There are four basic kinds of tissue in the body:
5. A thin, finely woven fabric with a gauzy texture.
6. Etymology: a "band or belt of rich material", from Old French tissu, "a ribbon, headband, belt of woven material" (from about 1200); noun use of tissu, "woven, interlaced"; past participle of tistre, "to weave"; from Latin textere, "to weave".
The biological sense of "tissue" is first recorded in 1831, from French; introduced about 1800 by French anatomist Marie-François-Xavier Bichal (1771-1802).
Tissue-paper is from 1777, supposedly so called because it was made to be placed between tissues to protect them. The meaning of "piece of absorbent paper used as a handkerchief" came from 1929.
She had a slight cut on the tissue of her upper arm; so, she used a paper tissue to stop the bleeding.
One of the important elements of connective tissues involves cartilage which is a rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ears, the nose, the bronchial tubes, the intervertebral discs, and many other components of the physical system.
2. Tissue from the sinoatrial node or atrioventricular node in the heart.
Adipose tissue is normally called "fat tissue" and consists of large spherical cells filled with fat. Major layers are in the inner layer of the skin and around the kidneys and heart.
