| G. Give short answers for the following. | ANSWER FOR G: 1-7 |
| 1. What is the difference between hematuria and uremia? | Hematuria is the presence of blood in the urine, and uremia is a toxic condition of excess urea (nitrogenous waste) in the bloodstream. Hematuria is a symptomatic condition of the urine (-uria), and uremia is an abnormal condition of the blood (-emia). |

| 4. What is antidiuretic hormone? | Antidiuretic hormone is a hormone produced by the pituitary gland that normally helps the renal tubules to reabsorb water back into the bloodstream. It works against diuresis to help retain water in the blood. |
| 5. What is hyponatremia? | Hyponatremia is abnormally low levels of sodium in the bloodstream. |
| 6. What is hyperkalemia? | Hyperkalemia is abnormally high concentration of potassium in the blood. The major cause is chronic renal failure. |
| 7. What is PKU? | PKU is phenylketonuria. This occurs when there are high levels of phenylketones in urine and phenylalanine in the blood. The condition causes mental retardation in infants. |
