Description

This detailed anatomical illustration depicts a fenestrated capillary, a specialized blood vessel characterized by small pores (fenestrations) within its endothelial lining. These openings, covered by thin diaphragms, facilitate the rapid exchange of fluids, nutrients, and small molecules while maintaining selective permeability. Commonly found in the kidneys, intestines, and endocrine glands, fenestrated capillaries play a crucial role in filtration and absorption processes. This visual serves as an essential educational resource for understanding microcirculatory function and the unique structural adaptations of these capillaries in various tissues.
