Wound Healing in the Integumentary System

What is the primary goal of the healing process?

• To prevent infection

• To reduce pain

• To fill the gap created by tissue destruction and restore structural continuity

• To increase blood flow

Which phase of wound healing aims to remove the injury-causing agent?

• Proliferative phase

• Remodeling phase

• Inflammatory phase

• Epithelialization phase

What are the signs of inflammation?

• Redness, swelling, heat, pain, and loss of function

• Bleeding, bruising, itching, and dryness

• Fever, chills, sweating, and fatigue

• Numbness, tingling, coldness, and stiffness

What is the role of leukocytes during the inflammatory phase?

• To form granulation tissue

• To secrete growth factors

• To engulf and degrade bacteria and cellular debris

• To synthesize collagen

What marks the beginning of the proliferative phase?

• The formation of scar tissue

• The arrival of fibroblasts

• The arrival of leukocytes

• The reduction of inflammation

What is the main focus during the proliferative phase?

• Removing the injury-causing agent

• Building new tissue to fill the wound space

• Forming scar tissue

• Reducing pain and swelling

What is granulation tissue?

• Newly developed capillary buds

• A type of scar tissue

• A type of leukocyte

• A type of collagen

What is epithelialization?

• The formation of new blood vessels

• The regeneration, migration, proliferation, and differentiation of epithelial cells

• The synthesis of collagen

• The reduction of inflammation

When does the remodeling phase begin?

• After six months

• After one month

• After about three weeks

• Immediately after injury

What percentage of tensile strength can scar tissue achieve by the end of three months?

• 60-70%

• 70-80%

• 80-90%

• 50-60%
