If the urinary excretion rate of a drug such as penicillin is greater than the rate at which it is filtered at the glomerulus, how else is it getting into the urine?

tubular secretion

Which of the following hormones increases reabsorption of sodium in the kidney? 1. angiotensin II 2. aldosterone 3. atrial natriuretic peptide

1 and 2 are correct

Which INCREASES GFR?

action of atrial natriuretic peptide (ANP) on mesangial cells.

The gastrocolic reflex

initiates mass peristalsis.

As you smell food, your mouth begins to water and your stomach rumbles. This signals the beginning of the gastric phase of digestion.

False

Filtration through the glomerular capillaries is much greater than that seen in capillaries elsewhere in the body because the afferent arteriole in the glomerulus is smaller than the efferent arteriole.

False
