Which is an example of how the muscular system and skeletal system work together?

• Voluntary muscles hold the skeleton in an upright position.

• The skeleton helps protect muscles from damage.

• Smooth muscles help protect the bones and ligaments.

• The skeleton helps keep cardiac muscles pumping blood.

Which two body systems work together to provide the body with new red blood cells that carry oxygen?

• skeletal and digestive

• muscular and digestive

• Skeletal and Respiratory

• muscular and respiratory

Which best describes the circulatory system?

• It protects the major organs of the body

• It breaks food into nutrients for the body.

• It sends messages to the brain to protect the body.

• It transports oxygen-rich blood throughout the body.

Which task in the human body is accomplished through the combined efforts of the cardiovascular and muscular systems?

• protecting major body organs

• pumping blood throughout the body

• releasing waste products from the body

• moving water and nutrients from one organ to another

Which example best shows structures that make up the digestive system in the human body?

• heart, blood, vessels

• nose, trachea, lungs

• brain, spinal cord, nerves

• esophagus, stomach, intestines

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.

When someone is exercising, which is most likely a function of both the circulatory and respiratory systems?

• to help the body sweat

• to make the muscles work

• to provide oxygen to the body

• to protect bones from breaking

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.

Which body system coordinates and communicates with all other body systems?

• respiratory system

• circulatory system

• digestive system

• nervous system

Which best describes how the digestive system compares to the respiratory system?

• The digestive system provides oxygen for cells, while the respiratory system provides nutrients to cells.

• The digestive system removes waste, while the respiratory system breaks down food.

• The digestive system provides nutrients to cells, while the respiratory system provides oxygen for cells.

• The digestive system moves nutrients through the bloodstream, while the respiratory system removes waste.
