Intro Sample...

I know the answers to most of the question that I get asked, but there are a few questions that I get asked that I do not know the answer too. The most common question: What is the gel in to bottom of the tube for? Once my patients ask me that first initial question my head goes to work, I start running question through my head that I do not have the answers to. So the initial question that I will be answering in this paper is how does a serum separator tubes (SST) work?
But before I can answer that question we need to cover the basics about blood in general. First question is what is blood? Blood is a specialized bodily fluid that delivers necessary substances to the body's cells such as nutrients and oxygen and transports waste products away from those same cells. What are the functions of blood? Blood performs many important functions within the body including:
• Supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells)
• Supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (e.g., blood lipids)
• Removal of waste such as carbon dioxide, urea, and lactic acid
• Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies
• Coagulation, which is one part of the body's self-repair mechanism
• Messenger functions, including the transport of hormones and the signaling of tissue damage
• Regulation of body pH (the normal pH of blood is in the range of 7.35 - 7.45Regulation of core body temperature
• Hydraulic functions
So now we know why a doctor would want to have blood drawn and tested. And now we finally get to the good stuff. We will discuss the different parts of the blood, and the ways that it is transported. Blood contains four key elements that include red blood cells, white blood cells, plasma and serum. Red blood cells are the most common type of blood cell a View More »

    Geothermal Energy is the use of the energy in the earth, the natural heat the earth produces. There are several ways to harness this power, and frequently these sources are totally renewable and re-usable. These natural alternatives have been preferred by many over using the fossil fuels so prevalent in society at this time, in that they can be used without the environmental arguments presently going on about fossil fuels. Geothermal energy was first discovered in the seventh century, when mines dug were found to be actually hotter than the surface. This was assumed to be resulting fr

    Tuesday, March 9, 7:30 a.m. -- Denver Nuggets coach George Karl pops in his mouthpiece and puts on his helmet and braces himself for a brutal 15 minutes, but this isn't football. This is cancer radiation. We're at Denver's Swedish Medical Center. The helmet is actually a white, hard-mesh mask that fits to every contour of Karl's big bucket head. It has red crosses all over it, like a hockey goalie's. He lays his 283 pounds on the table and the technicians clamp the mask on hard. How Karl breathes I'll never know. They secure his limbs and ask him to hold a blue plastic donut so no part of h

    The sun inched through the green and ivory curtains and unmasked the layers of dust that floated around the room. It seemed like so many years ago. It was sometime in the summer between the hot months of June and July; the last day of a weeks vacation. I sit, peeling an orange with a knife, so as not to break my just painted red-satin nails, feet propped up on the table, un-shoed and sock-less. I notice the lime-green smoothie mixer that came complimentary with the hotel room. I guess that it had to be from Target and remember that I need to buy a new razor and shampoo and
