CDC protect America from health, safety and security threats, both foreign and in the U.S whether diseases start at home or not
The correct answer is: Baroreceptors in the arteries send a signal to the brain that the blood pressure is low. The brain sends a chemical signal to the heart to increase its rate of pumping. This continues until the baroreceptors sense a normal blood pressure.
A negative feedback loop occurs in the body when something in the body has decreased in function, which could mean high or low, for example blood sugar, body temperature or in this in this case blood pressure. It then creates a feedback loop to tell that part of the body to regulate itself and return the body to a state of homeostasis (which is your optimal internal state). In a negative feedback loop the response of the regulating mechanism is opposite to the output of the event. So if blood pressure is low the negative feedback loop will tell the body to increase the pressure.
A positive feedback will result in more of a product: more prolactin, more contractions, or more clotting platelets.
Health leads a life of good strength and less illness. Which is a good thing, though work is required to gain health.
I hope that helped.
Humans tend to build things in the environment that shouldn't be there at all because it will affect the living things like animals and plants. Another thing that human causes is pollution, usually when they work in power plants they don't dispose the chemicals property and that can be dangerous to the water and the plants.
