What is Blood Pressure
Pressure used to circulate blood through the body.
What does the body do to compensate for Low BP
- Sympathetic Response
- Increase heart rate
- Vasoconstriction
- Increase heart contractility
What does the body do to compensate during High BP
- Activate parasympathetic
- HR will decrease
- Blood vessels will Dilate
- Decrease in cardiac contractility
Renine
Enzym released by the kidneys in response to low bp
Angiotensin converting enzyme ( ACE )
Controls blood pressure by regulating the volume of fluids in the body
converts angiotensin 1 hormone into the angiotensin 2 hormone which is a vasoconstrictor.
Angiotensin
Peptide hormone that causes vasoconstriction and increase in blood pressure.
ADH
Anti-Diuretic Hormone that comes from the posterior pituitary
