What is the main difference between a bronchus and a bronchiole?
A bronchiole has no cartilage in its wall, a bronchus does.
What is themain differencebetween abronchus and abronchiole?
A bronchiole has no cartilage in its wall. a bronchus does.
What are the bronchiole walls made from?
I belive it's a mixture of cartilage and lung tissue containing cila.
Which respiratory structure is comprised of cartilage and ligaments?
That tube is called the trachea. It is also known as the windpipe.
Describe the structure of a terminal bronchiole and its alveolar sac?
A terminal bronchiole is a small airway that marks the end of the conducting zone in the respiratory system. It is lined with simple cuboidal epithelium and surrounded by smooth muscle. The terminal bronchiole branches into alveolar sacs, which are clusters of alveoli where gas exchange occurs. Alveolar sacs have thin walls composed of simple squamous epithelium and are surrounded by a network of capillaries.
Which type of bronchioles don't have cartilage?
Terminal bronchioles do not have cartilage in their walls.
What is the route of air from the external nares to alveolus?
Air enters the external nares, passes through the nasal cavity, travels down the pharynx, enters the larynx, moves through the trachea and bronchi, and finally reaches the alveoli in the lungs where gas exchange occurs.
What are the 3 types of bronchioles?
The three types of bronchioles are terminal bronchioles, respiratory bronchioles, and conducting bronchioles. Terminal bronchioles are the smallest airways in the respiratory system that lead to the respiratory bronchioles where gas exchange occurs. Conducting bronchioles are larger airways that branch off the main bronchi and help to conduct air to the smaller bronchioles.
What is the order of passageways from proximal to distal?
The order of passageways from proximal to distal in the human body is typically mouth, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (cecum, colon, rectum), and anus.
Trace the flow of air from nares to alveoli?
1. External Nares 2. Vestibule 3. Internal Nares 4. Nasopharynx 5. Oropharynx 6. Laryngopharynx 7. Larynx 8. Trachea 9. Primary Bronchus 10.Secondary Bronchus 11.Tertiary Bronchus 12.Bronchioles 13.Terminal Bronchiole 14.Respiratory Bronchiole 15.Alveolar Duct 16.Alveolar Sac 17.Alveolus
What is the medical term meaning bronchiole?
Bronchiole is the medical term meaning small bronchi
What is the next smaller branch of the respiratory passageway after the tertiary bronchus?
The next smaller branch of the respiratory passageway after the tertiary bronchus is the bronchiole, which further divides into terminal bronchioles, respiratory bronchioles, and ultimately alveolar ducts and sacs where gas exchange occurs.
