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

Which of the following is true concerning the location of the kidneys?

the right kidney is usually higher than the left one

they are located behind the parallel peritoneum

their upper borders are about at the level of the third lumbar vertebra

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
