The microcirculation (defined as blood vessels with diameter. Cristina Pires Camargo, Rolf Gemperli, in Endothelium and Cardiovascular Diseases, Abstract. Cutaneous microcirculation is responsible for thermoregulatory exchange, excretion of several substances such as water and minerals and protection against external stressors such as heat and cold.

Thus skin microcirculation plays a significant role in human body homeostasis as well as in several. The human conjunctiva is a richly vascularized transparent tissue that provides both protection and lubrication to the eye and is readily accessible for examination by a variety of techniques.

Measurements of conjunctiva blood flow in human eyes have been reported using a modified scanning laser ophthalmoscope (Duench, et al., ).Cited by: The conjunctiva is Microcirculation of human conjunctiva book tissue that lines the inside of the eyelids and covers the sclera (the white of the eye).

For ophthalmologists, optometrists, medical, dental, and optometry students, eye-anatomy forms the basis for eye-pathology in diseases: dry eye, retinal detachment.

(or the bulbar) conjunctiva, which is the focus of this study. The ocular conjunctiva is very thin and clear; thus the vasculature (including those of the episclera) is easily visible through it. The visible microcirculation of conjunctiva offers a rich and complex network of. Growth in knowledge about the microcirculation has been explosive with the field becoming fragmented into numerous sub-disciplines and subspecialties.
