Some substances that were not initially filtered in the glomerulus, but must be eliminated from the blood, become a component of urine through the process of urine formation.
Urine: A liquid excrement consisting of water, salts, and urea, which is made in the kidneys then released through the urethra.
The process of urine formation involves 3 major steps:
- Filtration:- Blood enters the afferent arteriole during filtration, flowing into the glomerulus where filterable blood components—such as water and nitrogenous waste—move toward the interior of the glomerulus and nonfilterable blood components—such as cells and serum albumins—exit via the efferent arteriole.
- Reabsorption: During this, ions and molecules will be returned to the bloodstream. As the fluid's osmolarity (ion concentration) fluctuates, water and ions are eliminated as it moves through the proximal/distal convoluted tubules, the loop of Henle, and the collecting duct.
- The process of secretion involves the removal of various substances from the blood into the collecting duct, including hydrogen ions, creatinine, and medications. Urine, the final result of all these procedures, is essentially a collection of chemicals that have not undergone tubular or glomerular reabsorption.

Sugar-phosphates and nucleotides
Answer:
Lithosphere made the earth outermost layer, crust and upper portion of mantle.
Asthenosphere made the middle layer of earth.
Explanation:
Lithosphere:
Lithosphere made the earth outermost layer, crust and upper portion of mantle.
It is made up of tectonic plates.
Lithosphere present over the asthenosphere.
Lithosphere have low temperature as compared to asthenosphere.
Its rocks are rigid.
It is less viscous and dense
Asthenosphere:
Asthenosphere made the middle layer of earth.
When material present in asthenosphere solidify it becomes the part of lithosphere.
Asthenosphere have high temperature as compared to the lithosphere.
Its rocks are plastic and have tendency to flow.
It is more viscous and dense.
