  2. Baroreflex - Wikipedia

    en.wikipedia.org/wiki/Baroreflex

    When blood pressure rises, the carotid and aortic sinuses are distended further, resulting in increased stretch and, therefore, a greater degree of activation of the baroreceptors. At normal resting blood pressures, many baroreceptors are actively reporting blood pressure information and the baroreflex is actively modulating autonomic activity.

  3. Vasopressin - Wikipedia

    en.wikipedia.org/wiki/Vasopressin

    Bainbridge reflex: In response to stretching of the right atrium wall, heart rate increases, lowering venous blood pressure. Baroreflex: When the stretch receptors in the aortic arch and carotid sinus increase, the blood pressure is considered to be elevated and the heart rate decreases to lower blood pressure.

  4. Angiotensin - Wikipedia

    en.wikipedia.org/wiki/Angiotensin

    Angiotensin is a peptide hormone that causes vasoconstriction and an increase in blood pressure. It is part of the renin–angiotensin system, which regulates blood pressure. Angiotensin also stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys. An oligopeptide, angiotensin is a hormone and a ...

    en.wikipedia.org/wiki/Renin–angiotensin_system

    Baroreflex: When the stretch receptors in the aortic arch and carotid sinus increase, the blood pressure is considered to be elevated and the heart rate decreases to lower blood pressure. Antidiuretic hormone: The hypothalamus detects the extracellular fluid hyperosmolality and the posterior pituitary gland secretes antidiuretic hormone to ...

  6. Baroreceptor - Wikipedia

    en.wikipedia.org/wiki/Baroreceptor

    The blood volume determines the mean pressure throughout the system, in particular in the venous side where most of the blood is held. The low-pressure baroreceptors have both circulatory and renal effects; they produce changes in hormone secretion, resulting in profound effects on the retention of salt and water ; they also influence intake of ...

    en.wikipedia.org/wiki/Atrial_natriuretic_peptide

    Baroreflex: When the stretch receptors in the aortic arch and carotid sinus increase, the blood pressure is considered to be elevated and the heart rate decreases to lower blood pressure. Antidiuretic hormone: The hypothalamus detects the extracellular fluid hyperosmolality and the posterior pituitary gland secretes antidiuretic hormone to ...

  8. Natriuretic peptide - Wikipedia

    en.wikipedia.org/wiki/Natriuretic_peptide

    B-type natriuretic peptide (BNP) and its pro hormone NT-proBNP are especially useful in diagnosing heart failure, as their levels in the blood increase along with the severity of the condition. [3] Rapid testing of BNP and NT-proBNP can also help distinguish between shortness of breath due to heart and lung-related causes.

  9. Brain natriuretic peptide 32 - Wikipedia

    en.wikipedia.org/wiki/Brain_natriuretic_peptide_32

    Brain natriuretic peptide (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. [5] BNP is one of the three natriuretic peptides, in addition to atrial natriuretic peptide and C-type natriuretic peptide ( CNP). [6]
