DESCRIPTION
The Endocrine S ystem Endocrine glands produce hormones Hormones are secreted directly into the blood Blood transports them all over the body. Target cells have specific receptors in their membranes which the molecules bind to Groups of target cells are called target tissue. - PowerPoint PPT PresentationTRANSCRIPT
The Endocrine System
•Endocrine glands produce hormones•Hormones are secreted directly into the blood•Blood transports them all over the body
•Target cells have specific receptors in their membranes which the molecules bind to
•Groups of target cells are called target tissue
