Human Anatomy
11 Body Systems
Human Anatomy
 There are 11 systems that interact to make-up
the human body and its functions.
 The most commonly know systems are the
Skeletal, Muscular, Cardiovascular, Respiratory,
Nervous, Reproductive, and Digestive systems.
 The others are the Integumentary, Endocrine,
Immune, and Excretory systems.
Skeletal System
 Consists of Bones
and Joints
 Major function is to
provide the body with
support and
protection.
 Divided into Axial
and Appendicular
sections.
Muscular System
 Consists of muscles,
tendons and ligaments.
 Three types of muscle.
Skeletal, smooth, and
cardiac muscle.
 Tendons connect
muscles to bones.
 Ligaments connect
bones to bones.
Cardiovascular
 Consists of heart,
blood vessels and
blood.
 Heart has four
chambers.
 Three types of blood
vessels; arteries,
veins and capillaries.
Respiratory System
 Major organs are
lungs and bronchi.
 Functions as bodies
gas exchange
system.
 Provides cells with
oxygen.
 Removes carbon
dioxide.
Nervous System
 Consists of Brain,
Spinal Chord and
nerves.
 Controls both
somatic and
autonomic body
functions.
Reproductive System
 Consists of male and
female reproductive
organs.
 Organs in the body
responsible for
producing gametes.
 Female organs able
to support the growth
and development of
a fetus.
Digestive System
 Major organs are
esophagus, stomach,
intestines, liver, and
colon.
 Breaks down food
into molecules that
the body can use for
energy and other
functions.
Integumentary System
 Skin, hair and nails.
 Controls body
temperature.
 Protects the body
from outside dangers
(bacteria, disease,
temperature, etc.).
Endocrine System
 Made up of a series
of glands.
 Produce the
hormones that
regulate body growth
and development.
Immune System
 Consists of glands
and lymph nodes.
 Filter blood and
remove harmful
substance from the
body.
Excretory System
 Consists of kidneys,
ureter, and bladder.
 Removes urine from
the body.
