The Endocrine System Chapter 13.9

Introduction to the Glandular Systems The glands of the body make substances that help regulate the body process Glands are divided into two categories, exocrine and endocrine Exocrine glands have ducts that carry substances to organs, body parts, or outside the body The substance made by the gland is excreted and is deposited in the organ or body part.

Introduction to the Glandular Systems Examples: Digestive juices from the salivary glands, pancreas, and gallbladder Milk from female mammary glands Moisture from sweat glands Sebum (oil) from the sebaceous glands Tears from the lacrimal glands

Introduction to the Glandular Systems Endocrine glands are glands without ducts They secrete hormones directly into the bloodstream The secretions from these glands are separated into two main groups: External secretions: fluids that are carried to a nearby organ or to outside the body Internal secretions: hormones that are carried to all parts of the body through blood or lymph systems.
