Definition
defined by structured tissue that secrete them.
Secreted by ductless glands,
Hormones act locally (act on cells adjacent to where the hormone is synthesized or secreted) or are carried by the vascular system to other tissues of the body.
Ovary: responds to hormone but its not considered a gland. |
