Question

Where is 'keel' present in our body

Answer 1

A keel or carina (plural carinae) in bird anatomy is an extension of the sternum(breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight. Keels do not exist on all birds; in particular, some flightless birds lack a keel structure.
