Answer :

As a result, the right atrium's pressure rises, stimulating the atrial stretch receptors. These receptors then send a message to the medullary control centers, telling them to lower the heart's parasympathetic tone through the vagus nerve.

Stretch receptors in the heart's atria are engaged as blood volume increases, which leads to?

These receptors send a signal to the brain's hypothalamus when they see an increase in blood volume in the atria. This causes the atrial stretch, which causes the release of atrial natriuretic peptide (ANP), to occur.

What causes the release of atrial natriuretic peptide?

In reaction to the increased pressure brought on by a large blood volume, cells in the wall of the right atrium of the heart release atrial natriuretic peptide (ANP).
