you are just awesome... i always come back to your videos when i need a refresher before an exam.

Perfect.

If B1 constricts blood vessels w/ angiotensin, and B2 relaxes blood vessels, then why doesn't your body melt when a bear starts at you from the forest?

@WellConditionedChimp u make me think yeah how can constrict and relaxation of blood vessel occur at the same time???we r talking about sympathetic action rite??

[WellConditionedChimp]

@ezmeeremiral after some thought, I think that the receptors act on different parts of the body. During times of stress, more blood to the muscles would be advantageous, but the same could not be said for the skin. They do not act at cross purposes. Do you catch my drift?

[ezmeeremiral]

@WellConditionedChimp yeah thank you..actually i found the same answer when i google...but thanks for the explaination .:)

The camera could have been put on a tripod to avoid the shakey vision but it did help me though remember what beta1 receptors are for. Thanks a lot guys!

@goodiesong a comment filter would have been even nicer so i wouldn't have to read you incessant girl like bitching about the video quality. yea, fuck off.

Okay, so how does the butterfly relate expanding?

@seonz66

not sure really maybe its to do with the fact that butterflys flap wings 'expand' the lungs expand and that what this B2 helps with.

I don't know shot in the dark lol
