Hormonal Regulators Of BP Flashcards
causing vasoconstriction, stimulating thirst, decreasing urine formation are ways that the hormone ___________ increases blood pressure
Angiotensin 2
____________ helps maintain blood volume and pressure, released from adrenal cortex, triggered by Angiotensin II and several other stimuli
aldosterone
_________ increases absorption of water in the kidneys and decreases urine output.
aldosterone
released from the posterior pituitary this hormone helps maintain and elevate blood pressure
antidiuretic hormone
this hormone is also known as vasopressin because in large amounts it causes vasoconstriction it also stimulates the thirst Center and increases water absorption
antidiuretic hormone
what are hormonal Regulators of blood pressure
Angiotensin 2 antidiuretic hormone antidiuretic hormone aldosterone atrial natriuretic peptide norepinephrine epinephrine
what happens in the renin-angiotensin system?
liver- angiotensinogen
kidney- renin- converts angiotensinogen to AG 1
AG 1 converted to AG 2 be ACE
ACE released by capillary walls ESP. in lungs
atrial natriuretic peptide does what to blood pressure?
decreases blood pressure
antidiuretic hormone does what to blood pressure?
how to maintain and elevate blood pressure
this hormone is released from atria when walls are stretched by blood volume, simulates vasodilation comma increased urine output
atrial natriuretic peptide
sphygmomanometer is used to measure?
blood pressure
the top number on a blood pressure score is?
systolic pressure, bottom number diastolic pressure
__________ chronically elevated blood pressure systolic 140, diastolic 90
hypertension
atherosclerosis may be more likely, May 2nd arterial walls ( arteriosclerosis), may cause heart failure: __________
hypertension
__________: chronically low blood pressure symptoms of fatigue dizziness and fainting. systolic blood pressure less than 90, diastolic blood pressure less than 60
hypertension
hey blood pressure at or above 140 systolic and 90 diastolic would be considered?
hypertension
a blood pressure at or below 90 systolic and 60 diastolic would be considered?
hypertension
transient drop in blood pressure after standing causes dizziness lightheadedness and fainting
orthostatic hypotension
how does blood flow change during exercise?
heart rate goes up blood flow goes up what does remove from Venus reservoirs, blood is redistributed toward the active tissues. blood goes towards the skin to dissipate Heat period last flood abdomen kidneys
describe structures blood flows through from right atrium to pulmonary arterioles
1) right atrium
2) right ventricle
3) pulmonary trunk
4) pulmonary arteries
5) pulmonary arterioles to capillaries
describe structures blood flows through from pulmonary venules to the aorta
1) pulmonary venules
2) pulmonary veins
3) left atrium
4) left ventricle
5) aorta
the right subclavian and right common carotid artery Branch off of the?
brachial cephalic artery
what are the three branches of the aortic Arch
brachial cephalic, left common carotid, left subclavian
what two major arteries Branch off of the abdominal aorta?
left common iliac, right common iliac
