hi everyone! my question is about starling's law... i just don't get it!! i have a whole bunch of definitions for it, but i am still struggling to understand it!!! can someone please explain it to me in the most layman of layman terms!! thanks...
If you want to understand about starlings law of heart contraction, think of a thick rubber balloon. Fill that balloon up with a little water so that it stretches just a little. When you release the top, a little water will come out with mild force. Now think of that same balloon and fill it up until it is stretched to it's max. Now when you release the top, lots of water comes out and with great force. This is starlings law of heart contraction. The more blood return to the heart (streching it) the greater the contraction.
we just had lab on saturday and our professor did an amazing job explaining it as well. it didn't help that our regular biology teacher was confusing the law of the capillaries with the law of heart contraction either!! i didn't even realise they were two different things until abefrohman pointed it out!!
