Which of the following waste products excreted in urine is the result of metabolic reactions in muscle cells
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?
the loop of Henle
Which of the following is not normally a component of the glomerular filtrate?
Glomerular filtrate consists primarily of water, excess salts (sodium ions), glucose, and a waste product of the body called urea.
Most reabsorption of water and nutrients from the glomerular filtrate occurs in the
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
Which of the following is not reabsorbed into the blood by the process of tubular reabsorption?
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
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
What is reabsorbed?
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?
What is not reabsorbed into the blood by the process of tubular reabsorption?
bicarbonate (says it seems to but isn't)
Aldosterone stimulates sodium reabsorption and potassium secretion in
the distal convoluted tubule and the cortical collecting duct.
Substance X has a clearance greater than zero but less than that of inulin. What can you conclude about substance X?
It is filtered and partially reabsorbed.
What is true about the renal pyramids?
They are located in the medula.
They contain collecting ducts.
They empty urine into the calycees
The ability of the kidneys to remove molecules from the blood plasma by excreting them in the urine. The process of reabsorption decreases renal clearance, while the process of secretion increases renal clearance
