Anatomy and the
Organ Systems
Anatomy – the study of the
structure of an organism
 Recall… Animals are multicellular
organisms with specialized cells grouped
into tissues. In most animals, tissues are
organized into organs, and the
combination of organs make up the 11
organ systems
 CELLSTISSUESORGANSORGAN
SYSTEMS
1) Muscular System
 Main components:
Skeletal Muscles
 Main functions:
Movement and
Locomotion
2) Skeletal System
 Main Components:
Skeleton (bones,
tendons, ligaments &
cartilage)
 Main Function: Body
support, protection of
internal organs
3) Digestive System
 Main Components:
Mouth, pharynx,
esophagus, stomach,
intestines, liver,
pancreas & anus
 Main Functions:
Food processing
(ingestion, digestion,
absorption &
elimination
4) Circulatory System
 Main Components:
Heart, blood vessels
(more later…) &
blood
 Main Functions:
Internal distribution
of materials (i.e.
oxygen, nutrients…)
5) Respiratory System
 Main Components:
Lungs, trachea, and
other breathing tubes
 Main Functions: Gas
exchange (Oxygen
uptake and Carbon
Dioxide disposal)
6) Excretory System
 Main Components:
Kidneys, ureters,
urinary bladder, and
urethra
 Main Functions:
Disposal of wastes
(metabolic), and
regulation of some
blood characteristics
(i.e. salt content)
7) Immune/Lymphatic
System
 Main Components:
Bone marrow, lymph
nodes, thymus,
spleen, and white
blood cells
 Main Functions:
Body defense
8) Nervous System
 Main Components:
Brain, spinal chord,
nerves, and sensory
organs (eyes, ears..)
 Main Functions:
Coordination of body
activities, stimulus
detection and
responses
9) Endocrine System
 Main Components:
Pituitary, thyroid,
pancreas & other
hormone secreting
glands
 Main Functions:
Coordination of body
activities (i.e.
digestion,
metabolism…)
10) Reproductive System
 Main Components:
Ovaries, testes and
other sex organs
 Main Functions:
Reproduction
11) Integumentary System
 Main Components:
Skin, hair, nails etc.
 Main Functions:
Protection against
injury, infection, and
drying out
