a vasopressor substance produced when renin is released by the kidneys is called:
physiologically INACTIVE for or angiotensin
ACTIVE form of angiotensin
reduces blood pressure, causes vasodilation is called:
angiotensin converting enzyme (ACE) is also a angiotensin II blockers
angiotensin II stimulates sodium reabsorption, causes vasoconstriction and stimulates:

typical signs and symptoms of CHF
- adventitious b/s ins-exp
- red exercise tolerance
- cool skin
typical signs and symptoms of Cor Pulmonale

lab findings for cor pulmonale
- increased hematocrit
- increased hemoglobin
lab findings for CHF
