Is blood pressure regulated by positive or negative feedback?
Hemiheaddave
Aldosterone is both responsible for absorption of sodium and excretion of potassium.
If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood.
If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-

Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
What is an example of negative feedback mechanisms?
Control of blood pressure.
Is control of blood glucose levels a negative feedback?
If high blood pressure is at play then a negative feedback system would reverse this. Through this negative feedback the stimulus of increased pressure is reversed or decreased by decreasing heart rate which decreases the blood pressure. If low blood pressure is at play the negative feedback system would also be appropriate because your body needs to reverse this stimulus. Your heart rate would increase to increase blood pressure. NOTE: Positive Feedback system enhances or further intensifies the stimulus so we would not want that for blood pressure. This is seen for birth contractions. You want to intensify contractions to enable the baby to get out of the canal. However, usually you need some external event to turn off the positive feedback or it could be fatal. In this case the baby is born so that stops the contractions.
Is peer pressure always a negative or bad thing?
There are positive peer pressure and there are negative peer pressure. In most cases peer pressure is positive, this happens hen it leads to a positive attitude in a child.
Why the slope of temperature versus pressure graph is positive in some cases and negative in other cases?
If the pressure is increasing then the slope is positive. If the pressure is decreasing then the slope is negative.
The patient has arteriosclerosis which results in increased peripheral resistance to blood flow which worsens the hypertension Is this a negative or positive feedback.Explain?
Its a negative feedback,because the smaller the lumen , the higher the blood pressure because of the deposit in the vessel thus causing the resistance.
What are the different kinds of peer pressure?
yes there are. there is positive peer pressure, and negative peer pressure. going and doing drugs is negative peer pressure, whereas going to do something fun and exciting is positive peer pressure.
Control mechanisms that lower blood pressure in response to rapid rise in blood pressure are called?
Negative feedback mechanisms
What are the nature of peer pressure?
Peer pressure is either negative or positive in nature.
The oxyhemoglobin dissociation curve represents a negative feedback mechanism?
A negative feedback mechanism is a system to return a disruption in homeostasis back to homeostasis.A positive feedback mechanism is a system to reinforce or perpetuate a disruption in homeostasis.The oxyhemoglobin dissociation curve represents the Partial pressure in oxygen that will be saturated in the amount of hemoglobin.This curve represents a positive feedback because the binding of Oxygen to hemoglobin facilitates more binding of oxygen to hemoglobin (you can see this in the rapid rise in saturation from 10-40 mm Hg) until it reaches 60 mm Hg where it is somewhat completely saturated
What is the difference between positive feedback control system negative feedback control system?
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or interest generation among the clients) and a negative feedback means a bad response (unhappy clients, criticism and the like ).
