___BLANK___ system contains glands that secrete hormones into the bloodstream, whereas the ___BLANCK__system secretes substances through ducts.
Answer:
The ENDOCRINE system contains glands that secrete hormones into the bloodstream, whereas the EXOCRINE system secretes substances through ducts.
Explanation:
Those tissues that produce hormones might be classified as:
endocrine glands (produce hormones exclusively),
exocrine glands (produce hormones and other secretions),
non-glandular tissues that secrete hormones but are not glands.
Endocrine organs, also known as ductless glands or endocrine glands, release their secretion directly to the bloodstream. Blood transport hormones to target cells, tissues, and organs, where they stimulate a change in metabolic activities
Exocrine glandsrelease their secretions to a duct of different tissues where they act, such asthe internal or external surface of cutaneous tissues, stomach mucose, or pancreatic ducts.
