I wouldn't accept this statement as exact - peripheral resistance changes can lead to chronic high blood pressure without the need for other central changes (though both usually exist side by side)
are you talking about the renin-angiotensin system? It is a major player in blood pressure control and affected in many (though not all) cases of chronic hypertension. I can list more specifics if needed...
Peripheral vasoconstriction is central to acute blood pressure control. It's not important at all in chronic control, although things that change it are. The RAS contributes, but I'm looking for a step in between the RAS (or RAAS, if you like) and hypertension.
Well, it hasn't been 72 hours, but it's time for a new question anyway.
The answer to the old one was altered pressure natriuresis in the kidney, or tubular reabsorption, depending on how accurate you wanted to be.

What makes you think that? There's plenty of us here who are not biologists of any kind, which is why we don't even try to answer things like what you posted. That doesn't make us uninterested. We're just waiting for the right questions.

Yeah, Physics only for me Or random guesses. But in this case I don't even know the name of a single protien, so I can't guess at all.

I hadn't forgotten about the rest of you.
In fact, I'll change the question to something that people might know:
How many mmHg to one KPa?

if you remember basic high school chem, you oughta know this one:
What is a ketone, what is its structural formula, and give an example of one.

A ketone is an organic compound with a carbonyl functional group, of the form R'COR. An example would be acetone.

Well, thats pretty damned spot-on. Its actually almost like the wiki article...
Did you wiki that? ~.~
Anyways, if you didn't, you're up.

Nah, I remember my chemistry textbook.
Why is the arbitrary constant of integration necessary?

Its there to represent the infinite number of antiderivatives, and also to make sure that you cannot prove for instance, that 1 = 0.
To put it in (perhaps) simpler words you could say that since any constant factor becomes 0 when you differentiate a term, all terms that only differ in their constant factor will be mapped to the same derivative. When you then integrate that derivative to find the term it originated from, there's no way of knowing which of all those terms with different constant factors is the correct one - it could be any of them. Thus the arbitrary constant factor introduced.

Stickciv was right, but the rules are a harsh mistress. It's your turn.To put it in (perhaps) simpler words you could say that since any constant factor becomes 0 when you differentiate a term, all terms that only differ in their constant factor will be mapped to the same derivative.
