व्याख्या
नेफ्रॉन गुर्दे की संरचनात्मक एवं क्रियात्मक इकाइयाँ हैं। ये रक्त का निस्पंदन (Filtration) करके अपशिष्ट पदार्थों को अलग करते हैं, जल एवं लवण का संतुलन बनाए रखते हैं तथा मूत्र का निर्माण करते हैं। प्रत्येक मानव गुर्दे में लगभग 10 लाख (1 million) नेफ्रॉन होते हैं।
बोमैन कैप्सूल केवल नेफ्रॉन का एक भाग है, जहाँ निस्पंदन प्रारंभ होता है।
