Thick Endometrium

Endometrium is the inner lining of the womb.The womb proper is a solid, muscular organ, the thickness of its wall is about one -third of an inch, but its inner lining or mucous membrane is only 1/25 of an inch in thickness and consists of a single layer of columnar cells which have a hairlike growth (celea) on their surfaces making it seem velvety.

This layer of cells dips down forming shallow straight glands, like pores in the skin.The glands secrete a thin, clear mucus when in healthy state.But when infection is introduced, as in an acute and chronic endometritis, the discharge becomes dirty, offensive and irritating, just as in the case of a bad infection in the nose when the discharge changes from clean, watery mucus to pus-like phlegm
