describe apocrine sweat glands
Give this one a try later!
very special b/c confined to axillary (armpit), anal, and genital areas; glands
get ducting through hair follicles --> don't become active until puberty
(once armpit and pubic hairs are made), make organic sweat made up of
proteins, lipids, and nucleic acids = major histocompatibility complex (MHC)
how does the skeletal system facilitate the storing of minerals in the body?
Give this one a try later!
, main minerals found in bone are calcium (99% of calcium is stored in the
body) and phosphorus; minerals are consumed and absorbed out of our
food, then deposited/withdrawed from our mineral storage
describe connective tissue proper
Give this one a try later!
fibrous CT, connects stuff, few cells + lots of extracellular matrix, abundant
w/ collagen fibers
what is passive transport?
Give this one a try later!
going with the gradient, does not require energy, like "rolling downhill" b/c
molecules do what they want (want to find open spaces), moves from high
to low concentration as the natural movement
how does the integument SHUNT to regulate body temp?
Give this one a try later!
, body pumps and moves blood to different parts of body depending on
temp, ex: during summer, body sends blood to extremities to cool surface
then flow back one (like radiator sending hot blood in to cool down and
recirculate) so clothes and watches can fit tighter; during winter, body
brings blood back in to maintain temp. of vital organs so fingers, feet, and
head get cold
describe the subdivisions of loose connective tissue
Give this one a try later!
areolar CT = most widely distributed CT, strong but flexible, really good
blood supply (more fluids + more adipocytes), found underlying epithelium
in trachea + other organs
adipose CT = lots of adipocytes (fat cells that are like a balloon with
nucleus pushed to edge by fat droplet), richly vascularized, glycogen gets
stored as adipose once storage runs out
how does the integumentary system protect?
Give this one a try later!
protects and divides our external environment from internal environments,
ex: protects against UV radiation and dehydration
describe the stratum granulosum (granules)
