Positive feedback loops are common in pathophysiological perpetuation of disease. For example, arteriosclerotic hypertension results in positive feedback mechanisms thatenhance and propagate the initial step in the chain of events, which is hypertension.

Which Site is the major determinant of peripheral resistance?
cardiac output and heart rate
How will blood peripheral resistance change as a result of increased hematocrit?
An increased hematocrit indicates a higher ratio of RBC's in the blood. Any increase in cellular elements, whether WBC's, RBC's or platelets, will act to essentially mechanically "thicken" the blood viscosity, sort of like using a heavier grade oil in your car. Increased blood viscosity will increase peripheral resistance, as it becomes harder for the heart to circulate the thicker blood, especially in the capillaries.
Explain relationship between the diameter of vessels and the velocity of blood?
describe and explain the relationship between the diameter of vessels and the velocity of blood
How does the development of MSRA illustrate how adaptation and natural selection can lead to the development of new strains of microorganisms?
MRSA developed as its ancestors were stressed and mostly killed by antibiotics. Some few individuals had a resistance to these antibiotics and survived. These resistant individuals then had offspring passing on this resistance. We can see survival of the fittest at work and its results because bacteria reproduce so rapidly.
What is human body resistance to electricity if skin is wet?
human body resistance to electricity when skin is wet is 1,000 ohm and when skin is dry its resistance is 100ohm
The client was admitted to the hospital with hypertension The development of arteriosclerosis has increased peripheral resistance to blood flow worsening his hypertension This is an example of what?
oh my gosh i hope someone answers this question soon, i am worried about that client.
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 is the explanation for the term total peripheral resistance?
Total peripheral resistance is the sum of the resistance of all peripheral vasculature in the systemic circulation.
What is main site of peripheral resistance?
arterioles offer maximum peripheral resistance .Skin and skeletal muscle blood vessels represent most imp. site of peripheral resistance.
Does exercise Change in cardiac output or in peripheral resistance?
Both, peripheral resistance decreases and cardiac output increases.
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
Does dehydration increase peripheral resistance?
yes
What is blood flow directly proportional to?
Peripheral resistance
What center in the medulla can alter peripheral resistance?
Hypothalamus
Decreased peripheral resistance to blood flow?
Anemia
What is the event primarily responsible for peripheral resistance?
Constriction of arterioles
How does blood viscosity affect blood flow?
Peripheral resistance
