Each nephron consists of a glomerulus, tubules, and a collecting duct, working together to maintain the body's fluid and electrolyte balance...

Example: Blood filtration occurs in the glomerulus.
Example: Glucose is reabsorbed in the proximal tubule.
Example: Potassium ions are secreted into the distal convoluted tubule.
Example: The glomerulus filters blood to form filtrate.
