To produce and separate out (a substance) from cells or bodily fluids.
To create and release a substance.
Many processes in the plant and animal worlds rely on specialised cells secreting a specific substance. The verb 'to secrete' simply means that a cell makes a substance (mucus, wax, a hormone) and then discharges that substance to the outside of the cell. The goblet cells in our noses secrete mucus when we have a cold, so that the viral particles get trapped in it. The silkworm caterpillar secretes a fine thread from cells in a gland. It winds these around it to form a pupa. The mint plant secretes a pungent oil from special cells in its leaves and stem to deter grazers - and so on
to form and give off, as in the formation and release of sweat in mammals; amphibians have many skin secretions.

To make and give off such as when the beta cells make insulin and then release it into the blood so that the other cells in the body can use it to turn glucose (sugar) into energy.
The process of segregating, elaborating, and releasing some material specialized (like saliva) or isolated for excretion (like urine).
