damaged tissue is replaced by
the same type of cells. The new tissue completely restores the damaged area to its normal state.

Q

damaged tissue is replaced with
dense fibrous connective tissue or scar tissue. This can interfere with or inhibit the normal function and architecture of the underlying organ or tissue. Examples include fibrosis in the lungs, liver, brain, and heart.

Q

OBJECTIVE : Prevent further injury.

■ Damaged cells release inflammatory chemicals, increasing capillary permeability
■ White blood cells (WBCs) and clotting proteins seep into the injured area.
■ Platelets migrate to form a fibrin clot, which seals the wound and prevent blood loss
■ Immune cells (neutrophils and macrophages) accumulate to remove debris and bacteria
■ Symptoms include swelling,redness, pain, and heat

A

Q

Objective: Supply cells and nutrients
for remodeling.

Process:
■ New blood vessels form around the wound, creating granulation tissue—delicate pink tissue with new capillaries.
■ Connective tissue cells (fibroblasts) produce collagen fibers and extracellular matrix.
■ Granulation tissue facilitates wound closure as fibroblasts synthesize collagen.
■ Myofibroblasts pull the wound edges together.

A

Granulation tissue forms

Q

Objective: Regenerate surface epithelium and finalize wound
closure.

Process:
■ The surface epithelium regenerates, thickens, and makes its way between granulation tissue and the scab.
■ The scab eventually detaches, leaving behind a scar.
■ The fibrous tissue matures to form a scar, which may be visible or invisible depending on the severity of the wound.
■ During remodeling, the new tissue matures to more closely resemble the surrounding mature tissue.

19
Q

→ Repair of superficial wounds or clean surgical incisions approximated by surgical supports. Involves inflammation, granulation, and maturation stages.

A

Primary Union (First Intention)

20
Q

→ Autoimmune disorder
→ Rapid skin cell production,
resulting in red lesions covered with dry, silvery scales; triggered by trauma, infection, hormonal changes, or stress

A

Psoriasis

20
Q

→ CAUSE; Fungal infection
→ SYMPTOMS: Itchy, red peeling skin
between the toes

A

Athlete’s Foot

21
Q

➔ Caused by bacteria,viruses,orfungi.

A

INFECTIONS

21
Q

→ Cause: Exposure to chemicals (e.g.,
poison ivy)
→ Symptoms: Itching, redness, swelling,
possibly blistering

A

Contact dermatitis

21
Q

→ Repair of large wounds, abscesses, ulcerations, or necrosis. Involves both regeneration and scarring, with more intense inflammation, abundant granulation tissue, extracellular matrix accumulation, and large scar formation.

A

Secondary union (Second Intention)

22
Q

→ : Inflammation of hair follicles
→ : Painful, swollen bumps

A

Boils (furuncles)

23
Q

→ Cause: Clusters of boils, often due to
Staphylococcus aureus
→ Symptoms:Multiple interconnected boils

A

Carbuncles

23
Q

→ Herpes Simplex Virus 1
→ Fluid-filled blisters
around lips and mouth, itching, and stinging

A

Cold sores (fever blisters)

24
Q

→ Cause: Staphylococcus or
Streptococcus bacteria
→ Symptoms: Pink fluid-filled lesions
with yellow crusts, primarily around mouth and nose.

A

Impetigo

25
Q

Tissue damage and cell death caused by heat, electricity, UV radiation, or chemicals

A

BURNS

26
Q

Result in loss of body fluids and infection from the invasion of bacteria

A

burns

27
Q

Extent of a burn is estimated using the?

A

rule of nines

28
Q

→ Epidermis and superficial part of dermis are damage
→ Skin is red, painful, and blistered
→ May result in scarring
→ Regrowth of the epithelium can occur → Caused by hot water, flames,
chemicals, or electricity.

A

Second-degree burn (partial-thickness burn)

28
Q

Only epidermis is damaged
→ Skin is red and swollen
→ Heals in 2-3 days

A

First-degree burn (superficial burn) →

29
Q

→ Destroys epidermis and dermis; burned area is painless
→ Requiresskingrafts,asregeneration is not possible
→ Burned area is blanched (gray-white) or black

A

Third-degree burn (full-thickness burn)

30
Q

→ Extends into deeper tissues (bone, muscle, tendons)
→ Appears dry and leathery
→ Requires surgery and grafting
→ May require amputation

A

Fourth-degree burn (full-thickness burn)
