Does the urine and urine contain inorganic salts? Anxious
When the blood flows through the glomerular, in addition to blood cells and macromolecules of protein, the plasma part of the water, inorganic salts, glucose and urea and other substances, can be filtered through the glomeruli into the renal capsule, the formation of urine ; When the original urine through the renal tubular, which is useful for the human body substances, including most of the water, all the glucose and part of the inorganic salt, reabsorbed by the renal tubules, and into the capillaries outside the renal tube, To the blood; in the renal tubular reabsorption at the same time, renal tubular epithelial cells will produce substances (such as ammonia) secretion into the renal tubular bureaucratic, and the original urine of other waste, such as urea, part of the water and inorganic Salt, etc. from the renal tubular effusion, the formation of urine. Therefore, plasma, urine and urine are contained in the material is water, inorganic salts, urea.
Analysis: This question can be solved from the formation of urine. Kidney is the formation of urine organs, nephrons are the basic unit of renal structure and function, nephrons include glomerular, renal sac and renal tubules; urine formation process, including filtration, reabsorption and secretion of three processes.
