What do cellular respiration and fermentation have in common? They both harvest energy from sugars. They both end up with pyruvic acid. They both occur in the mitochondria. They both require oxygen to occur.

Hey :)

Vasodilation is where blood vessels widen

It results from relaxation of muscle cells within blood vessel walls

The process is essentially the opposite of vasoconstriction, which is the narrowing of blood vessels

When vessels widen, blood flow is increased

This in turn decreases blood pressure

Hope this helps :)
