Solved in 4 steps
- Define Clearance. Describe creatinine /urea / Inulin clearance.The concentration of urea in urine is always much higher than the concentration in plasma. Does this mean that urea is secreted? Hint: remember that concentration is a ratio.What might it mean if you found a high concentration of urobilinogen in your patient’s urine?
- Are Xanthoproteic and MillonNasse tests satisfactory for use in the urinary examination for protein? Why? Which test can be used to show up to what stage the hydrolysis of a protein proceeds? Why?Give an example of renal handling of inulin?Why would you find proteins, glucose, ketones, bilirubin, and leukocytes in a urine sample? What does their presence indicate?
- How is urea formed in thehuman body?What is the significance of the coagulation of egg white to its digestion? Why is alcohol an effective disinfectant against bacteria? In what way can ingestion of heavy metals, such as lead and mercury, be detrimentalto the proteins in your body? Why is egg white used as an antidote for lead and mercury poisoning?Ammonia, NH3, and ammonium ion, NH4+, are both soluble in water and could be easily excreted in the urine. Why does the body convert them to urea rather than excreting them directly?
