The document describes the key components and functions of the integumentary system in humans. It discusses the three layers of skin - epidermis, dermis, and hypodermis. The dermis contains sweat glands, oil glands, hair follicles, and blood vessels. Hair, nails, and glands like sweat and oil glands are also part of this system, which acts as a protective barrier for the body.

12. THE
INTEGUMENTARY
SYSTEM

13. THE INTEGUMENTARY SYSTEM
 Is composed of organs that form
the external covering of the body
and protect it from many threats
such as infection, abrasion,
chemical assault and radiation
damage.
 In humans the integumentary
system comprises the skin and its
accessory structures including the
hair, nails and glands.

14. The Skin

15. THE SKIN
 The skin is composed of the
outer layer called epidermis, the
middle layer called dermis and
the innermost layer called
subcutaneous layer.
 Is the largest organ of the body, weighing more than twice the
brain.

16. Epidermis

Layer

17. Layers of the Skin
1.Epidermis is the outermost layer of the skin.
 Pores are tiny openings of the
skin that serve as passageway of
sweat and oils.
 Melanin is a substance in your
body that produces hair, eye and
skin pigmentation. The more
melanin you produce, the darker
your eyes, hair and skin will be.
 Keratin is a protein that helps support your skin, heal wounds and
keep your nails and hair healthy.

32. The Hair
Hair is made up of keratin.
Hair serves many
functions:
 The hair in the nose “cilia”
and ears filter the dust
particles.
 Eyebrows deflect sweat to
protect the eyes.

33. Nails
 Are also made up of
keratin.
 Fingernails grow faster
compared to toenails.
 It protects sensitive
fingertips and toes from
injury.

34. Glands
 The main glands of the skin: sweat gland and oil gland
Sweat glands help in the excretion of wastes by releasing the excess
water and salts produced by the body. They also function in the
regulation of the body temperature.
Oil glands, also called as sebaceous glands which secrete an oily
substance called sebum. Too much production of sebum may clog the
pores and may result to infection just like pimples.
