Any new bumps that appear anywhere on your body should be a cause for alarm for any person, and it is always necessary to visit a physician to have them reviewed. The fact that you are a non-smoker is a good thing, as smoking obviously has been found to cause many cancers, including cancers of the mouth.
A coelom is a cavity that separates the gut from the body wall. Most animals are coelomates, meaning they have a coelom. The coelom allows the body's internal organs to develop independently of the body wall.nimals without it, such as flatworms, are called acoelomates. In between there are some animals called pseudocoelomates, which possess a false coelom, which is an unlined or partially lined body cavity between the gut and body wall. A coelom is defined as a cavity that separates the gut from the body wall.
coelom - (Greek, koilma = cavity) Term used to describe a fluid-filled cavity or space. Placental vertebrate development have both extraembryonic (outside the embryo) and intraembryonic (inside the embryo) coeloms. The extra-embryonic coeloms include the yolk sac, amniotic cavity and the chorionic cavity information on these spaces can also be found on placental development pages.
