1

6 functions intergumentary system

protection
thermoregulation
Vit D production
sensation
absorption
excretion

2

5 ways skin protects us

physical barrier
sebum anti-microbial
sweat - contains lysozyme
desquamation removes microbes
nerve sensors induce protective reflexes

3

2 control centres for body temp are

hypothalamus
vasomotor centre of medulla oblongata

4

what controls sweat glands/BVs to regulate body temp

ANS

5

other heat producing organs are

liver
muscles
digestive tract

6

heat loss also via

respiration

7

heat maintenance via which tissue

adipose - insulation

8

what is a pyrogen

fever-inducing substance

9

normal body temp

36.7 C

10

hypothermia

rectal temp below 35 - death @ 25C

11

hyperthermia

above 37.5, death @44C

12

how is vit C synthesized

UV light activates Vit D precursor in skin
kidneys turn precursor to CALCITRIOL

13

effect of calcitriol on body

acts as hormone
increases uptake of calcium and phophorous in blood
supports bone density

14

vit D stored in

liver

15

skin absorbs

lipid-soluble molecules
Vits A, D, E, K
meds - corticostaeroids
O2, CO2
toxins

16

skin excretes

salt
water
urea
ammonia
