The smallest structural unit of a protein is the amino acid. The smallest functional unit of a protein is a little ambiguous, because some might consider the amino acid to be functional (after all, some can function as neurotransmitters). Or, some might consider the peptide (di, tri, etc) to be a functional unit. One could argue what exactly is the smallest functional unit of a protein.

No. The functional unit of the nervous system is the neuron. Neurons group together to form nerves.
The microscopic, functional unit of the kidney and the site of urine-production is the Nephron.
This unit is called the nephron.nephronnephronsglomerulus/ glomeruli and associated nephronsnephrons
Two or more proteins that join to form a functional unit is the quaternary structure of a protein. An example is joining two or more polypeptides together to form a functional unit.
