There are quite a few versions of the sign for "lungs."
All of them to some extent make an effort to indicate where the
lungs are.
In addition to "indexing" with the "index finger," a "bent hand" is a
fairly well established handshape used to "point" to certain body
parts, internal organs, and muscles. In this version of the sign for
"lungs" I'm using bent hands. The movement starts at the top and
moves down twice. (Getting the movement right is important so as to
distinguish this sign from other similar but different signs such as
"young" and/or "tired.")
LUNGS (formal version)






LUNGS (flattened-CLAW version)
I listed "bent-hand" version (above) first in this list because it
is very specific and doesn't have overlapping meanings such as
"asthma" or "pneumonia." There is however an even more common
sign for "lungs" than the bent-hand version and that is a version
which uses loose-5 and/or "flattened-claw" hands.






LUNGS (Classifier-"C" version [CL:C])
The "Classifier C" version of lungs is helpful when you need to
specify the lungs and want to indicate the general size, shape, and
placement. The sign holds two palm-back C-hands at the top of your
chest and moves them downward one time (generally) in a deliberate
and relatively quick motion with a very brief hold at the end.
