Is there a simpler, more poetic term for "the detritus of animal life"?

The words tissue or flesh seem to me nearly general enough for much of "the bits and pieces that make up a person or animal", but flesh typically does not connote fur, hair, feathers, bone; and in dictionary definitions, tissue seems overly specific:

Biology - an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism.

Some other terms to consider:

• dander - "Hair follicles and dead skin shed from mammals."
• stuff of life - flesh and other bits of life - (note, not staff of life, which is bread)
• corpus - "the body of a person or animal, especially when dead" (while corpse specifically refers to a dead body, a corpus may be alive)
• mortal coil - "The physical body of man (containing the spirit inside) ... "what Fletcher calls the ‘case of flesh’""

A minor problem with that last is that nearly any use of it must be overshadowed by Shakespeare's

For in that sleep of death, what dreams may come,
When we have shuffled off this mortal coil,
Must give us pause.

Constituents might fit the bill.
