2. The Juxtaglomerular Apparatus is a(n)
composed of macula densa which are specialized Endocrine structure
epithelial cells in the Distal Convoluted Tubule
(DCT)
3. If decreased blood pressure is sensed by the How Distal Convoluted
Juxta-
glomerular ( JG) cells, the JG cells release the hormone Tubule regulates blood
pres-
renin, which activates angiotensin (also sure and volume
hormone). Angiotensin causes vasoconstriction
and secretion of aldosterone (mineralocorticoid
hormone) by the adrenal cortex.
4. Angiotensin causes: Vasoconstriction; and
secre- tion of
aldosterone (miner-
alocorticoid hormone) by
the adrenal cortex
5. Aldosterone causes DCT cells: Increase Sodium

both are returned to the
blood which increases
