The first 4 structures in the diagram (in order) are?

• the pituitary gland, the pineal gland, the thyroid, and the thymus
• the hypothalamus, the pituitary gland, the pineal gland, and the thyroid gland
• the pineal gland, the parathyroid glands, the hypothalamus, and the pancreas
• the pineal gland, the pituitary gland, the hypothalamus, and the thyroid gland

When levels go above or below a set point a hormone is released to return the body to set point. When the body is restored to set point no more hormone is released. This is an example of...

• a positive feedback loop
• a negative feedback loop
• a neutral feedback loop

The purpose of the endocrine system is to

• maintain homeostasis by reacting quickly to stimuli
• produce substances that protect the body from bacteria 
• maintain metabolism, growth and development in homeostasis 
• transport molecules throughout the body

Endocrine glands produce __________ which maintain the body in homeostasis

• oils
• neurotransmitters 
• tears
• hormones
