• True

• False

The first thing that happens when a bone breaks is...

• New bone forms

• Bleeding 

• Swelling

• Immune response

Phagocytes, or white blood cells, contribute to bone healing by...

• Removing any germs that entered the blood clot area

• Removing all broken bone tissue

• Adding new bone to the fractured area

Osteoclasts participate in the bone healing/ remodeling process by...

• Adding new bone fragments

• Removing old bone fragments

• Cleaning up the germs from the wound

The first step to REPLACING the broken bone is through the chondroblasts laying down:

• bone

• ligaments

• fibrocartilage

• tendons

The fibrocartilaginous tissue added to the area of injury is called a _____________.

• Bone

• Soft callus

• Hard callus

• Bony callus

The soft callus turns into a ________ through ossification.

• Bony callus

• Hard callus

• Joint callus

A slight bump remains after the bone remodeling process because the __________ did not remove all of the bony callus.

• Osteoblasts

• Osteoclasts

• Chondroblasts

• Osteocytes

Which of the following would NOT contribute to issues with bones healing correctly?

• Age

• Poor blood supply

• Infections
