NEPHRONS - The Kidneys' Filtration Units. Nephrons are microscopic tube-like structures in the kidneys that filter the blood and cause wastes to be removed. They are the most basic structures of the kidney's anatomy, and are an integral part of the urinary system. Each kidney contains over one million of them.
1 Identify the parts of the nephron responsible for filtration, reabsorption, and secretion, and describe the mechanisms underlying each of the functional processes. 2  Summarize the functions of the kidney.3  Explain the mechanism that maintains the medullary osmotic gradient (countercurrent mechanism).
