Glucose(or other metabolic fuel)
ATP(cellular energy)

Question 17

What systems deliver oxygen, glucose, and ATP to the cells of the body?

Answer 17

The digestive, respiratory, and cardiovascular systems

Question 18

Muscle and nerve cells require a steady supply of…?

Answer 18

glucose and oxygen

Question 19

Integumentary System

Answer 19

forms the external body covering and protects deeper tissues from injury; skin, nails, and hair

Question 20

Skeletal System

Answer 20

protects and supports body organs, and provides a framework the muscles use to cause movement. Blood cells are formed within bones. Bones store minerals and are constantly remodeling themselves.

Question 21

Muscular System

Answer 21

allows manipulation of the environment, locomotion, and facial expression. Maintains posture and produces heat.

Question 22

Nervous System

Answer 22

as the fast acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands

Question 23

Endocrine System

Answer 23

glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use(metabolism) by body cells

Question 24

Cardiovascular System

Answer 24

blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood

Question 25

Lymphatic System/Immunity

Answer 25

picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in the lymphatic stream

Question 26

Respiratory System

Answer 26

Keeps blood constantly supplied with oxygen and removes carbon dioxide.

Question 27

Digestive System

Answer 27

Breaks down food into absorbable units that enter the blood for distribution to body cells.

Question 28

Urinary System

Answer 28

Eliminates nitrogenous wastes from the body. Regulates water, electrolyte and acid-base balance of the blood.

Question 29

What do we need for survival?

Answer 29

-Nutrients
-Oxygen
-Water
