This tissue type covers and protects surfaces, both outside and inside the body.

NERVOUS

CONNECTIVE

EPITHELIAL

MUSCULAR

This is a liquid connective tissue

(a)

What is the function of epithelial cells?

Act as barriers between the external environment, or between organs and fluidfilled cavities

Provide movement by pulling on bones

Provide secretions which help to digest food

Act as the messaging pathway between different areas of the body

What type of tissue SIGNALS the intestines to move food along?

Nervous Tissue

Blood Tissue

Smooth muscle tissue

Skeletal Muscle Tissue

Epithelial

Connective

Muscle

Nervous

11.

Which of the following tissues is made up of cells that conduct impulses?

Epithelial

Connective

Muscle

Nervous

12.

This picture represents which of the levels of organization?

tissue

organism

organ

organ system

13.

Which tissue is responsible for movement?

connective

epithelial

muscle

14.

Positive Feedback loop

decreases the stimulus

increases the stimulus

15.

If the environment gets cold, we will often shiver in order to:

keep body temperature the same as the external temperature

decrease body temperature

increase body temperature

regulate blood pressure

16.

Negative Feedback loop

decreases the stimulus

increases the stimulus

17.

The "cause" for something to happen is the

response

effect

stimulus

homeostasis

18.

A response is

your body's reaction to change

The change in the environment

what happens

19.

According to the model, what is the response to HIGH blood glucose (sugar)?

Pancreas releases insulin into blood

Pancreas releases glucagon into blood

20.

What is the stimulus in the blood clotting model?

Clotting occurs from platelets

Break or tear in blood vessel wall

Clotting proceeds until break is sealed by clot

Released chemicals attract more platelets.

21.

What is the response in the blood clotting model?

Clotting occurs from platelets

Break or tear in blood vessel wall

Clotting proceeds until break is sealed by clot

Released chemicals attract more platelets.

22.

What type of feedback is shown in the blood clotting model?

Positive

Negative

23.

Homeostasis

allows for a wildly fluctuating internal environment

is impossible in vertebrates

is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation
