  • Sorry I didn't see your message earlier. So as noted below, while high volume will decrease renin secretion indirectly by increased stretch, B1 leads directly to renin secretion.

  • From Harrison's Internal Medicine, 17th edition, Chapter 241 Hypertensive Vascular Disease, subsection Renin-Angiotensin-Aldosterone (Page 1551) it states: "There are three primary stimuli for renin secretion: (1) decreased NaCl in the thick ascending limb of the loop of Henle (macula densa mechanism), (2) decreased pressure or stretch within the renal afferent arteriole (baroreceptor mechanism), and (3) sympathetic nervous system stimulation of renin-secreting cells via B1 adrenoreceptors."

  • Take your pants off too?

  • Alpha1 --> Dcreases RENIN

    B1 --> Increases RENIN

    Alpha2 --> Decreases INSULIN release

    B2 --> Increases INSULIN release

  • @iagaku you might wanna double check that B1 receptors DO increase renin release (Sympathetic nervous system activity, which also controls blood pressure, acting through the beta1 adrenergic receptors). 

  • Great video, but just to correct a little mistake. Beta 1 receptors do not INCREASE renin secretion by the kidneys, they actually DECREASE it, this is because B1 receptors exert positive chronotropic and inotropic effects on the heart thereby causing high volume states (renin secretion is favored by a low volume state).

    Great video anyway.

  • that is so cool !! thanks ..U made it v.easy to remember ..

  • hahaha i love thissss!!!!!!
