secretions
Glands produce them
Secretions are substances produced and released by cells, glands, or organs in living organisms.
The term covers a wide range of biological outputs, from saliva and sweat to hormones and digestive enzymes.
In medical and scientific contexts, secretions often refers specifically to fluids released by mucous membranes, as in respiratory secretions.
The word can also appear in broader contexts describing any substance that oozes or is discharged from something.
