Flashcards in February 9, 2016 - Respiratory Pathology Deck (12):
1

Maximum Lung Development

Occurs around age 10

2

Acinus

A cluster of cells that resembles a berry.

In the lungs, this is in the respiratory bronchioles where they terminate in acini, which are many-lobed sacs containing groupings of alveoli.

Type 1 Pneumocyte

Squamous cells (giving more suface area to each cell) and cover approximately 90-95% of the alveolar surface.

These cells are thin as they facililtate gas exchange between the alveoli and the blood in the capillaries.

Emphysema

Abnormal permanent enlargement of the airspaces distal to the terminal bronchiole with alveolar wall destruction and without obvious fibrosis.
