Circulatory System Flashcards
(30 cards)
its stimulus
stretch in arterial wall due to increase pressure in the blood
Baro
its stimuli is
decreased 02
increase C02
Chemo
its stimulus sympathetic stimulation of the heart
blood vessels also increase stimulation of adrenal medulla
Adrenal Medullary Mechanisms
its stimulus
reduced blood flow or reduced BP
Renin Angiotensin Aldosterone Mechanism
its stimulus
concentration of solutes in PLASMA INCREASE
ADH
its stimulus
INCREASED BP
Atrial Nauretic Hormone
Located in
Carotid Sinus
Walls of Aortic Arch
Walls of LArge Arteries
BAro
Located in
Carotid Bodies
Aortic Bodies
Chemo
located in kidney
ADH
located in
kidney and lungs
Renin Angiotensin Aldosterone
located in adrenal medulla
Adrenal Medullary Mech
located in the Heart
Atrial nauretic Hormone
Mechanisms that increseas BP?
Chemoreceptor
Adrenal Medullary
Renin Angiotensin Aldosterone
Anti Diuretic Hormone
MEchanisms that decreases or lowers BP?
Baroreceptors & Atrial nauretic Hormone
Response
INCREASE frequency delivered to the vasomotor and cardioregulatory in medulla ooblongatacauses to LOWER BP
Baro
Response
Increase frequency of AP causes to activate chemoreceptor
Chemoreptor
releases epinephrine and small amount of norephinephrine
Adrenal medullary
hypotalamus releases ADH or VAsopressin in Posterior Pituitary Gland
ADH
causes kidney to absorb mor water
ADH helps to maintain blood Volume and Blood Pressure
large amounts will cause vasoconstriction resulting to INCREASE BP
Promotes LOSS of Na+ and water in Urine
Atrial Nauretic
release from specialized cell in RA
average pressure in artery during 1 minute
Mean Arterial Pressure
-good indicator of perfussion than SBP
difference between systole and diastole
Pulse Pressure
measure of force blood exerts againts blood vessels walls
BP
blood pressure of the arteries fall to a minimun vallvue
Diastole
