A cast, therefore, indicates the condition of the tubule in which it is formed.
The large swollen cells are granular, and very frequently there is a granular mass in the lumen of the tubule.
Inner and outer aperture of the tubule of the same size; their diameter equal to their length and distance.
In some cases the cells are so much swollen that the lumen of the tubule is represented merely by a star-shaped radiating chink.
The thin wall of the capillaries within each capsule separates the blood from the cavity of the tubule.
This tubule, which does not extend beyond the surface of the cellular coat, is liable to be broken off in dried specimens.
tubule tu·bule (tōō'byōōl, tyōō'-)
