Front Back
hormone secreted by the adrenal cortex that increases sodium reabsorption in the distal tubule of the kidney
Aldosterone
chemical released in response to falling blood pressure that causes vasoconstriction and release of aldosterone
Angiotensin II
enzyme responsible for converting angiotensin I to angiotensin II
ACE Angiotensin-converting enzyme
hormone produced by the hypothalamus and secreted by the posterior pituitary that stimulates the kidneys to conserve water
ADH Antidiuretic Hormone
nerves located in the walls of the atria, aortic arch, vena cava, and carotid sinus that sense changes in blood pressure
Baroreceptors

Benign prostatic hyperplasia (BPH)
drug that blocks the flow of calcium ions into myocardial cells
Calcium Channel Blocker
amount of blood pumped by a ventricle in 1 minute
Cardiac output
nerves located in the aortic arch and carotid sinus that sense changes in oxygen content, pH, or carbon dioxide levels in the blood
Chemoreceptors
procedure in which the dose of cardiac glycoside is gradually increased until tissues become saturated with the drug, and the symptoms of heart failure diminish
Digitilization
portion of the nephron that collects filtrate from the loop of Henle
Distal tubule
substance that increases urine output
Diuretic
charged substances in the blood such as sodium, potassium, calcium, chloride, and phosphate
Electrolytes
the inner lining of a blood vessel
Endothelium
high blood pressure
Hypertension
portion of the nephron between the proximal and distal tubules
Loop of Henle
fall in blood pressure that occurs when changing position from recumbent to upright
Orthostatic Hypotension
the amount of friction encountered by blood as it travels through the vessels
Peripheral resistance
temporary increase in heart rate that occurs when blood pressure falls
Reflex tachycardia
series of enzymatic steps by which the body raises blood pressure
