Skeletal and Muscular Systems

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

• nervous

• muscular

• respiratory

• skeletal

2. What is one of the main functions of the skeletal system?

• aiding in the digestion of food

• getting rid of waste products

• storing fat and protein

• providing structure and support

3. Timothy was playing soccer in a match on Saturday. He ran down the field, kicked the ball, and scored a goal for his team. Many of Timothy's body systems worked together to allow him to score the goal. How did his muscular system help him?

• It broke down food into nutrients the body needs for energy and growth.

• It brought air into the lungs to provide needed oxygen for the body.

• It transported blood through the body to bring oxygen and nutrients to cells.

• It worked with the skeletal system to produce movement.

4. How does the skeletal system work with the muscular system in the human body?

• The skeletal system circulates blood through the arteries and veins that run through muscles.

• The skeletal system removes waste products that build up in muscles during exercise.

• The skeletal system provides support and solid structures where tendons and muscles can attach.

• The skeletal system brings oxygen to muscle cells and carries away carbon dioxide.

5. The muscle that pumps blood throughout your body is

• cardiac muscle

• valentine muscle

• smooth muscle

• skeletal muscle

6. Where would you find an involuntary muscle?

• in your arms

• in your stomach

• in your mouth

• in your toes

7. Why are voluntary muscles also known as skeletal muscles?

• They are part of your skeleton

• They contain bone fragments

• They make your skeleton move

• They give your body its form and structure

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

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

9. Which best describes the purpose of the muscular system?

• The muscular system carries messages from the brain to the bones to move the body.

• The muscular system keeps the bones strong and protects them from being broken.

• The muscular system allows movement of bones and helps maintain posture.

• The muscular system produces energy the body needs to be able to move.

10. Which system produces red blood cells?

• skeletal

• nervous

• digestive

• circulatory
