Human Body Systems and Organization Review

Front

What is the function of the muscular system?

Back

The muscular system allows movement of the body and helps maintain posture. Smooth muscles help move food through the organs they surround.

Front

How does exercise affect the respiratory system?

Back

Exercise increases breathing rate which sends more oxygen to the muscles.

Front

What is the primary function of the digestive system?

Back

The function of the digestive system is to break down food and absorb nutrients for energy and growth.

Front

How does the respiratory system support other body systems?

Back

The respiratory system brings in the oxygen that all the systems need to function.

Front

What are the main body systems involved in movement?

Back

The muscular system and the skeletal system work together to enable movement.

Front

What is the role of the circulatory system?

Back

The circulatory system transports blood, nutrients, oxygen, carbon dioxide, and hormones throughout the body.

Front

What is the function of the nervous system?

Back

The nervous system controls and coordinates body activities by transmitting signals between different parts of the body.

Front

What is the role of the respiratory system?

Back

The respiratory system is responsible for taking in oxygen and expelling carbon dioxide.

Front

What do involuntary muscles do?

Back

Involuntary muscles, such as those in the heart and digestive organs, function without conscious control.

Front

What is the difference between voluntary and involuntary muscles?

Back

Voluntary muscles are controlled consciously (e.g., skeletal muscles), while involuntary muscles operate automatically (e.g., cardiac and smooth muscles).
