Functions of the Skeleton

What is one of the main functions of the skeletal system related to body structure?

• Digestion – aiding in the breakdown and absorption of food

• Circulation – moving blood throughout the body

• Respiration – facilitating the exchange of oxygen and carbon dioxide

• Support – keeping the body upright and providing a framework for muscle and tissue attachment

Which part of the skeletal system offers protection to the brain?

• Femur

• Cranium

• Humerus

• Pelvis

How do bones contribute to movement?

• By protecting internal organs

• By forming joints and acting as levers for muscles to pull on

• By storing minerals

• By producing red blood cells

Which bones contain marrow that produces blood cells?

• Tibia and Fibula

• Pelvis, Sternum, Humerus, and Femur

• Carpals and Metacarpals

• Radius and Ulna

What minerals do bones store?

• Vitamin D, Vitamin B12, Vitamin C

• Protein, Carbohydrates, Fats

• Glucose, Fructose, Sucrose

• Calcium, Iron, Potassium, Phosphorous

What role do ligaments play in the skeletal system?

• Connecting muscles to bones

• Protecting internal organs

• Connecting bones to bones at joints

• Producing red blood cells

How does the skeletal system contribute to the production of blood cells?

• By filtering blood

• By storing minerals necessary for blood cell production

• By providing a site for muscle attachment

• By housing the bone marrow, which produces blood cells

Which of the following is a function of the skeletal system?

• Regulating body temperature

• Facilitating movement

• Producing hormones

• Absorbing nutrients

Which of the following best describes the function of the vertebral column?

• Protection of the heart and lungs

• Production of red blood cells

• Support for the body and protection of the spinal cord

• Storage of minerals

What is the role of cartilage in the skeletal system?

• To produce blood cells

• To store minerals

• To reduce friction and absorb shock at joints

• To connect muscles to bones
