Q

what is the function of the hypodermis?

A

to produce insulation and store energy

17
Q

why does body odor occur?

A
  • bacteria thrives in the moisture of sweat and breaks down the chemicals
18
Q

how does the integumentary system contribute to homeostasis in the body?

A
  • the integumentary system regulates temperature, prevents water loss, produces vitamin D, and provides a barrier against the outside world.
19
Q

how does vitamin a help the skin?

A
  • vitamin a is needed to prevent skin damage, and potentially skin cancer
20
Q

how does aging effect the integ. system?

A
  • there is less collagen being produced, which can lead to thinner skin and reduced elasticity.
21
Q

what cells are responsible for prodcing melanin?

A
  • melinocytes
22
Q

what are the tissues that do not contain blood?

A
  • avascular
23
Q

what role do sensory receptors play in the integ. system?

A
  • it detects enviromental changes, detects pain and pressure
24
Q

what percentage is melanocytes and keratinocytes made up of?

A

keratinocytes: 90%
melanocytes: 8%

25
Q

how do you know if a part of your body has a lot of melanin?

A
  • moles and freckles means there is a lot of melanin in a specific spot.
