Understanding the Endocrine System

What is the primary role of the endocrine system in the human body?

• To transport oxygen throughout the body

• To regulate body processes by releasing hormones into the bloodstream

• To provide structural support to the body

• To protect the body from pathogens

How does the endocrine system differ from the nervous system in communication?

• The endocrine system uses electrical impulses for fast communication

• The endocrine system uses hormones for slow, long-lasting communication

• The nervous system uses hormones for slow communication

• The nervous system uses chemical messages for long-lasting effects

• Base of the brain, below the hypothalamus

The primary function of the adrenal glands is to (a)   .

• To produce insulin and glucagon

• To regulate stress responses, metab

• To control growth and development

• To produce thyroid hormones

_____ is the hormone responsible for stimulating growth, cell repair, and metabolism.

What is the primary function of thyroid hormones (T3 and T4)?

• To regulate blood sugar levels

• To manage stress and inflammation

• To regulate metabolism, energy production, and oxygen use in cells

• To stimulate muscle growth

How do insulin and glucagon work together in the body?

• Both lower blood sugar levels

• Insulin raises blood sugar, glucagon lowers it

• Insulin lowers blood sugar, glucagon raises it

• Both raise blood sugar levels

What is the role of insulin during exercise?

• To increase heart rate and blood pressure

• To facilitate glucose uptake into cells for energy

• To promote the breakdown of glycogen

• To reduce inflammation

What effect do chronic high levels of corticosteroids have on the body?

• Enhance muscle growth and recovery

• Suppress the immune system and impair recovery

• Increase energy availability

• Improve cardiovascular health

Where is the thyroid gland located?

• In the abdominal cavity

• Front of the neck, below the Adam’s apple
