Urine-formation-ppt.pptx A powerpoint on the mechanism of urine production

A powerpoint presentation on the mechanism of urine formation.
It starts by introducing us to the kidneys and nephron, which is the basic functional unit of the kidneys.
It continues by introducing us to the topic: The Mechanism of urine production.

3. Urine Formation Waste is excreted from the human body, mainly in the form of urine. Our kidneys play a major role in the process of excretion. Constituents of normal human urine include 95 percent water and 5 percent solid wastes. It is produced in the nephron, which is the structural and functional unit of the kidney. Urine formation in our body is mainly carried out in three phases namely Glomerular filtration Reabsorption Secretion

4. Normal Chemical Composition of Urine 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).
