What is a Coelom and who has one? GUEST BLOG

Todays guest blogger is Taylor.

A Coelom is a body cavity that encloses organs in the visceral layer, allowing organs to develope.The Coelom forms when the lateral plate mesoderm splits and it seperates the body into an inner tube and outer tube. Animals that have Coeloms include earthworms and other annelids. Arthropods and mollusks also have a coelom, however theirs is more simplisitic and reduced.

  1. To answer my question, through research I have discovered that animals actually can get Trichinosis. However, most have been able to adapt and grow immunity through exposure when they eat meat that contains these infectious pathogens. The animals develop antibodies that make them capable of eating raw meats without getting sick. Also, the sooner raw meat is eaten after an animal is killed the less likely the consumer will get Trichinosis, and quite a few animals eat their prey immediately after the kill. Lastly, people can eat raw meat, too. However, we completely cook and freeze every bit of pathogen out of our meat, so we make ourselves incapable of eating raw meat without getting sick by not allowing our bodies to slowly be exposed to the pathogens in order to grow immunity (it’s the same concept as a flu shot creates immunity within the body). Some cultures, like the Japanese, particularly have developed immunity to the harmful pathogens in raw meat. In conclusion it is possible
