Tissue is a cellular organizational level intermediate between cells and a complete organism. Hence, a tissue is an ensemble of cells, not necessarily identical, but from the same origin, that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The study of tissue is known as histology or, in connection with disease, histopathology. The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. In the last couple of decades, developments in electron microscopy, immunofluorescence, and the use of frozen tissue sections have enhanced the detail that can be observed in tissues. With these tools, the classical appearances of tissues can be examined in health and disease, enabling considerable refinement of clinical diagnosis and prognosis. From Wikipedia under the

Answered by Chem Man - Fri May 1 21:49:00 2009 Atheists do you believe in such thing as freewill?
Q. In your point of view, our body are simply just some sort of biological machines. And our minds are just supercomputer made out of soft tissues (which happen to be developed through series of accidental evolutionary process with no purpose or guidance). With this view there is really no room for something like freewill. Do you accept the idea that no one is really morally responsible for their bad behavior? That we are not a conscious and self-aware being; that it is just a complex biochemical illusion? Asked by . - Sat Apr 18 08:31:54 2009 - - 23 Answers - 3 Comments A.
