Human Body Car Engine

On the record, do not be alarmed with the title. Why I named this article as such is simply because my analogy with the digestive system and nutrition can be correlated with the car engine. What am I talking about? But better ask, however, “What is the common denominator between the human body and car engine?” In this case, we are starting to build a connection. For the purpose of this article, the common characteristic between a car engine and the human body is its reception to oil, in the general sense of the word.

The human body needs essential oils. Good cholesterol would not be called good if not for its vital benefits in the human body. Fats, or the solidified progression of oil in the digestive tract, have a number of uses. Fats primarily insulate the body, therefore offering a natural resistance to higher level of cold or hot conditions. It is of no wonder that in general cases, people within the category of “skinny” have the least endurance being exposed to these conditions. Put two individuals in a steam bath chamber, a skinny man and a corpulent man. Normally, the lanky person would be the first to exit the chamber than the fat one. The other good use of fat is that it gives the body reserved energy in case proteins and carbohydrates depleted. Again, when we compare a thin slip of a man to a barrel-chested gargantuan heavyweight, there’s a vast perspective between these two individuals if put into the treadmill. The bigger man calls it exercise while the skinny man calls it punishment.

Now let us look at the car engine. Of course, it needs oil for the car to ever function. But the kind of oil used in fueling automobiles is not the oil that was directly pumped out of the rigs. Rather, these are distilled and refined products which what we now call as petroleum, or in layman’s term, gasoline. The main reason why crude oil is purified is simple because crude oil contains harmful chemical elements that will endanger the engine at the progression of burning the fuel. Crude oil may often contain sulfur. We all know that in general sense, sulfur may be synonymous to gunpowder. To put something like this in a burning car engine is tantamount to suicide wherein a drunk driver will actually die before he is about to die in a car crash. » Read more: Human Body Car Engine

Important Systems of the Human Body

We talk about the study of life when we talk about biology. This study includes everything about living things – animals, plants or humans. Human biology specifically deals only with the human life form. It deals with all the aspects of the human body. It talks about what comprises the human body and what makes it work.

Our bodies are made up of several systems working interactively. These systems keep the body functioning well so that we may go about our normal lives every single day. We have the nervous, respiratory, digestive, cardiovascular, immune, circulatory, reproductive, excretory, and endocrine system. Each system has its own specialized assignment to do inside us that contribute to our overall well-being.

If one system goes wrong the whole human body is affected. It is therefore important to keep our bodies healthy all the time, so that our systems will be working efficiently for us all the time. This can be done if we have the right knowledge about the human systems. This is the main reason why we have to study biology in our science courses. Let us discuss some of the important human systems.

The Respiratory System is responsible for our breathing. It has two zones namely the upper respiratory tract and the lower respiratory tract. These zones help us inhale and exhale freely. The organs involved in our respiratory systems are the nostrils, nasal cavity, pharynx, larynx, trachea, thoracic cavity, bronchi, and alveoli. The air flows through these organs in a certain proper order. » Read more: Important Systems of the Human Body
