Body Systems and Homeostasis Test Review

Chewing food is an example of ________________________ digestion.

Place the words below in order from the smallest to largest level of organization:

• Organs, tissues, cells, organ systems

• Cells, tissues, organs, organ systems

• Organ systems, organs, tissues, cells

• Cells, tissues, organ systems, organs

The main purpose of homeostasis is to...

• Fight disease-causing organisms

• Keep internal conditions stable

• Produce offspring

• Replicate DNA

As blood passes by cells of the body, it

• releases oxygen.

• releases carbon dioxide.

• absorbs energy.

• absorbs nutrients

How is breathing related to cellular respiration?

• Breathing supplies the oxygen needed for cellular respiration.

• Breathing supplies the glucose “burned” during cellular respiration.

• Breathing supplies the carbon dioxide needed for cellular respiration.

How do the digestive and circulatory systems interact?

• The circulatory system transports waste and the digestive system rids the waste from the body.

• The circulatory system creates waste and the digestive system rids the waste from the body.

• The digestive system breaks down food and the circulatory system transports the nutrients.

• The digestive system transports nutrients and the circulatory system breaks the nutrients down.

Which body system helps the body to move?

• cardiovascular

• muscular

• excretory

• digestive

Mechanical digestion is

• physically breaking down food into smaller pieces

• chemically breaking down food into its minerals

• eliminating waste

Arteries carry blood

• AWAY

• TO

• They don't carry the blood, they exchange materials between blood and body cells

What is homeostasis?

• the process by which an organism's internal environment is kept stable in spite of changes to the external environment (balance)

• an impulse

• a response to a stimulus

• when oxygen is moved from outside environment into the body
