RAAA what is this? |
four hormones that increase blood pressure. |
|
RAAA what are they? |
Renin. angiotensin II. ADH. Aldosterone. |
|
this hormone decreases blood pressure |
Atrial natriuretic peptide. |
|
What are the hormones that are not part of the RAAA system |
Atrial natriuretic peptide Epinephrine norepinephrine. |
|
Angiotensin II is stimulated by this |
low blood pressure. |
|
This is the most important hormone |
angiotensin II |
|
This is the sensor for angiotensin II |
special kidney cells secrete renin. |
|
Renin does this |
converts Angiotensinogen to Angiotensin I |
|
Angiotensinogen comes from here |
Liver |
|
Angiotensinogen is activated to angiontensin II by this |
ACE. Angiotensin converting Enzyme |
|
ACE comes from here |
the lungs. |
|
Angiotensin II does this |
Widespread vasoconstriction Stimulates adrenal cortex to secrete aldosterone Stimulates posterior pituitary to secrete ADH |
|
Widespread vasoconstriction does this |
increases blood pressure |
|
ACE inhibitors are used for this |
high blood pressure/ chronic hypertension. |
|
ADH is stimulated by this |
Low BP and dehydration |
|
this is the ADH sensor |
osmoreceptors in the hypothalamus |
|
osmoreceptors do this |
sense blood osmolarity. |
|
osmoreceptors are found here |
hypothalamus |
|
ADH is secreted from her into here |
Hypothalamus to the posterior pituitary |
|
The control center for low BP and dehydration with is this |
hypothalamus secretes ADH into the posterior pituitary |
|
ADH is called this |
anti-diuretic hormone |
|
the effector for low BP and dehydration |
ADH acts on the kidney tubule to reabsorb water from the DCT and CD which increase blood volume to increase Blood pressure. |
|
This is DCT, and it is located here
|
Distal convulating tubule in the kidney tubule |
|
this is CD |
Collecting duct in the kidney tubule. |
|
Aldosterone is stimulated by this |
low BP |
|
This is the sensor for Aldosterone |
Osmoreceptors in the hypothalamus |
|
this hormone is release for aldosterone |
CRH |
|
CRH is this |
corticotropin-releasing hormone |
|
the control center for low bp in aldosterone is this |
CRH stimulates ACTH release from the anterior pituitary. ACTH stimulates the adrenal cortex to release aldosterone. |
|
ACTH is this |
adrenocorticotropic hormone. |
|
aldosterone comes from here |
adrenal cortex via stimulation by ACTH. |
|
The effector for low BP with regards to aldosterone is this |
aldosterone acts on kidney tubule to reabsorb sodium and water from the DCT and CD which increase blood volume to increase BP. |
|
Aldosterone and ADH are different in this way with regards to effect |
ADH only does reabsorbs water Aldosterone reabsorb sodium and water. |
|
Aldosterone and ADH are the same in this way with regards to effect |
both act on the kidney tubules to reabsorb things in the DCT and CD which increase blood volume which increase blood pressure. |
|
an increase in blood volume does this |
increase blood pressure |
|
Atrial Natriuretic peptide is stimulated by this |
high BP |
|
The sensor for high blood pressure is this |
atria sense blood pressure |
|
Atrial natriuretic peptide is secreted from this |
the heart, the atria to be exact |
|
ANP is this |
Atrial natriuretic peptide |
|
Atrial natriuretic effectors are this |
blocks renin (angiotensin) blocks aldosterone which decrease sodium and water resabsorption to decrease blood pressure blocks ADH widespread vasodilation. |
|
this hormone blocks these three things |
atrial natriuretic peptide renin aldosterone ADH |
|
Atrial natriuretic peptide does this |
decreases BP |
|
blocking Aldosterone would do this |
decrease sodium and water reabsorption which decrease blood volume and decrease blood pressure. |
|
adrenal cortex secretes this |
aldosterone |
|
adrenal medulla secretes this |
epinephrine and norepinephrine |
|
epinephrine and norepinephrine are stimulated by this |
any stimulation of the sympathetic nervous system (stress, exercise) |
|
epinephrine and norepinephrine do this |
vasodilation of vessels in the heart and muscles via B receptors. vasoconstriction of vessels in other tissues via a receptors which increases blood pressure. |
|
Beta receptors do this |
vasodilation vessels. as in heart and skeletal muscle from EPI NE release. |
|
Alpha receptors do this |
Constriction of vessels. as in other tissues via EPI and NE. |
|
Alpha receptors would do this to BP |
increase BP by constricting repro, digestive, urinary vessels. |
