Overview of the Human Circulatory System
When you take a close look at the circulatory system, it looks like a big ball of wool that a kitten has gotten hold of, and worked it into one big knotted mess. Actually the circulatory system is probably a lot easier to sort out then that wool would be.
Our general knowledge of the heart is, we know if its 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 about these except, that if we cut an artery we could easily bleed to death. Another fact that is fairly common to us, is we know that if we have too much fat in our blood, then cholesterol has something to do with it, and its not good for us. That pretty well sums up our knowledge of the circulatory system. Really when you stop to think about it, that's a fair amount of knowledge.
If we had just a few more details to our knowledge it may drive many us to think about how it really affects our entire bodies, and that by knowing what it needs, and why it needs certain things, we will be all the more likely to ensure it gets it.
Sometimes to thoroughly understand 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 manufacturing plant (the heart). In this plant are four rooms (four chambers of the heart) that each produce 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 various 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 process takes place over and over again continuously. This scenerio is only presented this way as a visualization, to simply help you know how the circulatory system works.
If we wanted to, we could continue 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 exactly would happen in our bodies.
