the right side of the heart?
the human heart is on the left side of the body. Is it the "right" side? Why is it on the left side? Oh, and please don't say it's becauseof evolution.

Its a muscle pumping blood.. giving it oxygen.. bring it in and send it out... A vain here for this, and artory there for that... haha stuff like that ...

You are quite right turkey.
I've not long had a heart procedure done & had six tubes in my groins going up to my heart, (3 in each).
After 24 hours, the tubes were taken out. One of the veins in my left groin was plugged as it was the Arterial vein (main artery). I am told this will dissolve over the next three months.You can just imagine the amount of blood loss if they hadn't plugged it!!!!
thank you all for the answers but maybe we will have to involve the evolution... hmm...
long long time ago evolution had to make a decision, and my question is: why did it chose "left"? Why isn't the heart symetric?
I know how the heart works, i know where it is situated in our bodies, but what i would like to know is: why is the heart like it is?
I hope someone can understand what i try to say : )
so in effect, if we start at the left side of your heart..the blood comes in from the lungs in the pulmonary artery which has been oxygenated so its ncie and juicy for your body..this leaves the left ventricle via the aorta and travels round the body till it reaches the vena cava (inferior and superior) which enter in the right atrium of the heart. this blood is now oxygenated so no use to your cells and muscles etc..so it requires reoxygenating... off it goes in the pulmonary vein to the lungs and the cycle starts all over again
the point i am trying to not so eloquently make is that if the heart was not like it is, out legs would probably slowly die from lack of blood/oxygen and that'd be pretty shoddy!
think of it like squeezing toothpaste out of tube, if you hold the tube right next to the brush, you don't need a lot of force to get to the brush... thats like the right side of the heart and the lungs..
if you hold the brush further away you need to apply more force to get to travel a greater distance..
poor analogy but i'm cleaning my teeth and its all i could come up with!
