What is the order of passageways from proximal to distal?
terminal bronchiole, respiratory bronchiole, alveolar duct
What is the srtucture between an alveoli and bronchiole?
Air enters the body through the nostrils or the mouth, passing down the throat to the larynx, and then to the trachea. The trachea divides into two branches in the chest cavity, the right and left bronchi that enter the lungs. The branches of the bronchi narrow down to tubes called bronchioles of less than 1 mm diameter, and these sub-divide into even narrower tubes called alveolar ducts. Each alveolar duct ends in a grapelike cluster of thin-walled sacs, called alveoli. From 300 million to 400 million alveoli are contained in each lung.
What produces surfactant?
type II alveolar cells
The typical cell making up the alveolar wall is the?
The alveolar sac, also called an alveolus, is lined by cells called type I pneumocytes.
What is an alveolar bone?
An alveolar ridge is a ridge which forms the borders of the maxilla and mandible, and contains the alveoli of the teeth.
What is a gland composed of cells arranged in a blind pocket with a single duct that does not branch?
Simple alveolar (acinar) because of single duct that does not branch compound alveolar
What is the small tube between the bronchus and the alveoli?
The alveolar duct
What is the direction of movement of gas between the blood and the alveolar duct?
i dint knoew the answer
What is the order of passageways from proximal to distal?
terminal bronchiole, respiratory bronchiole, alveolar duct
What Respiratory tubes are smaller connect the bronchi to the alveolar ducts and contain no cartilage?
bronchioles
What respiratory tubes are smaller connect the bronchi to the alveolar ducts and contains no cartilage?
bronchioles
What path does air take from the glottis to the respiratory membrane?
larynx, trachea, pimary bronchus, bronchi, bronchioles, terminal bronchiole, respiratory bronchiole, alveolar duct, alveolar sac, alveolus and respiratory membrane
What is the structure of alveolar ducts?
it dissolves oxygen in the fluid and from there it can diffuse to the alveolar cells.It goes right back to evolution where single cells have to absorb oxygen from water.All of our cells systems ae aquatic.
Inhaled air passes through which of the following last?
It goes: trachea Mainstem Bronchus lobar bronchus segmental bronchus bronchiole Alveolar duct Aveolus
Surfactant helps to prevent the alveoli from collapsing by what?
Interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid.
Trace molecule of oxygen from the external nares to the pulmonary capillaries of the lungs?
nose - nasal cavity - larynx - trachea - primary bronchus - secondary bronchi - tertiary bronchi - terminal bronchi oles - respiratory bronchioles - alveoli - alveolar sacs the alveolar sacs contain the pulmonary capillaries. the actual gas exchange occur here by simple diffusion. O2 goes from the lungs into the O2 depleted RBC.
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
