From the original filtrate, a lot of much needed electrolytes (Sodium e.t.c) are reabsorbed (absorbed back into blood), a few substances secreted further into the urine, then loads of water reabsorbed to fine tune body water to exactly how much you need(as much as possible), making urine far more concentrated than the original filtrate.
The water concentration in urine is generally lower than that in glomerular filtrate. During the filtration process in the kidneys, glomerular filtrate contains a high concentration of water, but as it passes through the renal tubules, water is reabsorbed, leading to a more concentrated urine. Therefore, urine typically has a higher concentration of solutes and a lower concentration of water compared to the initial glomerular filtrate.
The filtrate is converted into urine primarily in the nephron, the functional unit of the kidney. This process occurs mainly in the renal tubules, where selective reabsorption and secretion take place. As the filtrate passes through the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct, water, electrolytes, and waste products are adjusted, resulting in the formation of urine. Ultimately, urine is collected in the renal pelvis before being excreted from the body.
Secretion of substances into the filtrate occurs primarily in the distal convoluted tubule and the collecting duct in the nephron of the kidney. This process helps in regulating the composition of the urine by removing additional substances from the blood and adding them to the filtrate for excretion.
Tubular filtration is the process in the kidneys where blood is filtered through the glomerulus of the nephron to form filtrate. This filtrate contains water, ions, and small molecules that will eventually be reabsorbed or excreted as urine.
Urea concentration is higher in urine than in the filtrate because the kidneys reabsorb water and certain solutes during the filtration process. As the filtrate passes through the renal tubules, water is reabsorbed, concentrating the remaining solutes, including urea. Additionally, urea is actively secreted from the blood into the tubular fluid, further increasing its concentration in the final urine. This process helps regulate nitrogen waste excretion while conserving water.
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.

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
In the renal pelvis

Blood, proteins, and sugars are absent from the filtrate and urine of a healthy adult. If any of these are present it is a sign that something is not right and should be addressed right away.
