Definition of perigynium. 1 : a fleshy cup or tube that surrounds the archegonium of various bryophytes (as of the liverwort group) and that is formed either from the stem apex or from the thallus.


The peritoneum is the serous membrane which forms the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue.
