Lymphocytes are a population consisting of both B- and T-lymphocytes. In blood smears they have the same morphology. One can see both small (slightly larger than an Rbc 7-8 um) and medium to large (up to 12 um); these represent inactive and activated lymphocytes respectively.
Spruces are large trees, from about 20â60 metres (about 60â200 feet) tall when mature, and can be distinguished by their whorled branches and conical form. The needles, or leaves, of spruce trees are attached singly to the branches in a spiral fashion, each needle on a small peg-like structure.
