1

Simply differentiate Regeneration

Viability
of surrounding connective tissue Blood,Bone,Cartilage
connective tissue proper

2

Simply differentiate Healing

Occurs when the basic Tissue structure has been
altered
it involves both regeneration and the formation of fibrous
or scar tissue

3

Removal Debris (scar formation)

Acute inflammation

4

Angiogenesis (scar formation)

the formation of new blood vessels

5

Formation of Granulation Tissue

(1)Newly formed Capillaries proliferating fibrillates,a and
residual inflammatory cells

(2)new connective tissue and tiny blood vessels that form on the surfaces of a wound during the healing process.

6

Scar Remodeling

Scar tissue is not inactive,the collagen is continually replaced

7

Maturation of a Scar

collagen content of a scar gradually increases overtime

8

Contraction and Strengthening

decreases the size of the scar
remaining cells of the organ to function with maximal
effectiveness

9

Tensile Strength of a Scar

Depends on the amount of collagen and the tensile strength of
an integumentary scar increases over time

10

*Edema

*Caused by an imbalance of opposing pressure
The space between the cells and vessels

11

Hydrostatic Pressures

Push:a pressure that tries to force the fluid out of that space

12

Oncotic Pressure

Pull:A pressure that pulls fluid into that space

13

Hematomas

Blood filled swelling
A hematoma or haematoma is a localized collection of blood outside the blood vessels, usually in liquid form within the tissue.

14

*Hemostasis

Blood in fluid state in normal vessels whole forming A Clot at the site of Vascular Injury

15

*Thrombosis

A blood clot forming within a normal,intact vessel is thrombus

16

*Pathogenesis

Endothelial Injury
The pathogenesis of a disease is the biological mechanism (or mechanisms) that lead to the diseased state

17

Mural Thrombosis

The formation of a thrombus within the chambers of the heart

18

Propagation (Fate of the Thrombus)

The Thrombus increases in size

19

Dissolution(Fate of the Thrombus)

The Thrombus dissolves opening up the vessel

20

Embolization(Fate of the Thrombus)

The Thrombus breaks free and moves through the vessels

21

Organization (Fate of the Thrombus)

Induces inflammation and the Thrombus is built into the wall

22

Infarction

(1)Blockage causing Ischemic NECROSIS

(2)the obstruction of the blood supply to an organ or region of tissue, typically by a thrombus or embolus, causing local death of the tissue.

23

*Edema fluid builds in

3rd interstitial space
Causes a compression of surroding tissue nerve Parathesia blood vessel blood flow necrosis

24

Hypercoagulability

Caused by visceral malignancies,sickle anemia,o r al contraceptives,cigarette smoking

25

Venous Stasis

Usually results from immobilization
