Class 9 Question. Answer to Question. Anchal Singh Nov 08, Body Cavity :A body cavity is any fluid-filled space in a multicellular organism other than those of vessels such as blood vessels and lymph vessels. The term usually refers to the space located between an animal's outer covering epidermis , and the outer lining of the gut cavity where internal organs develop.
Animals with a pseudocoelom are known as pseudocoelomates and the group of animals is referred to as pseudocoelomata. Pseudocoelomata are also referred to as blastocoelomata or haemocoelomata. In this case, the body cavity between the gut and body wall is bounded by peritoneum.
Peritoneum is derived from the embryonic mesoderm. This type of cavity or coelom is known as eucoelom or true coelom. The coelomic fluid of true coelom contains amoebocytes. The animals with true coelom are known as coelomates and the group of animals is referred to as coelomata. Coelom is a fluid filled true body cavity, present between the body wall and the digestive tract.
Pseudocoel is a fluid-filled body cavity, present between the mesoderm and the endoderm. Animals with a pseudocoel are known as pseudocoelomates and the group of animals is referred to as pseudocoelomata. The coelom is developed by splitting of the mesoderm. Coelom is present either in vertebrates or invertebrates. Pseudocoelom is present only in invertebrates. Coelom makes the partition to separate biological systems that perform various major functions.
Acoelomates transport nutrients around the body through diffusion due to relatively small with less intricate body plan. In this case, diffusion is enough to perform transport function. The coelomates have complex body plan that need special transport system circulatory system to ship the nutrients around the body.
In this case, coelom is useful to separate circulatory system from abdominal organs. Coelom is a secondary body cavity which is formed during embryonic development by splitting of mesoderm into two layers, a somatic layer and a splanchnic layer.
The perivisceral cavity or splanchnocoel is formed from the greater part of the coelom. Coelom is filled with colorless coelomic fluid which provides space to house the viscera.
