Human Physiology of the Kidney-Questions and Answers Graded A+ The urinary system includes - ANSWER-kidneys, ureters, urinary bladder, urethra The urinary system doesn't include: - ANSWER-adrenal glands Which of the following waste products excreted in urine is the result of metabolic reactions in muscle cells - ANSWER-creatinine What is normally excreted in the urine? - ANSWER-vitamins, drugs, excess ions, uric acid, urea, creatinine Which of the following is not normally excreted in urine? - ANSWER-protein, glucose When urine leaves the kidney, it enters the - ANSWER-urinary bladder Descending limb and ascending limb are best associated with - ANSWER-the loop of Henle As fluid passes through a nephron it undergoes modification by the cells lining the tubule. In which of the following locations does this modification of filtrate not occur? - ANSWER-the loop of Henle Which of the following is not normally a component of the glomerular filtrate? - ANSWER-protein Glomerular filtrate consists primarily of water, excess salts (sodium ions), glucose, and a waste product of the body called urea. Which of the following is not normally a component of the glomerular filtrate? - ANSWER-red blood cells Most reabsorption of water and nutrients from the glomerular filtrate occurs in the - ANSWER-Proximal tubule or proximal convoluted tubule Which of the following processes involved in the formation of urine is especially important in the excretion of toxic substances and drugs - ANSWER-tubular secretion Which of the following is not reabsorbed into the blood by the process of tubular reabsorption? - ANSWER-Creatinine is not reabsorbed at all as it is too large. Bicarbonates seem to be reabsorbed, but it isn't. Bicarbonate balances ph. Reabsorption is sensitive to PH, so a drugs which polar will not be reabsorbed ADH - ANSWER-causes the cells of the collecting ducts to be more more permeable to water, thereby increasing reabsorption of water into tissue fluids and blood stream Glucose - ANSWER-Filtered, and reabsorbed, but not secreted What is reabsorbed? - ANSWER-Water and filtered solutes which includes chloride ions, sodium ions, potassium, monosaccharides (glucose). uric acid, and 40-60% urea is reabsorbed. Most amino acits are reabsorbed?
