• Regulate blood pressure

• Promote milk production in females

• Stimulate adrenal gland hormone production

Into which of the following do endocrine glands secrete hormones?

• Saliva

• Bloodstream

• Lymphatic system

• Sweat glands

Steroid hormones are lipid-soluble because they are:

• Water-soluble

• Produced from proteins

• Produced from cholesterol

• Produced from carbohydrates

Endocrine glands are characterized by:

• Having ducts that secrete enzymes to the outside body

• Being a ductless system that secretes hormones directly into body fluids

What is a second messenger?

• A chemical that induces changes after a hormone binds

• The hormone that leaves the gland

Which structure connects the anterior and posterior lobes of the pituitary gland?

• • Pituitary stalk

• • Hypothalamic bridge

• • Sphenoid sinus

• • Optic chiasm

The solubility of steroid hormones allows them to:

• Remain in the digestive tract
