Question 15

What is the difference between the Endocrine glands and Exocrine glands?

Answer 15

Endocrine glands- Secrete hormones carried by blood.

Exocrine glands- Produce decorations released via ducts. E.g. Sweat gland, gastric gland.

Question 16

What is the function of hormones?

Answer 16

They regulate activity of their target organ.

Response produced by hormones is slower but lasts longer and complements rapid and relatively short-lived responses produced by nervous system.

What is the function of the endocrine system?

Answer 19

1- Part of the regulatory system of body

2- Works with nervous system

3- Endocrine glands secrete hormones carried by blood to target organs.
