What is the composition of urine? Are glucose and proteins normally present in urine? Why? How is volume of urine regulated?
Answers
Explanation:
large elements like blood cells, platelets, antibodies, and albumin are present, as are some charged molecules.
Following filtrate production, the components in filtrate are modified by the nephron tubules until the final composition of urine has been attained in the collecting ducts. In the tubules, a good deal of water, electrolytes, and nutrients are removed from the filtrate and returned to the blood in the peritubular capillaries and vasa recta. Some additional wastes are also removed from the blood in those same capillaries and transported into the tubular filtrate. Both filtrate generation and nephron activity governing final urine composition are tightly regulated.
Answer:
Urine is a sterile waste product made up of water soluble products made from nitrogen.The kidneys secrete urine, a typically sterile liquid by-product of the body, through a mechanism called urination and excreted through the urethra. Urine is often used for many disease circumstances as a diagnostic function. These may b based on either physical or chemical components, that may give insight to processes within the body, often through urinalysis, a common clinical analysis of urine. Normal urine consists of water, urea, salts, and pigments.Urea is a non-toxic molecule made of carbon dioxide and toxic ammonia. Any abnormal urinary constituents are an indication of illness.Urine is an aqueous solution of greater than 95% water, with a minimum of these remaining constituents, in order of decreasing concentration:
Urea 9.3 g/L.
Chloride 1.87 g/L.
Sodium 1.17 g/L.
Potassium 0.750 g/L.
Creatinine 0.670 g/L.
Other dissolved ions, inorganic and organic compounds (proteins, hormones, metabolites).
