Body Systems and Bioengineering Solutions

Which best describes a function of the circulatory system?

• transport blood
• provide oxygen
• help move the body
• protect organs

What is the main function of the skeletal system?

• clean the body
• support the body
• deliver nutrients to the body
• carry oxygen throughout the body

Why is the digestive system so important for the human body?

• It circulates blood to all of the organs.
• It moves oxygen through the lungs and into the blood.
• It carries away waste products from the place they are created.
• It breaks food into nutrients and moves the nutrients into the blood.

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 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

What do the muscular system and skeletal system have in common?

• Both systems protect the brain.
• Both systems pump blood to the body.
• Both systems are made up of soft material.
• Both systems assist the body with movement.

Which body system sends messages to the brain?

• nervous
• muscular
• circulatory
• digestive

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.
