Here's a breakdown:
* True: Many organs do contain specialized cells that secrete fluids. For example:
* Endocrine glands (like the pancreas, thyroid, and pituitary) secrete hormones directly into the bloodstream.
* Exocrine glands (like sweat glands, salivary glands, and the liver) secrete fluids into ducts that lead to other areas of the body.
* False: Not all organs secrete fluids.
* Organs like the heart, lungs, brain, and muscles have different functions than secretion.
* Organs can also be composed of multiple tissue types, not just those dedicated to secretion.
Therefore, a more accurate definition of an organ is:
A group of different tissues that work together to perform a specific function in the body.
Secretion is just one possible function of an organ.
