In this article we will discuss about:- 1. Introduction to Reticulo-Endothelial 2. Classification, Varieties and Distribution of Reticulo-Endothelial Cells 3. Functions. Introduction to Reticulo-Endothelial: It has been known for many years that if a vital dye (viz., Trypan blue, Lithium carmine, etc.) be injected into a living animal, certain cells engulf the dye particles, whereas other do not. It is [...]

The excitability of different tissues varies widely. Some tissues are highly excitable whereas others are dull. While considering the excitability of a tissue two factors are to be considered: (a) The strength of the current used, and (b) The duration of the current flowing through the tissue. These two factors bear an inverse relation. The stronger the current the lesser [...]
