Step 1
Other than the secretion of hormones, how does an endocrine gland differ from an exocrine gland?
Answer
An endocrine gland is ductless and secretes hormones directly into the bloodstream, whereas an exocrine gland has ducts and releases its secretions to specific sites, like the surface of the skin or into body cavities.
Step 2
State two ways in which hormone action differs from nerve action.
Answer
- Hormonal action is characterized by chemical transmission, while nerve action involves electrical impulses.
- Hormones generally have a slower action and produce longer-lasting effects compared to nervous impulses, which act quickly and are typically short-lasting.
Step 3
Copy the following table into your answer book and fill each of the empty boxes.
Answer
Endocrine Gland: Islets of Langerhans Location: Pancreas Hormone: Insulin Role of Hormone: Regulates blood sugar.
Endocrine Gland: Thyroid Gland Location: Neck or described Hormone: Thyroxine Role of Hormone: Growth in young or rate of metabolism.
Endocrine Gland: Adrenal Location: On kidney Hormone: Adrenaline Role of Hormone: "Fight or flight" response.
