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?
terminal brobchiole is formed as a result of division of respiratory bronchiole. It is extremely thin and end up into alveolar sac ALVEOLAR SAC THESE ARE SMALL SACS WITH 8 TO 10 SACCULES CALLES ALVEOLI. IT HAS CENTRAL AIR PASSAGE. THESE ALVEOLI SERVE AS RESPIRATORY MEMBRANE AND HELP IN EXCHANGE OF GASES
Which type of bronchioles don't have cartilage?
Bronchioles don't have cartilage because they need to be able to constrict and dilate
What is the route of air from the external nares to alveolus?
Nostrils → Nasal Cavity → Pharynx → Larynx → Trachea → Main Bronchus → Lobar Bronchiole → Segmental Bronchus → Bronchiole → Terminal Bronchiole → Respiratory Bronchiole → Alveolar Duct → Atrium → Alveolus
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.
