• Takes in oxygen

• Excretes waste from the body

1. Marrow is found in the bones. What is the function of marrow in the skeletal system?

• To produce cartilages

• To produce blood cells

The skeletal system has six main functions in the body. Which of the following statements does not describe a function of the skeletal system?

• It stores fats and minerals for later use

• It provides structure and shape for the body

• It produces blood cells and releases them into the body

• It helps to maintain homeostasis through blood circulation

Complete the table which shows the body structures affected by the different muscles.

Groups:

(a) cardiac muscle

,

(b) skeletal muscle

,

(c) smooth muscle

• Body Part - Stomach

• As it contracts and relaxes, it moves the bones it is attached to.

• Body Part - Leg

• Its contractions move food through the digestive system.

• Body Part - Heart

• Its rhythmic contractions cause the heart to beat.

3. There are three types of muscle tissue. Which statement correctly describes the types?

   
   

• Cardiac, skeletal, and smooth muscles are all involuntary

•  Cardiac muscles contract the heart. Skeletal muscles move the bones. Smooth muscles are found in the arteries and veins

• Cardiac muscles contract the heart. Smooth muscles move the bones. Skeletal muscles are found in the arteries and veins.

• Cardiac, skeletal, and smooth muscles are all voluntary.

Ligaments connect which of the following structures?

• Tendons to joints

• Muscle to muscle

• Muscle to bone

• Bone to bone

Why do cardiac muscles differ from skeletal muscles?

• They are attached to bones

• They are voluntary and contract when we decide.

• They work without conscious control and never tire.

• They are found in the digestive system.

What would most likely happen if a person’s cartilage wore away completely?

• Their muscles would stop contracting.

• Their bones would rub together, causing pain and stiffness.

• Their ligaments would become stronger.

• Their body would not be able to produce red blood cells.

Which type of muscle is found in the walls of the stomach and intestines?

• Skeletal muscle

• Cardiac muscle

• Smooth muscle

• Voluntary muscle

Which of the following is NOT a function of the skeletal system?
