Question 1

Endocrine System

Answer 1

chemical system of communication in the body via the blood stream.
secrete hormones
pituitary gland and the adrenal glands
Target cells
receptors
physiological reaction

Question 2

The Pituitary Gland

Answer 2

The pituitary gland is located in the brain and is controlled by the hypothalamus. The pituitary gland controls the release of hormones from all other glands. For example, it produces adrenocorticotrophic hormone (ACTH) which is involved in the stress response by stimulating the production and release of cortisol from the adrenal glands.

Question 3

The anterior pituitary gland

Answer 3

The anterior pituitary gland releases the hormone called ACTH which regulates levels of cortisol.

Question 4

The posterior pituitary gland

Answer 4

The posterior pituitary gland is responsible for releasing oxytocin which is crucial for infant/mother bonding

Question 5

Adrenal Glands

Answer 5

We have two adrenal glands situated on top of each kidney. Each adrenal gland is made up of two distinct parts. The adrenal gland produces adrenaline which triggers the fight or flight response and increases heart rate, breathing rate, contracts blood vessels etc.

Question 6

Adrenal Cortex

Answer 6

The outer section of the adrenal gland is called the adrenal cortex. It produces the hormone cortisol which is produced in high amounts when someone is experiencing chronic stress. Cortisol is also responsible for the cardiovascular system, for instance it will increase blood pressure and causes blood vessels to constrict.

Question 7

Adrenal Medulla

Answer 7

The inner section of the adrenal gland is called the adrenal medulla which produces adrenaline, the hormone that is needed for the fight or flight response that is activated when someone is acutely stressed. Adrenaline increases heart rate, dilates pupils and stops digestion.
