The pathway followed by a uric acid molecule in the kidney, from a glomerulus to the urethra. Introduction: The kidney is an important organ of the urinary system, which filters nitrogenous waste such as urea, ammonia, and uric acid in the body. Nephrons in the kidney filter all these waste products, which are then excreted out of the body. Uric acid is one of the waste materials released during purine degradation. When urine is highly concentrated in uric acid, it forms crystals that are called renal calculi.

The presence of either protein or glucose in a urinalysis is abnormal, but these two molecules end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen.

Which of the following pathways best describe the structures which urine has to flow through before being excreted out of the body? (Hint: some structures may be omitted, so just make sure the general order is correct) 1-Collecting duct -> bladder -> ureter 2-Collecting duct -> ureter -> bladder -> urethra 3-Collecting duct -> urethra -> bladder -> ureter 4-Major calyx -> minor calyx -> renal pelvis -> urethra

The process of hydrogen ion secretion in the proximal convoluted tubule occurs via which of the following mechanisms? Choose from the following: (A) hydrogen ions diffuse out of the glomerular filtrate of the proximal convoluted tubule, through extracellular fluid and into the peritubular blood (B) carbon dioxide diffuses into the proximal convoluted tubule cell from peritubular capillary blood; undergoes a chemical reaction to form carbonic acid; dissociates into hydrogen and bicarbonate ions; the hydrogen ion diffuses into the glomerular filtrate of the proximal convoluted tubule (C) hydrogen ions diffuse out of the peritubular capillary blood, through extracellular fluid and into the filtrate of the proximal convoluted tubule (D) carbon dioxide diffuses into the proximal convoluted tubule cell from the glomerular filtrate; undergoes a chemical reacdtion to form carbonic acid; dissociates into hydrogen and bicarbonate ions; the hydrogen ions diffuse into the peritubular blood
