The Human Body Maintenance System

The human body consists of organs and organ systems which work together to maintain both internal and external conditions of the body. The importance of the human body's maintenance system is indeed very high. Individuals can easily get sick due to the imbalances of the internal conditions and different fluctuations that can occur anytime due to any cause. External conditions can greatly affect the internal conditions of the human body especially when the immune system or other systems work inefficiently within the human body. There are several factors causing these changes and fluctuations. However, the human body tries its best to maintain the right condition or the dynamic equilibrium (which is around 37 degrees Celsius).

The basic maintenance system works with blood vessels, tissues, and tissue fluids as they are important factors to regulate changes in the body condition. By adding or removing the substances from blood vessels, tissues, and tissue fluids, the five main body systems work effectively to reach dynamic equilibrium.

Are Humans and Chimpanzees Really the Same Species Just Different Breeds?

Humans are a magnificent species, quite incredible as far as that goes, of course evolution has certainly had a lot of time to perfect an upright walking carbon bi-ped based design hasn't it. What about the other similar strategies, designs, or species? Well, there certainly isn't much difference between chimpanzees and humans, in fact, I often "people watch" and realize that human behavior is nearly identical at times - look at the US Congress for instance, no I am not digressing. Okay so, let's talk shall we?

Humans like to think (read: assume) that they are somehow more special than all the other animals in the animal kingdom - truth be told - humans are from that same kingdom - and although bigger brains and perhaps a better combination of organic sensors allowing them to be top of the mammalian food chain, the reality is, there isn't much difference really - some 1.5% in DNA from chimps and humans, and about half of that is due to humans inferior, yes inferior, since of smell.

How Did Pharmaceutical Quality Control Develop?

The process of creating medication has a long, rich history, dating back far beyond what we now consider to be the modern pharmaceutical industry. In the beginning, medications were compounded by tribal elders or village medicine making artisans, consisting of local herbs and other ingredients. While there was no official pharmaceutical quality control or pharmaceutical quality assurance at this time, the fact that only well-trained artisans were counted on for medicine speaks to the importance of quality in the process, even then. Since those times, dating back many thousands of years BC, medicine has become an industry, and today there are strict regulations in all areas of production and delivery. Below is a brief history of how quality control came to be in the pharmaceutical industry.

The "Wild West" Days of Pharmaceuticals

• From the late 18th century to the early years of the 20th century, medication was rarely if ever regulated, harkening back to the days of the Wild West, or any other great frontier. The problem at the time was two-fold; first, dangerous, addictive medications which are banned today could be purchased, often without a prescription, at many drug stores; second, that any person could market any concoction as a miracle cure, without any evidence to back up their claim. These problems, along with some others, led to a natural progression through which quality control became a concern. Still, it would take time, and great advances in the industry, to spur on true change.
