Specializations of the alveoli Flashcards
The coating of Lipo proteins on the inner surface of the Alveoli helps to maintain __________, thus preventing them from collapsing and sticking together during ________
Surface tension, exhalation
Alveolar walls are only……
This aids in
One cell thick, diffusion
What are Alveoli made up of?
Squamous (flat) epithelial cells
The Alveoli surfaces have a very rich blood supply from the _____________ do you ensure maximum diffusion. These are highly ___________.
Pulmonary could pillories, vascularized
What are stretch receptors?
They are nerve endings that are sensitive to stretch
How do you stretch receptors work?
During inhalation these signal when the alveoli is full enough or stretched. This marks on side of exhalation
They are up to ________________ in the human lung. This provides a ___________________ for diffusion
300 million, great surface area
The alveoli have a coating of __________ on their inner surface
Lipoprotein
They are very _________________
Numerous
What kind of receptors are alveolar supplied with?
Stretch receptors
I’ll be early or also very thin__________
