another system The respiratory portion includes the respiratory bronchioles and alveoli. (tiesen.nl)
  • At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. (connecticutchildrens.org)
  • This piece curves downward, extending into the two bronchi - the main passageways to the lungs - forming an imperfect circle that encloses each bronchus. (healthline.com)
  • The lungs are the main part of your respiratory system. (healthline.com)
  • The main function of the lungs is to extract oxygen from the air we breathe and deliver it to the bloodstream through a network of tubes and passageways called the bronchial tree. (columbia.edu)
  • Bronchi are ensheathed by a layer of connective tissue which is continuous with the other components of the connective tissue of the lungs. (columbia.edu)
  • Wheezing most often comes from the small breathing tubes (bronchial tubes) deep in the lungs. (stlukes-stl.com)
  • Tiny hairs called cilia (SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air. (connecticutchildrens.org)
  • It is a passageway for sperm and fluids from the reproductive system and urine from the urinary system . (cancer.gov)
  • The bronchi branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli. (en-academic.com)
  • The bronchial tree branches out into smaller tubes called bronchi, which further divide into bronchioles and eventually lead to the alveoli in the lungs. (proprofs.com)
  • Dichotomously branching tubes spanning 23 generations across the trachea and reaching all across the alveoli form the passageways of air whose most important function is ventilation. (lungswiki.com)
  • Caption2 = Front view of cartilages of larynx, trachea, and bronchi. (en-academic.com)
  • The larynx is responsible for producing sound and protecting the airway, while the trachea serves as the main airway that connects the larynx to the bronchial tree. (proprofs.com)
  • Airway obstruction is the primary sign that causes diseases of the smaller passageways of air. (lungswiki.com)
  • Asthma is hyperreactivity of the bronchi with an inflammatory component, often in response to allergen s. (en-academic.com)
  • Warm fluids may be more beneficial than cold ones because warm fluids - not only water but also tea, apple juice and chicken broth - will increase mucus flow and prevent the mucus from stopping up your nasal passages and bronchial tubes. (moonbites.es)
  • There are two main types: acute and chronic. (en-academic.com)
  • This is stated to be a chronic cause and emanating from the bronchial responses to various stimuli. (lungswiki.com)
  • Smooth muscle is present continuously around the bronchi. (en-academic.com)
  • This includes deposition of infiltrates reducing the luminal diameter, thickening of the passageways of air, smooth muscle hypertrophy, and the destruction of the support system of the airways that are structured. (lungswiki.com)
  • The lobar bronchi divide into tertiary bronchi . (en-academic.com)
  • The segmental bronchi divide into many primary bronchiole s which divide into terminal bronchiole s, each of which then gives rise to several respiratory bronchiole s, which go on to divide into 2 to 11 alveolar duct s. (en-academic.com)
  • COPD for long is recognized as the most common form of the disease of the smaller passageways of air. (lungswiki.com)
  • The harmful constituents in comparison to gases take a much longer time for diffusion and directly contribute to increasing the contact time with the smaller passageways of air leading to inflaming the same. (lungswiki.com)
  • In humans, the main muscle of respiration that drives breathing is the diaphragm. (everipedia.org)
