respiratory
Which best describes how the muscular system impacts movement of the human body?
When a muscle expands, it pulls on the bone it is connected to and the bone moves.
When a muscle contracts, it pulls on the bone it is connected to and the bone moves.
When a muscle contracts, it pushes on the bone it is connected to and the bone moves.
When a muscle expands, it pushes on the bone it is connected to and the bone moves.
What roles do the muscular and respiratory systems serve in the body when someone lifts weights?
The muscular system allows the person to lift the weights, while the respiratory system provides oxygen to the body.
The muscular system provides oxygen to the body, while the respiratory system allows the person to lift the weights.
The muscular system provides nutrients to the blood, while the respiratory system provides sweat to cool the body.
The muscular system provides sweat to cool the body, while the respiratory system provides nutrients to the blood.
Which is an example of a function the muscular system performs?
Voluntary muscles pump blood through the body.
Skeletal muscles keep a body’s joints working properly.
Cardiac muscles move bones and hold a body’s skeleton in place.
Smooth muscles help move food through the organs they surround.
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.
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 cardiovascular system?
It delivers blood to the body’s tissues.
It supplies stability to the skeleton.
It delivers food to power the body.
It supplies oxygen to the body.
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.
