1. Parts and Functions of
Integumentary System

2. What system is shown?
SKELETAL SYSTEM
What is its function?
 Framework of our body
 Support of the body
 Protection of soft organs
 Movement due to
attached skeletal
muscles
 Storage of minerals and
fats
 Blood cell formation

3. Muscular System
is responsible for the
movement of the human
body.
Attached to the bones of the
skeletal system are about 700
named muscles that make up
roughly half of a person's
body weight. Each of these
muscles is a discrete organ
constructed of skeletal
muscle tissue, blood vessels,
tendons, and nerves.
Function

4. is a series of
organs
responsible for
taking in oxygen
and expelling
carbon dioxide.

8. The integumentary system consists of
the skin, hair, fingernails, glands and
nerves.
The main function of the
integumentary system is to act as a barrier
to protect the body from the outside world.
It also functions to retain body fluids,
protect against diseases, eliminate waste
products and regulate body temperature.

9. Skin: the thin layer of tissue
forming the natural outer covering
of the body of a person or animal.

10. The skin is only a few
millimeters thick yet is by far
the largest organ in the body.
... Skin forms the body's outer
covering and forms a barrier to
protect the body from
chemicals, disease, UV light,
and physical damage.

11. the skin consists of two layers:
the epidermis and the dermis.
Beneath the dermis lies the
hypodermis or subcutaneous fatty
tissue.
The skin has three main functions:
1.protection,
2.regulation and
3.sensation.

12. Epidermis. The epidermis is the most
superficial layer of the skin that covers
almost the entire body surface. ...
Dermis. The dermis is the deep layer of the
skin found under the epidermis.
These skin cells produce the protein
keratin, the basic structural component of hair
and nails. Found in the epidermis, these cells are
part of the immune system's defense against
infection. These epidermal cells produce
melanin, the pigment that gives skin its color

13. Hairs(or pili; pilus in the singular) are
characteristic of mammals.
The functions of hair include
1.protection,
2.regulation of body temperature, and
3.facilitation of evaporation of
perspiration;
hairs also act as sense organs.
Hairs develop in the fetus as epidermal
down growths that invade the underlying
dermis.

15. A nail is a horn-like envelope
covering the tips of the fingers and toes in
most primates and a few other mammals.
Nails are similar to claws in other animals.
Fingernails and toenails are made of a tough
protective protein called keratin.
they are formed of keratinized
epidermal cells and occur on the finger and
toes. Consist of a visible area (body) and the
root (embedded in the dermis).

17. Glands:. These glands secrete their contents
to the exterior unlike endocrine which secrete
their contents directly into blood.

18. There are three exocrine (conts ducts) glands:
1. Sebaceous glands: produce oil (sebaum) which keeps the skin
oily. The glands are branched and attached to the hair follicle.
Blockage of the gland causes acne.
2.Sudoriferous(sweat) gland: produce sweat or perspiration
composed of water, salt, urea and uric acid. They are coiled and
tubular shaped and of two types: Eccrine (found on forehead, back of
palm and soles), and Apocrine (larger that eccrine, found in pubic
regions and secrete into hair follicles). Mammary glands: are
specialized form of sudoriferous gland secrete milk.
3. Ceruminous glands: found only in the external auditory canal
where they secrete cerumen (earwax). Cerumen is an insect repellant
and also keep the eardrum (tympanic membrane) from drying out.
Excess amount may block.

19. Answer the following questions:
1 What can happen if a part of the body is
not covered with skin?
2. What can happen if your sweat glands
do not produce perspiration?

20. ‘Why do you think this person suffers such?”

21. Integumentary System
forms the
body's outer
covering and
forms a
barrier to
protect the
body from
chemicals,
disease, UV
light, and
physical
damage.
1.protection,
2.regulation of
body temperature,
and
3.facilitation of
evaporation of
perspiration;
act as sense
organs.

umbrella or other
protective cover when
walking under the
sun?
