- The segmental arteries branch to form the ______ arteries that travel through the renal columns.
- Dilation of respiratory airways, release of adrenal cortex hormones, and promotion of inflammation are just some of the effects of paracrine substances called
- Water reabsorption regulated by ADH near the end of the tubule is _____ of Na+ reabsorption
- Sympathetic stimulation can result in a(n) ______ in GFR through vasoconstriction.
- What acts as the link between a nonsteroid hormone and its second messenger, cAMP?
- Some substances are not normal components of urine because they are completely reabsorbed. Choose the substances that satisfy this requirement under healthy conditions.
- Adenylate cyclase is an enzyme that catalyzes the conversion of ______ into ______.
- Downregulation often occurs in target cells after a prolonged presence of a hormone. This involves a(n) ______ in the number of receptors in a target cell.
- When activated by a hormone, some target cells produce ______ which then induce the effects of the hormone stimulation within the cell.
- The movement of water out of the proximal convoluted tubule follows Na+ by osmosis and is referred to as____ ______ ____-
- The pancreas is an example of an endocrine gland that secretes hormones in response to ______.
- When we are dehydrated, ADH binds to receptors to increase the migration of vesicles containing ______ to the membrane of the principal cells.
- What is an example of a commonly used second messenger that may be activated by nonsteroid hormones?
- True or false: Aldosterone increases the number of Na+ pumps and channels and thus decreases both Na+ and water reabsorption.
