Neural and Hormonal Regulation of Cardiovascular System

What is the role of baroreceptors in the cardiovascular system?

Detect changes in blood pressure and send signals to the medulla

Which mechanism is responsible for immediate to long-term regulation of systemic blood pressure?

Humoral control mechanism

In case neural control mechanisms are insufficient due to excessive blood loss, which system comes into play to help regulate blood pressure?

RAAS (Renin-Angiotensin-Aldosterone System)
