Dr. V mentioned in class that glands secrete hormones, but they can also
secrete other things. Which example did she provide for this? Correct
Answer-Testes secrete not only hormones, but they also make sperm.
Therefore, they have two functions. Not sure if this is relevant, but
thought I would include it.
