Question

Explain how the skin contributes to immune protection, thermoregulation, and protection against damage caused by ultraviolet radiation. Be sure to clearly describe all the cells involved. This answer should contain at least 20 clearly stated anatomical facts

Answer 1

Yes skin is the largest sensory organ in human being.

1. Sebaceous gland in our skin produce sebum that has fatty acid they provide protection against the bacteria giving immunity
2. The sebum contain fatty acids that has antifungal property
3. Lipids present in sebus prevent heat loss and cause thermoregulation.
4. The sweat from the sweat glands of the skin will helps in reduction of body temperature
5. Skin cover the body with epidermis dermis layers and protect from infection
6. Lysozyme secreted by skin helps in destruction of bacteria giving immunity
7. The stratum corneum protect our skin From bacterial toxin and helps in immunity and prevent their invasion
8. In injury keratinocytes secrete cytokines like alpha tumor factors and interleukin causing immunological response
9. Antimicrobial peptides like beta defensins are produced by skin
10. Stratum corneum if skin has melanocytes that cause protection against UV radiation
11. Skin prevent energy loss by convection
12. Skin prevent energy loss by conduction
13. Skin prevent energy loss by radiation
14. Skin prevent energy loss by evaporation
15. Melanin absorb the UV radiation and protect skin from it
16. Prevent injury to underlying structure of body
17. Lipid in skin helps in thermoregulation
18. In injury the impact of infection will not occur due to constriction of skin
19. Gamma interferon are secreted by skin for immunity
20. Using UV rays vitamin D is synthesized in skin which aid in immunity
