Watch this vid about organs: Biology definition: An organ is a group of tissues that perform a specific function or group of functions. Typically, an organ would have the main tissue component that characterizes the organ and other tissues, such as those associated with the organ’s structure...
Human body tissue makes up organs and other body parts. There are four types of tissue: muscle, epithelial, connective and nervous. All tissues are made up of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes ...
In biology, atissueis a group of cells and their extracellular matrix that share the same embryonic origin and perform a similar function. Multiple tissues then form organs. The study of animal tissues is calledhistology, orhistopathologywhen it is concerned with diseases. The study of plant tiss...
This includes tissues and organs removed during surgical procedures or autopsies.Pathological wastecan contain infectious agents and must be handled with care, often requiring incineration or other high-temperature biomedical waste treatments to ensure complete destruction. ...
Epithelial tissues(orepithelium) are the most abundant human tissues. They cover the whole surface of the body forming theepidermislayer of theskin. Moreover, it covers the lining of body organs forming mucus lining, such as the digestive system lining. Thus, they protect the organ from externa...
Diuretic, any drug that increases the flow of urine. Diuretics promote the removal from the body of excess water, salts, poisons, and accumulated metabolic products, such as urea. They serve to rid the body of excess fluid that accumulates in the tissues
the units of the biosphere are those of the organism:organsystems composed of organs, organs of tissues, tissues of cells, cells of molecules, and molecules of atomic elements and energy. The progression, therefore, proceeding upward from atoms and energy, is toward fewer units, larger and more...
Although some organisms only have one cell or a small number of cells, the large organisms are structured at several levels: cells, tissues, organs, and organ systems. Cells are considered to be the basic units of life, but they also contain their own organization: parts that work together ...
sexually mature, males and females find one another and the female actually lives within a channel on the males back. The female lays thousands of eggs that ultimately leave the body through the host's feces or urine. Some eggs may become trapped in body tissues or organs causing inflammation...
Although it is certainly true that the possession of hard parts enhances the prospect of preservation, organisms having soft tissues and organs are also occasionally preserved. Insects and even small invertebrates have been found preserved in the hardened resins of conifers and certain other trees. ...
