Notes
• On Page 34– You will take notes over
the following PowerPoint. The phrases
in red need to be copied down. And
write down any excess information you
feel is important.
Essential Question
PG 34
How do animal systems interact to
defend the body?
Standard
B.10A - describe the interactions that occur among systems
that perform the functions of regulation, nutrient
absorption, reproduction, and defense from injury or illness
in animals
SYSTEMS INVOLVED
ILLNESS
Integumentary
(1st
line of defense)
Immune
(2nd
line of defense)
Circulatory
INTEGUMENTARY SYSTEM
• Main Parts:
–Skin
–Hair
–Nails
–Sweat and
Oil glands
INTEGUMENTARY SYSTEM
• Main Functions:
–Holds in water
–Keeps out foreign objects
–Helps control body temperature
The Integumentary system acts as a
wall or barrier to any outside
threats!
Occasionally threats make it past the wall…
Functions of the Integumentary
System (skin)
•
Protection
– First line of defense against
•
•
Bacteria
Viruses
– Protects underlying structures from
•
•
•
Ultraviolet (UV) radiation
Dehydration
Body temperature regulation
– If too hot
•
•
Dermal blood vessels dilate
Vessels carry more blood to surface so heat can
escape
– If too cold
•
•
Dermal blood vessels constrict
Prevents heat from escaping
Functions of the Integumentary
System (cont.)
•
Vitamin D production
– Needed for calcium absorption
•
Sensation
– Sensory receptors (nerves)
•
Excretion
– Small amounts of waste products
are lost through perspiration (sweat)
IMMUNE SYSTEM
• Main Parts:
–Antibodies (protective proteins)
–T-cells (White Blood Cells)
–B-cells (White Blood Cells)
IMMUNE SYSTEM
• Main Functions:
–B-cells produce antibodies that attack
pathogens (foreign invaders) in the
blood
–T-cells attack invaded body cells
–Each B-cell, T-cell, and antibody is
specific to what it attacks
B-Cells, Antibodies and T-cells are the
soldiers that fight infections if they get
past the wall…
Vaccinations
• Immune system exposed
to harmless version of pathogen
– stimulates B cell system to produce
antibodies to pathogen
• “active immunity”
– rapid response on future exposure
– creates immunity without getting disease!
• Most successful against viruses
Immune System Malfunctions
• Auto-immune diseases
– immune system attacks own molecules & cells
•
•
•
•
lupus
rheumatoid arthritis
diabetes
multiple sclerosis
• Allergies
– over-reaction to environmental antigens
• allergens = proteins on pollen, dust mites, in animal saliva
• stimulates release of histamine
CIRCULATORY SYSTEM RECAP
• Main Parts:
–Blood vessels
–Heart
–Red & White blood cells (includes B- and T-cells)
CIRCULATORY SYSTEM
• Main Functions:
–Transports antibodies & white blood
cells
–Transports toxins and waste products
to be removed
ALLERGIC REACTIONS are your body overreacting to
harmless substances.
DEBRIEF:
Quickwrite in Bellwork Journal:
Explain how all three systems
(Integumentary, Immune, and
Circulatory) work together for
defense in the body.
