Slide 135 - Colon - for an example of very cellular areolar connective tissue, mainly in between the tubular glands. Look here for many wandering eosinophils; their granules are bright pink and quite refractile. You will also see many plasma cells; they have a smooth basophilic cytoplasm, with a pale negative Golgi area next to the eccentric nucleus. The nucleus has dark clumps of heterochromatin, often arranged next to the nuclear envelope in a cartwheel pattern.
