to determine the mole of the atom
glands secrete chemical messengers called leucocytes?
Hormones
it is use for chemical digestion as it emulsifies fats.
Yes. They are called chemical messengers.
"hormones"
Neurotransmitter.
Hormones
Paracrines
Cyclic AMP and calcium may be second messengers
I believe they are called chemical messengers because of their function and the fact it is a chemical. They travel through the blood and target cells respond to hormones often because of their structure. I have read in a science book (McDougal Littell 's Human Biology) that they are called chemical messengers because they are made at one location and function at another.
chemical messengers
They act as an active "bridge".
