bronchiole उदाहरण वाक्य

The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles and which receive air lobes.
Bronchiole, smooth muscle that line the airways of the lung, respond to high carbon dioxide producing vasodilation and vasoconstrict when carbon dioxide is low.
"' Chest wall oscillation "'is when devices are used for clearing excess mucus from lung airways ( bronchi and bronchioles ).
The respiratory tree, comprising the larynx, trachea, and bronchioles, is lined by ciliated epithelia cells that are continually exposed to harmful matter.
Even though the cross-sectional area of each bronchus or bronchiole is smaller, because there are so many, the total surface area is larger.

They have been hypothesized to derive from an undifferentiated multipotent malignant stem cell precursor that is generated in distal bronchioles via an as yet unknown oncogenetic driver.
This means there is less resistance at the terminal bronchioles . ( Most resistance is around the 3-4 division from the trachea due to turbulence .)
If left untreated, DPB progresses to bronchiectasis, an irreversible lung condition that involves enlargement of the bronchioles, and pooling of mucus in the bronchiolar passages.
DPB is classified as a form of " primary bronchiolitis ", which means that the underlying cause of bronchiolitis is originating from or is confined to the bronchioles.
Uniquely among Mesozoic mammal fossils the internal organs are also preserved, deposits of iron marking the position of the liver and microscopic structures being interpreted as the bronchioles.
