Shock can be of four different types such as hypovlemic shock (low volume) due to decrease blood volume, cardiogenic shock due to poor heart function, vascular shock due to inappropriate vasodilation, and obstructive shock due tot eh obstruction of blood flow. A common cause of hypovolemic stock is acute (sudden) or hemorrhage. The blood loss may be external, as occurs in trauma , or internal, as in rupture of an aortic aneurysm. Loss of body fluids trough excessive sweating, diarrhea, or also vomiting also can cause hypovolemic shock. Other conditions รข€“ for instance, diabetes , mellitus- may cause excessive fluid of urine. Sometimes, hypovolemic shock is due to inadequate intake of fluid falls, venous return to the heart decline, filling of the hear lessens, stroke volume decreases, and cardiac output decreases. In cardiogenic shock, the heart fails to pump adequately, most often because of a myocardial infarction (heart attack). Other causes of cardiogenic shock include poor perfusion of the heart (ischemia), heart valve problems, excessive preload or afterload, impaired contractility of heart muscle fibers, and arrhythmias. Even with normal blood volume and cardiac output, shokc may occur if blood pressure drops due to a decrease in systemic vascular resistance. A variety of conditions can cause inappropriate dilation of arterioles or venules. In anaphylactic shock, a severe allergic reaction for example, to a bee sting- releases histamine and other mediators that cause vasodilation. In neurogenic shock, vasodilation may occur following trauma to the head that causes malfunction of the cardiovascular center in the medulla. Shock stemming from certain bacterial toxins that produce vasodilation is termed 100,00 deaths per year and is the most common cause of death in hospital critical care units. Obstructive shock occurs when blood flow through a portion of the circulation is blocked. The most common cause is pulmonary embolism, a blood clot lodged in a blood vessel of the lungs.

Sorry, I prefer to have credit for the things that I write. I would never condone someone taking something I've come up with and claiming that it is their own. Plagiarism isn't ONLY copying something word for word. Plagiarism also entails putting information you wouldn't obviously know yourself into your own words from another source without the original idea being yours. Even paraphrasing someone else, you need to give credit to them. It is best you do this yourself. The material you've posted is in very easy language to understand. Teachers, college professors especially, employ databases on the Internet to search for the originality of their students' papers. If something does not sound like the student and they preform a search, it may very well bring this yahoo question to their attention. That is an automatic F in the class and perhaps expulsion from school. I suggest learning something and doing the work for yourself.

Way to long, I have my own assignments to do. High light the important parts and use them, if its for a assignment just change all the words around and use a thesaurus ( there is one on the computer if you want to google it) all you have to do is look up the word and it will give you 5 other ways you can write it. Somestimes you can change it so the last bit of the sentance is at the beginning and the beginning is at the end. There is words you will be able to change into your own, Write it in away you understand. I know its hard, but you learn heaps faster doing it yourself. Make sure you reference it to show where you getting the information from and use quotes "" in areas you have copied (you shouldnt use to many quotes though). Anyway good luck with that one
