explain why protein is absent in urine
Answers
Explanation:
Because when the Glomeruli (the primary filter of the kidney) are working at their best, they keep even the smallest molecular weight protein (Albumin) out of the urine filtrate.
So turning your question around, urine protein starts with albumin at 66437 daltons and increases with more complex proteins being lost as the filters weaken. … AND THAT IS WHEN THE TROUBLE STARTS:
* more protein puts a burden on the liver to keep up with replacement
* more protein will eventually degrade the second filter of the Nephron, the tubules
* The liver fails to keep up and an osmotic shift allows fluid to be retained in the tissues
* loss of reabsorption of valuable nutrients (proteins, Sodium, Ca, Mg, glucose)
* inability to excrete phosphates, urea, potassium, creatinine
* blood loss and loss of plasma renin to stimulate RBC production.
