Human Body Systems

Which system of the human body provides protection to most of the major organs?

• skeletal system

• circulatory system

• respiratory system

• muscular system

Which best describes the circulatory system?

• a system made up of the brain and nerves that delivers nutrients and

  removes waste from the body

• a system made up of vessels and blood that delivers nutrients and

  removes waste from the body

• a system made up of the brain and nerves that delivers messages

  throughout the body

• a system made up of the heart and blood that delivers messages

  throughout the body

Which best describes the relationship between the cardiovascular system and the muscular system?

• The cardiovascular system captures carbon dioxide from the air for

  muscle energy.

• The cardiovascular system produces red blood cells to bring oxygen to muscles.

• The cardiovascular system provides a framework for muscle movement.

• The cardiovascular system delivers oxygen for muscle energy.

Which best describes the purpose of the respiratory system?

• to supply oxygen to cells

• to supply protection to organs

• to supply food and nutrients to the body

• to supply blood to the brain and muscles

In which system does the heart work to move blood throughout the body?

• digestive system

• muscular system

• respiratory system

• cardiovascular system

Which best describes the relationship between the skeletal system and the circulatory system?

• The skeletal system transports red blood cells after the circulatory system produces them.

• The skeletal system protects red blood cells and the circulatory system pumps those cells through veins and arteries.

• The skeletal system produces red blood cells and the circulatory system transports those cells where they need to go.

• The skeletal system helps put oxygen in red blood cells and the circulatory system helps those cells rid the body of carbon dioxide.

The circulatory system transports waste through the bloodstream. Which is the best example of another system working to remove waste from the body?

• The respiratory system releases carbon dioxide.

• The skeletal system produces new red blood cells.

• The digestive system breaks down food into nutrients.

• The nervous system send signals from the brain to the muscles.

Which best compares the respiratory system to the circulatory system?

• The respiratory system transports oxygen to cells, while the circulatory system provides oxygen for cells.

• The respiratory system provides oxygen for cells, while the circulatory system transports oxygen to cells.

• The respiratory system breaks down food for cell energy, while the circulatory system rids the body of waste.

• The respiratory system rids the body of waste, while the circulatory system breaks down food for cell energy.

How do the muscular and skeletal systems work together to help the body?

• They provide blood to the body.

• They provide nutrients to the body.

• They provide structure and movement for the body.

• They provide oxygen and carbon dioxide to the body.

How does the circulatory system work with the digestive system?

• Blood is used to build muscle strength.

• Food is broken down in the bloodstream.

• Blood carries nutrients throughout the body.

• Food waste is filtered by the heart and blood vessels.
