To not waste your time watching this video When body temperature is too high blood vessels dilate to increase heat loss to surroundings When body temperature is too cold blood vessels contract to avoid heat loss to surrounds

@ellie-maesmith7628 3 года назад

Yes!!

I thought capillaries don’t have smooth muscle, just a single layer of epithelial cells. So how can vasoconstriction and vasodilation occur?

@SlipknoTXXIV 8 лет назад

I thought capillaries don't vasoconstrict or dilate, but the arterioles leading to them?

@5Youssif 7 лет назад

Thought small capillaries do not have smoooth muscles around them

@tomaszkowal5092 8 лет назад

I don't think that the factor for dilution or contraction of the capillaries is "hot out" or "cold out" but rather increasing or decreasing temperature of the body itself.

This lecture really help me understand vasodilation & vasoconstriction it's been a while since I've had any chemistry.

"because skin is pink" :/ weird comment when the majority of the world does not have pink skin

@anannyo2002 Год назад

Stfup niga🤣🤣🤣🤣🤣

@samdottori Год назад

I don't think he said it maliciously, I'd rather focus on the exam

Skin is pink. It gets darker the more melanin each ethnicity secretes. Also one important fact here, skin "appears" to be pink because of the blood underneath it. In reality skin is colorless; it is translucent.

@hungryhungryrhino1 5 лет назад

Ok I knew that vasodilation will allow you to lose heat. But how does it do that specifically? How is more blood in the blood vessel helps heat to be radiated to the surroundings?

"I am going to draw skin in pink, because skin is pink"...

@halloheimur Год назад

came looking for this comment, pretty fucked up

@chelsielynn759 3 года назад

"What would you do if it were getting too hot in your house?".... Me: turn the a/c up! ...."open the windows!" I forget people that don't live in Arizona actually open windows to let heat out.

@seasq Год назад

This is counterintuitive as someone living in Texas, but I just have to remember that it is. Lol

@happyvip6151 4 года назад

is this called convection then ?

@maipensapparot 6 лет назад

but seriously, this comment about pink skin kinda throws you off

@samarthdhole6346 6 лет назад

D. V. WORD, didn't expect that from khan academy

@nicolejohnson9493 5 лет назад

I'm sure he didn't mean it like that and I'm sure u kno that.

@stavshmueli6932 5 лет назад

Are you really going to complain about such benign comment? What a pathetic individual you must be that this remark actually caused you distress, knowing full well that he didn't intend it in any racist way. This is coming for a non-white person btw, just shame on you, really.
