Ok, let's analyse it in biochemistry and phisiological way. First up, urine is the product filtered by your kedney from blood. urine include something you didn't need any more, and your kedney helped you to clear away the blood with waste. Amazingly, kedney cannot filter a lot of things, include(just as you say) protein, most of glucose, axunge, edc. They are nessessary things when we alive.Let's imagine this scence: blood like roads in real world, and the nutrients like cars with our own. They can go anywhere but with our control. Through the road, they from our home to our work places, or the shopping mall. Different car have different destination . The kedney like scrap yard, weed out the used.
Glomerular basement membrane and renal tubular is safeguard to protect the nutrients.

Explain why protein is not normally present in the urine of a healthy person but may be present in the urine of a person with glomerulosclerosis?
Protein is filtered from the blood by the glomeruli in the kidneys, but in a healthy person, most of the filtered protein gets reabsorbed in the renal tubules. However, in glomerulosclerosis, the structure and function of the glomeruli are impaired, leading to increased permeability and leakage of protein into the urine. This results in proteinuria, the presence of protein in the urine.

Why isn't protein normally found in urine?
