Histometric analysis of sheathed capillaries in congestive splenomegaly
Abstract:
The structural rearrangement of human sheathed capillaries in congestive splenomegaly with hypersplenism has been evaluated by histometric analysis. In abnormal spleens the external diameter and the wall thickness were decreased, while the internal diameter was increased. Moreover, the total length and the absolute number of sheathed capillaries were increased, though not to the same high degree as the volume of the whole red pulp. Thus, in addition to the well-known changes of the sinuses, also the terminal arterial passages appear to participate in the morphological rearrangement of the red pulp in congestive splenomegaly.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
