There is also a valve controlling the flow of blood out of each of your ventricles. The valves are designed to keep blood flowing forward only.

Explain the negative feedback loop between baroreceptors, the cardiovascular (CV) center, and the heart. Address: dropping blood
marysya [2.9K]

Answer with Explanation:

Homeostasis<u> allows an organism to regulate its internal condition in order to adapt to a changing environment.</u> In order to maintain this, the positive and negative feedback mechanisms (loops) remain essential <em>when it comes to physiological processes that are deemed complicated.</em>

<em>Let's talk about the "Negative Feedback Loop."</em>

  • The "baroreceptors" are sensors in the blood vessels.
  • For example, when the body's temperature changes, the body's initial reaction is to return to its normal level. So, it goes the same way with blood pressure. When the baroreceptors sense an increase or a decrease in blood pressure, it communicates with the hypothalamus by sending a signal. Then, the hypothalamus sends a message to the organs that are responsible for returning the blood pressure to normal level. These organs are the heart, kidneys and blood vessels. So, if a person experiences a "dropping blood pressure," heart stimulation follows (causing an increase heart rate) due to hormonal vessel constriction. This also allows the kidney to retain more water, thereby increasing the blood pressure.

This is how all these elements work together to achieve homeostasis.
