ETYM Latin, rib. Related to Coast.
A riblike part of a plant or animal (such as a middle rib of a leaf or a thickened vein of an insect wing).
In biology, the main respiratory organ of most fishes and immature amphibians, and of many aquatic invertebrates. In all types, water passes over the gills, and oxygen diffuses across the gill membranes into the circulatory system, while carbon dioxide passes from the system out into the water.
In aquatic insects, these gases diffuse into and out of air-filled canals called tracheae.
Respiratory organ of aquatic animals that breathe oxygen dissolved in water; SYN. branchia.
ETYM as. rib, ribb; akin to Dutch rib, German rippe, Old High Germ. rippa, rippi, Dan. ribbe, Icel. rif, Russ. rebro.
1. A riblike supporting or strengthening part of an animal or plant.
2. Something resembling the rib of an animal.
3. Cut of meat including one or more ribs.

(Anatomie) Costa, bei Wirbeltieren längl. gebogene Knochen, die in wechselnder Anzahl von der Wirbelsäule ausgehend nach unten bzw. (beim Menschen) nach vorn ziehen u. den Leib beiderseits umfassen. Der Mensch hat 7 sog. echte Rippenpaare, die knorpelig mit dem Brustbein verwachsen sind; weitere 3 Paare hängen durch knorpelige Rippenbögen am Brustbein an, die 11. u. 12. R. enden frei. Alle R. sind gelenkig mit den Wirbelkörpern der Brustwirbelsäule verbunden u. bilden mit dem Brustbein den knöchernen Brustkorb.
Any of 24 curved arches of bone extending from the spine to or toward the sternum in man and a similar bone in most vertebrates; SYN. costa.
Long, usually curved bone that extends laterally from the spine in vertebrates. Most fishes and many reptiles have ribs along most of the spine, but in mammals they are found only in the chest area. In humans, there are 12 pairs of ribs. The ribs protect the lungs and heart, and allow the chest to expand and contract easily.
At the rear, each pair is joined to one of the vertebrae of the spine. The upper seven are joined by cartilage directly to the breast bone (sternum). The next three are joined by cartilage to the end of the rib above. The last two (“floating ribs”) are not attached at the front.
