When you take a close look at the circulative system, it looks like a big ball of wool that a kitten has gotten hold of, and worked it into one huge knotted mess. Actually the circulative scheme is in all probability a lot requiring little effort to sort out then that wool would be. Our popular cognition of the heart is, we know if it is not working right we may suffer a heart attack. That there are four chambers in the heart, and that there is a whole string of veins and arteries We don’t know a whole lot regarding these except, that if we cut an artery we could without apparent effort bleed to death. Another fact that is reasonably mutual to us, is we recognise that if we have too much fat in our blood, then cholesterol has something to do with it, and it is not good for us. That beauteous well sums up our noesis of the circulative system. Really when you stop to think when it comes to it, that’s a reasonable amount of knowledge. If we had just a few more details to our cognition it may drive a lot of us to think with regards to how it genuinely affects our entire bodies, and that by knowing what it needs, and why it needs sure things, we will be all the more likely to ascertain it gets it. Sometimes to exhaustively comprehend something it helps to paint a picture. So let me do something similar to that here ,and give you something that is easy to visualize. Picture a two lane highway. One is going North the other South. At the beginning of the highway going south is a hugh formulating plant (the heart). In this plant are four rooms (four chambers of the heart) that each develop a material, for the final product that this company makes(the enriched oxygen filled blood cells). This good product is pumped out into containers (arteries). These containers are now transported away from the plant (heart) down the highway(the blood flow) to respective stores along the way(body organs that need the enriched cells.) Now in the other direction coming down the North highway is containers (veins)coming back toward the plant. These containers are carrying waste materials (blood that needs to be re oxygenated) These are dropped off at the plant (heart) where it will be refurbished(re oxygenated) and then sent out once again in the good containers (arteries). This routine takes place over and over again continuously. This scenerio is only staged this way as a visualization, to plainly help you know how the circulative system works. If we wanted to, we could carry on with this visualization as to what takes place in the four rooms (chambers of the heart) in order to get the good product ready. Hopefully this has given you a little more understanding of how the system works and the importance of it . For example going back to our visualization, if one item were to break down then it would have a direct affect on all the other steps. This is incisively would occur in our bodies. |
