Coelom. Cross-section of an oligochaete worm. The worm's body cavity surrounds the central typhlosole. The coelom (or celom) [ 1] is the main body cavity in many animals [ 2] and is positioned inside the body to surround and contain the digestive tract and other organs. In some animals, it is lined with mesothelium.
Role in disease. Mesothelioma: ( cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in ...
Eukaryotic motile cilium. A cilium is assembled and built from a basal body on the cell surface. From the basal body, the ciliary rootlet forms ahead of the transition plate and transition zone where the earlier microtubule triplets change to the microtubule doublets of the axoneme.
Gastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract. The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products. The GI tract is composed of the alimentary canal, that runs from the mouth ...
The extracellular fluid compartment is further subdivided into the interstitial fluid and the intravascular fluid compartments. Body fluids, bodily fluids, or biofluids, sometimes body liquids, are liquids within the body of an organism. [ 1] In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is ...
A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity. In the dorsal body cavity the brain and spinal cord are located.
62999. Anatomical terms of microanatomy. [ edit on Wikidata] In vertebrates, an odontoblast is a cell of neural crest origin that is part of the outer surface of the dental pulp, and whose biological function is dentinogenesis, which is the formation of dentin, the substance beneath the tooth enamel on the crown and the cementum on the root.
Interstitium. The interstitium is a contiguous fluid-filled space existing between a structural barrier, such as a cell membrane or the skin, and internal structures, such as organs, including muscles and the circulatory system. [ 1][ 2] The fluid in this space is called interstitial fluid, comprises water and solutes, and drains into the lymph ...
