Kidney Nephron Under Microscope. The major calyces merge to form a large renal pelvis. A nephron consists of two main parts.

Only a light or electron microscope can reveal these structures. Under the microscope each nephronis a long extremely fine tube about 30 55 mm 1 2 2 2 inches long having several components and sub components. Nephron is the functional filtration unit of kidney.
The kidneys reside against the back muscles in the upper abdominal cavity.
Only a light or electron microscope can reveal these structures. Parts and their functions it consists of three parts. A renal corpuscle and its associated renal tubule system. Even then serial sections and computer reconstruction are necessary to give us a comprehensive view of the functional anatomy of the nephron and its associated blood vessels.
