KNOW THE DIFFERENCE BETWEEN THE 4!
Human Body Systems
• Nervous System – Recognizes and coordinates the
body’s response to changes inside and outside the
body
• Integumentary System – Skin! Guards against
infection and UV radiation. Regulates body
temperature
• Immune/Lymphatic Systems – Protects body from
disease
Human Body Systems
• Muscular System – Helps the skeletal system to
produce voluntary movements. Helps circulate
blood and move food through digestive system
• Circulatory system – Transports oxygen, nutrients
and hormones to cells. Regulates body temperature.
• Skeletal System – Supports the body. Protects
internal organs
Human Body Systems
• Respiratory System – Brings in oxygen needed for
cellular respiration. Removes excess CO2
• Digestive System – Breaks down food, absorbs
nutrients, eliminates waste
• Excretory System – Eliminates waste products from
the body
Human Body Systems
• Endocrine System (hormones) – Controls growth,
development and metabolism
• Reproductive System – Produces offspring. Females
nurture and protect developing embryo
Organization of the Body
•
Cells – Basic units of life, structure and function
•
Tissues – Group of cells performing a specific function

IV.
Epithelial Tissue
Connective Tissue
Nervous Tissue
Muscle Tissue
•
Organs – Group of tissues that work to perform a single function
•
Organ Systems – Group of organs that perform closely related
functions
• EXAMPLE – Stomach and Large Intestines are apart of the Digestive
System
Epithelial Tissue
What does it do?
• Protects, absorbs and excretes materials
Where can it be found?
• Skin, lining of digestive system, certain glands
Connective Tissue
What does it do?
• Binding of epithelial tissue to structures, support and
transport of substances
Where can it be found?
• Under skin, surrounding organs, blood, bones
Nervous Tissue
What does it do?
• Receives and transmits nerve impulses
Where can it be found?
• Brain, spinal cord, and nerves
Muscle Tissue
What does it do?
• Voluntary and involuntary movements
Where can it be found?
• Skeletal muscles, muscles surrounding digestive
tract, blood vessels and the heart
Homework
• Read Section 32.1 on P. 922
• Label the blank skeleton with as many bones as you
can
• Winner gets a prize (so don’t try and help each other
out)
Flashcards!
• On one side, the type of tissue
• On the other side, its action and 1 place where it can
be found in the human body
