Urine differs in composition from the fluid that first enters a nephron tubule by filtration because <u>filtrate has more salts because of reabsorption and secretion</u>.
Filtrate is the liquid that is formed in the kidneys while urine formation is taking place. Water is the major component of urine, forming about 95% of it while the remaining part is formed by other organic and inorganic constituents.
As blood flows through the glomerulus, blood pressure pushes water and solutes from the capillaries into the capsule through a filtration membrane.
