Is the Heart a muscle or Organ?

[wedge22]

I know its a muscle but many of my work colleagues disagree. What do you all think?

[Elmo]

it's both, well, the muscles around it pump the blood through it, but it's an organ cos you couldnt really live without it....

[iggy]

its both

[Alex]

A muscle is an organ. So is skin etc. An organ is an organised collection of tissues, which is an organised collection of cells. An organism is an organised collection of organs.

So yes, its both.

I reckon its a muscle cos try as I might, I just can't get a tune out of one....

It's a muscular organ, apparently.

The heart is a muscular organ located just to the left of the breast bone
(sternum). It is about the size of your fist, and this amazing muscle pumps
4300 gallons of blood a day. The heart has four chambers:

* Atria. The top two chambers that receive blood from the body
* or lungs.
* Ventricles. The bottom two chambers. The right ventricle pumps
* blood to the lungs to pick up oxygen, The left ventricle pumps blood to the rest of the body and is the strongest chamber.
* Valves. There are four valves in the heart that help to direct blood flow. As they open and close, the valves produce sounds that can be heard with a stethoscope.

That's cos you're more used to playing a blue-veined flute....allegedly.....so Vaul sez anyway....

[Tumble]

yes it's an organ - it just happens to made of very dense muscle tissue... the stomach, also an organ, is also made largely of muscle tissue.....

And he'd know how to play one would he?

ahh... so THAT'S why he calls you 'Teach'!

I'd go for both, isnt it surposed to be the most powerful muscle in the body. I rember when he did disection in bio, we stuck our finger through the venricals and made them look like superman capes on our hands. Ow the fun you can have withe a heart, its a childs best freind.

[Elmo]

the strongest muscle in ur body is actually your tongue

[Trippledence]

I think we should race them. Heart VS. Tougue, in a race, no FIGHT to the death!

[5lab]

both

[shelley bda]

The heart is a pump, muscles must be needed somewhere because it wouldn't be able to pump the blood around the body without muscle

What i do know is that we would be well and truly buggered without one

[Trippledence]

An organ can be made of muscle.

Whatever, Mr. Lets all be happy and freinds. In your twisted world theres equality and everything, leave me be!

[shiato storm]

it is an organ that is made of muscle. I study muscle for a job, I would therefore like to pose that the question itself is wrong not the answer...it is BOTH muscle and organ.
now; define organ.
