1. Skin and body membranes

2. Body Membranes Function of body membranes Cover body surfaces
Line body cavities
Form protective sheets around organs

3. Wound Healing
Hemostasis
Inflammation
Proliferative
Remodeling

4. Cutaneous Membrane
Cutaneous membrane = skin

5. Cutaneous Membrane

6. Mucous Membrane
Lines body cavities that open to the exterior

7. Mucous Membrane

8. Serous Membranes
Lines body cavities that are not open to the exterior

9. Serous Membranes
Visceral layer:
Parietal layer:

10. Serous Membranes

11. Serous Membranes
Pleura
Pericardium

12. Connective Tissue Membrane
Lines joints
Secretes a lubricating fluid
(Synovial membrane)

13. Connective Tissue Membrane

14. The Integumentary System
The skin and the associated organs of sweat and oil glands, hairs, and nails make up the Integumentary system

15. Metastasis – spread of cancer to other parts of body

16. Cancer Treatment Videosw
LMYc

17. Radiation Damages cellular DNA Directed at specific area
Over days or weeks
Side effects occur at treatment area

18. Chemotherapy
Chemicals developed to have greatest effect on quickly dividing cells
Healthy cells also damaged/killed
Weakened immune system
Nausea
Hairloss
Weight loss
Anemia

19. The skin Fun Facts: Avg. makes up about 9-11 lbs. or 7% of your weight
Regenerates every days
Every minute you lose 30,000-40,000 dead skin cells

20. Protection

21. Maintaining Body Temp

22. Excretion

23. Irritability/Sensitivity

24. Skin Structure (EDH)
Epidermis (epithelial) Dermis (fibrous) Hypodermis (subcutaneous – fat)

25. Skin Structure (EDH)

26. Skin Structure
Epidermis—outer layer
Stratified squamous epithelium

27. Skin Structure
Dermis
Hypodermis is deep to dermis

28. 5 Layers of the Epidermis (CLGSB)
Stratum corneum
Statum lucidum
Stratum granulosum
Stratum spinosum
Statum basale

29. 5 Layers of the Epidermis (CLGSB)
Stratum basale

30. 5 Layers of the Epidermis (CLGSB)
Stratum spinosum

31. 5 Layers of the Epidermis (CLGSB)
Stratum granulosum

32. 5 Layers of the Epidermis (CLGSB)
Stratum lucidum

33. 5 Layers of the Epidermis (CLGSB)
Stratum corneum

35. Specialized Epidermal Cells
No blood vessels found in epidermis
Very few sense receptors

36. Specialized Epidermal Cells
Melanocytes –
Keratinocytes –
Merkel cells –
Langerhans cells –
