What is the endocrine system?

It uses chemical signals to relay regulatory information throughout the body

What are hormones?

They are chemicals secreted by a group of specialized organs called endocrine glands. They are secreted into the blood

Hormone receptor

Can respond to a particular hormone

The major human endocrine glands

1. Thyroid gland

2. Hypothalamus

3. Pituitary gland

4. Pancreas

5. Adrenal gland

6. Gonads

7. Pineal gland

Adrenal glands

They sit on top of the kidney and are composed of the adrenal cortex and the adrenal medulla

Adrenal cortex

Releases a class of steroid hormones called corticosteroids

Adrenal medulla

Releases epinephrine and norepinephrine

Epinephrine

Fight or flight response, stress, pupils dilate, blood vessels contract, heart beats fast, muscles contract

Caffeine

A stimulant, like epinephrine

Alcohol

Depressant, slows brain activity, releases norepinephrine, slow heart rate

Daphnia description

1. Small freshwater crustaceans

2. Outer carapace is transparent

3. 3-5 centimeter

Linear relationship

X and y (alcohol or caffeine concentration and HR)

Y = 0.5842x + 1.6842 (m is slope and b is y-intercept)

Coefficient of determination or R2

Expresses the strength of the relationship between the x and y variables

0.9488
