Anatomy Physiology
Remember cells with similar
functions combined to make
tissues
4 types of tissue:
• 1. Epithelial
tissue
• 2. Connective
tissue
• 3. Muscular
tissue
• 4. Nervous
tissue
Epithelial tissue covers the
body surface, lines the body
cavities and forms glands
Connective tissue binds and
supports the body (including
bones, adipose, blood, lymph)
Muscular tissue moves the
body and its parts (skeletal,
smooth, and cardiac)
Nervous Tissue receives
stimuli and transports signals
(Central and peripheral)
Two or
more
tissues
working
together to
perform a
particular
function
make an
organ
Groups of organs that cooperate to
carry out a process make an organ
system
The human body has 11 organ
systems
2 protect the
body from
disease:
Integumentary
and Lymphatic
(Including
immune)
Integumentary System-- Barrier
from disease
Integumentary System
• Skin, Hair, Nails, Sweat and Oil Glands
Lymphatic System (immune
system)
Fights disease once foreign objects enter
the body
Lymphatic System
• Structures: White blood cells, Thymus,
Spleen, Lymph nodes
2 for structure, support,
movement: Skeletal and
Muscular
Skeletal System
• Supports body, Provides protection
Skeletal System Cont
• Structures: Bones,
Teeth, Cartilage,
Ligaments, Tendons
Muscular System
• Provides structure,
Responsible for
voluntary movement,
circulates blood,
moves food through
digestive system
Muscular System Cont.
• Structures: Skeletal muscle, Smooth
muscle, cardiac muscle
4 for acquiring materials and
energy: Skeletal, Muscular,
Digestive and Respiratory
Digestive
System-Converts food
to usable
materials
Digestive System Continued
• Structures: Mouth,
Pharynx, Esophagus,
Stomach, Intestines
Respiratory
System
responsible for
gas exchange
(take in Oxygen
put out Carbon
dioxide)
Respiratory System Continued
• Structures: Lungs, Pharynx, Larynx,
Trachea
3 Excrete Waste:
Integumentary, Respiratory,
Excretory
Excretory
System
eliminates
waste from
body through
the
production of
urine
Excretory System Cont.
• Structures: Kidneys, Ureters, Bladder,
Urethra
1 transport materials through
the body: Circulatory
Circulatory System
• Distributes materials
throughout the body
Circulatory System Cont.
• Structures: Heart, Blood vessels, Blood
2 Respond and Coordinate
body Activities: Nervous and
Endocrine
Nervous System
coordinates the
body’s response to
environment
through electrical
impulse and short
range chemical
signals
Nervous System Continued
• Structures: Brain, Spinal Cord, Nerves
Endocrine
System
coordinates the
body’s response
to environment
through long
range chemical
signals called
hormones
Endocrine System Continued
• Structures: All glands (Hypothalamus,
Pituitary, Thyroid, Pancreas, Ovaries,
Testes)
2 Systems produce offspring:
Endocrine and Reproductive
Reproductive System
produces sex cells, fertilizes,
nurtures and protects embryo
and developing fetus
Reproductive System Cont.
• Structures:
– Male: Testes, Epididymis, Vas Deferens, Urethra,
Penis
– Female: Ovaries, Fallopian tubes, uterus, Vagina
All body systems work
together to maintain
homeostasis
Homeostasis is the
maintenance and control of a
stable internal environment
Examples: Body
Temperature, Blood sugar
levels, Oxygen levels, many
more functions
