IV. Reading Comprehension: Please choose the BEST answer for each question according to the contents.Passage A      The kidneys are located in the posterior part of the abdomen. The right kidney sits just below the liver,while the left kidney is under the diaphragm, next to the spleen. On the vertebral level, they are approximatelypositioned from T12 to L3. In a normal human adult, the kidneys are about 12 centimeters long and fivecentimeters thick, and weigh 150 grams. They filter the blood and secrete water and nitrogenous waste (urea,creatinine, and so forth) in the form of urine. The medical field that studies the functions and diseases of thekidneys is called nephrology.    The kidneys are composed of nephrons. Each nephron consists of a glomerulus, Bowman’s capsule, andrenal tubule. There are more than a million nephrons within a healthy adult kidney. The vital function of thenephron is to remove waste from blood plasma. It also helps to maintain a normal fluid balance in the body byreabsorbing water and some electrolytes back into the blood.     Urine is formed by a process of filtration and reabsorption in the nephron. Blood enters the nephron via thearteriole. As it passes through the glomerulus, water is filtered through the glomerular membrane and collectedin the Bowman’s capsule. The filtrate then passes through the proximal tubule, loop of Henle, distal tubule, andcollecting tubule. Other substances, such as uric acid and hydrogen ions, are also added to the urine.
