心房组织中有一种具有分泌和贮存作用的颗粒,这些颗粒含有一种激素多肽,是由151个氨基酸组成的激素前体。它进一步分解为更小的肽,其中的一种取名为α-利钠多肽(即心钠素),由28个氨基酸组成,具有很强的利钠、利尿和扩张血管的作用,可以协助维持水钠平衡和调节血管紧张素原-血管紧张素-醛固酮系统。 Atrial tissue has a secretion and storage of particles, these particles contain a hormone peptide, is a 151 amino acid hormone precursor. It is further broken down into smaller peptides, one of which is named alpha-natriuretic peptide (aka ANP), which consists of 28 amino acids and has strong sodium, diuretic and dilated blood vessels that can assist Maintains water-sodium balance and modulates angiotensinogen-angiotensin-aldosterone system.
