What is mean by homeostasis?

Controls and coordinates body activities through chemical

controls and coordinates body activities through electrical impulses

For maintenance of a steady state in the internal environment

remove metabolic waste products from the cel

which of the organ will balance the glucose level in the body?

Stomach

Small intensine

Deodenum

Pancrease

What is involuntary contractions of voluntary muscles to warm up?

Shivering

Sweating

Vasodilation

Vasoconstriction

Which is NOT a characteristic/example of positive feedback?

Enhances the stimuli

Body temperature, Blood pressure

Labor contractions

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

When you are cold, you shiver and your blood vessels contract, which warms you up. When you are hot, you sweat and your blood vessels expand, which cools you down.

Positive Feedback Response

Negative Feedback Loop

What is another word that can be used to describe "homeostasis"?

STABLE

EQUAL

COMPLETE

CORRECT

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels.

Positive Feedback Response

Negative Feedback Loop

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

10.

What hormone is produced in the pancreas that lowers blood sugar?

Insulin

Glucagon

Ketones

Glucose

11.

Sweating cools the body through a process called

conduction

evaporation

ionisation

dehydration

12.

Blood sugars are controlled by

brain generated chemicals

blood

hormones from the pancreas

chemicals from the liver

13.

The hormone that makes the liver store sugars is

glucose

glycogen

glucagon

insulin

14.

The liver normally stores blood sugar as

glucose

glycogen

glucagon

fats

15.

The action of insulin causes

The liver to secrete enzymes

The liver to make glycogen

The liver to make glucose

none of these

16.

High blood sugar levels after a meal usually stimulate

Glucagon release from the liver

Glucagon release from the pancreas

Insulin release from the liver

Insulin release from the pancreas

17.

After a period of strenuous exercise you may need to

drink tea

drink water with electrolytes

drink a high energy drink

drink water

18.

What is a receptor?

Receptors are located in the skin

Receptors carry messages to the hypothalamus

A receptor receives messages and causes a response

Receptors or sensors detect changes in the body

19.

What is not a respond by the human body when the temperature of body increases?

Sweat gland secrete more sweat

Produce hormone to increase the metabolic rate

Blood vessels dilate

Hair erector muscles relax

20.

If a person cant control the glucose level in the body can lead to what sick?

Heart attack

High blood pressure

strok

Diabetes
