Solved in 2 steps
- Why are the loop of Henle and vasa recta important for the formation of concentrated urine?What might it mean if you found a high concentration of urobilinogen in your patient’s urine?Why would you find proteins, glucose, ketones, bilirubin, and leukocytes in a urine sample? What does their presence indicate?
- 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.Why would lipoid acid deficiency lead to metabolic acidosis in a human?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?
- 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?Why don't red blood cells usually appear in urine?In humans, uric acid is the final product of Allantoin metabolism, Amino acid metabolism, Purine metabolism, or the urea cycle?
