During reabsoption most of the water exits the nephron and enters the interstitial fluid. This increases the concentration of ions such as potassium in the nephron. In the collecting duct (at the very end) very little water is left and the concentration of potassium, sodium, etc ions rises (including urea). This is why urine is acidic.
The filtrate contains amino acids and vitamins, but urine does not.
Glucose in urine is a worrying sign, as it is a key symptom of diabetes. A lack of the hormone insulin would be responsible.
ADH is short for Anti Diuretic Hormone and it prevents excess water loss. As such, a hyper-secretion of ADH will result in less urine by volume, and the urine will have a lower concentration of water. Conversely, it will have a higher concentration of solutes (Sodium, Potassium, Urea, etc.)
Hyperproteinuria is the term for an abnormal high concentration of protein in urine.
the 4 stages in urine formation are.... 1- filtration: blood is filtered from the glomerulus into the bowmans capsule due to great pressure. the filtrate consists of water, nutrients, electrolytes and metabolic waste products 2- reabsorbtion: occurs in the renal tubules, reclaims useful substances for the blood 3- secretion: occurs in the renal tubules from peritubular capillaries. disposes of undesirable substances. 4- urine concentration and volume:when present, ADH (antidiuretic hormone), allows water to leave via the walls of collecting ducts, altering the urines concentration and volume. hope this helps.. :D
Insulin affects the concentration of glucose in the urine.
The filtrate contains amino acids and vitamins, but urine does not.
Until the liquid reaches the renal pelvis, it is "glomerular filtrate," when it reaches the pelvis, it is called "urine"
The main difference between filtrate and urine is the chemical composition of the two. Filtrate has almost all the substance that blood plasma has except blood proteins while urine only contains waste substances.

Phosphate ions, sulfate ions, potassium ions, urea, uric acid, creatine.

In fact, the kidney dose not receives the urine but it produces the urine by receiving the filtrate from the blood vessels . and the first part wich receives the filtrate is the " glomerus"
less urine is formed
K+ is more concentrated in the urine than filtrate because while other substances are reabsorbed into the capillaries through the large pores, the potassium mostly stays in the urine, which increases its concentration. Also, the pH of the body needs adjustments, which needs a large amount of K+ to be excreted through the excretory system to adjust to the optimum pH for the body.
