, How does the RAAS (Renin- A drop in blood pressure is sensed by the
Angiotensin-Aldosterone kidneys by low perfusion, which in turn begins
System) result in increased to secrete renin. Renin then triggers the liver to
blood volume and increased produce angiotensinogen, which is converted to
blood pressure? Angiotensin I in the lungs and then angiotensin
II by the enzyme Angiotensin-converting
enzyme (ACE). Angiotensin II stimulates
peripheral arterial vasoconstriction which raises
BP. Angiotensin II is also stimulating the
adrenal gland to release aldosterone, which
acts to increase sodium and water reabsorption
increasing blood volume, while also increased
potassium secretion in urine.
How can hyperkalemia Normal levels of potassium are between 3.5
lead to cardiac arrest? and 5.2 mEq/dL. Hyperkalemia refers to
potassium levels higher that 5.2 mEq/dL. A
major function of potassium is to conduct
nerve impulses in muscles. Too low and
muscle weakness occurs and too much can
cause muscle spasms. This is especially
dangerous in the heart muscle and an
irregular heartbeat can cause a heart attack
The body uses the Protein Proteins contain many acidic and basic group
Buffering System, Phosphate that can be affected by pH changes. Any
Buffering System, and Carbonic increase or decrease in blood pH can alter the
Acid-Bicarbonate structure of the protein (denature), thereby
System to regulate and maintain affecting its function as well
homeostatic pH, what is the
consequence of a pH
imbalance?
