Urine is formed from blood.
The process of urine formation is that blood passes through the glomerulus and the inner wall of the renal capsule for filtration to form primary urine, and then passes through the renal tubules and collecting ducts for selective reabsorption, which absorbs nutrients and ions from the primary urine and filters out some unwanted substances, such as creatinine and acids, and then forms urine. So it can be considered that urine is formed from blood.
The main purpose of urine is to remove metabolic wastes and excess water from the body, and the body’s metabolism produces a large number of metabolites, such as creatinine, urea and so on. Routine examination of urine is often performed clinically to determine whether there is any abnormality in the human body, such as the amount of creatinine in the urine, which can determine the filtration of the kidneys. Or the presence of red blood cells in the urine, it may be the occurrence of hematuria.
If the patient has urine abnormalities, it is recommended to go to the regular hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
