Diagnostic Paragraph
Considering the things we have discussed in class this week and last week, I would like for you to write a paragraph. This is a diagnostic paragraph which means it will show me your writing skills. This will not be graded for grammatical errors.
Save as a word document and then upload to this assignment.
Write a single paragraph addressing the following question. You do not need to rewrite the question, but you can give your response in paragraph format.
What does it mean to be “college ready”? Do you think you’re ready for college? If so, how? If not, what might you be able to do now that you’re here?
2 peer responses
The discussion rubric is the same as the previous discussion so please answer the question first and then respond to two of your fellow classmates with a substantive response.

Decomp bodies are most definitely a difficult case to tackle, especially given the amount of time passed since death. For those who have been dead for a while, decomposition is so detrimental the majority of the time there is nothing an embalmer can do. There are a significant amount of changes undergoing in the body, all being irreversible, the only thing embalming is able to do is hopefully slow the effects. (autolysis) The enzymes digest the cells which then break down the tissues (lipids and proteins) and microbes in the air affect the tissues as well (putrefaction) therefore a strong solution with high index chemicals, some embalmers choose to use water-less solutions and a lot of it are needed. Gases also accumulate; carbon dioxide, methane, hydrogen sulphide, cadaverine, and putrescine therefore relieving this helps prevent bloating and “popping”. In addition to formaldehyde, aldehydes such as acetaldehyde, methylgloxal, and benzaldehyde can help with preservation. Anticoagulants such as boric acid, borax, sodium salts, magnesium sulfate, sodium chloride, sodium sulfate, and sodium phosphate can help with blood that is clotted. Dyes can help to restore a more natural color. Masking agents can help with the smell. Pre-embalming solutions can help with preparing the body for the rest of the solutions. The use of paraformaldehyde sprinkled and wrapped in cellophane wrap on unexposed areas of the body can help with odor and tissue firming. Cavity embalming through injection and cavity packs can help with preserving the face and hands.
Li’s post:
Once death occurs, the body temperature will begin to cool to match the surrounding temperature. Without blood and oxygen flow, muscle tissue will become stiff and blood will collect to the lower limbs. Then, as the bacteria in the intestine engulf the intestinal wall, the cells lose structural integrity, cell enzymes are released and begin to decompose the cell itself and surrounding tissues. Microorganisms also began to decompose carbohydrates, proteins and lipids. Most of these failures occur in the body, which is invisible from the outside. So why does the stoppage of respiration and blood flow start the process of decomposition? The answer is all chemistry. In the prep room, embalmer uses 4-chloro-3-methylphenol and various salts for fixation, boric acid for disinfection, ethylene glycol for preservation of tissue plasticity, and injection of antiseptic solution containing formaldehyde can slow down the chemical decomposition of human cadavers.
