Which of the following is true about inulin?
All inulin is either filtered by the glomerulus or secreted by the peritubular capillaries
Most inulin filtered by the glomerulus is reabsorbed by the peritubular capillaries
Inulin is removed from the peritubular capillaries by tubular secretion
Some inulin filtered by the glomerulus is reabsorbed by the peritubular capillaries
...
Tubular secretion occurs when?
Filtered fluid passes from the nephron tubules to the efferent arteriole
Filtered fluid leaves the glomerulus and enters the glomerulus capsule
waste products from blood pass from the peritubular capillaries to the nephron tubules
Filtered fluid passes from the nephron tubules to the peritubular capillaries
Filtered fluid leaves the afferent arteriole and enters the glomerulus capsule
...

they are against the anterior wall of the abdominal cavity
...
If the transport maximum of glucose is 320 mg/minute, what will happen if the tubular fluid contains 350 mg/minute of glucose?
glucose transport will increase to 350mg/minute
glucose will be excreted into the urine
excess glucose will be degraded by mesangial cells
GFR will increase to accommodate this rate
