NC Science Coach Chapter 4 Review: Body Systems

Which systems work together to bring oxygen into the body and deliver it to the cells?

• muscular and skeletal systems

• nervous and digestive systems

• respiratory and circulatory systems

• nervous and respiratory systems

Look at the diagram of the nervous system. Which statement is true?

• Nerves carry messages from the hands to the spinal cord and brain.

• Messages from the brain travel first through nerves, then to the spinal cord.

• If one nerve is damaged, messages from other nerves will not be sent to the brain.

• The spinal cord reaches from the brain to the feet.

The respiratory system and the circulatory system work together to move oxygen through the body by:

• The respiratory system brings in oxygen and the circulatory system transports it to cells.

• The circulatory system brings in oxygen and the respiratory system transports it to cells.

• Both systems bring in oxygen and transport it to cells independently.

• Neither system is involved in moving oxygen through the body.

What is the main function of the respiratory system in the human body?

• To break down food for energy

• To transport nutrients to cells

• To exchange oxygen and carbon dioxide

• To send messages to the brain

Which statement best describes how the circulatory and digestive systems interact?

• The digestive system exchanges gases with the environment.

• The digestive system pumps blood throughout the body.

• The circulatory system delivers nutrients absorbed by the digestive system to body cells.

• The circulatory system breaks down food into nutrients.

Which body system is responsible for carrying electrical signals between the brain and other parts of the body?

• Circulatory system

• Digestive system

• Nervous system

• Respiratory system
