Body Systems How is your body like a machine? Slide 2 Lets think
back. Why do all the body systems work together? Slide 3 To
maintain homeostasis! Slide 4 SKELETAL SYSTEM What are the
functions? - produces red and white blood cells -movement What
other systems are involved? -structural support -provide minerals -
muscular -immune Slide 5 MUSCULAR SYSTEM What other systems does it
involve? What are the functions? -movement (body parts, digestion,
circulation) -Skeletal -Digestive -Circulatory -Nervous Slide 6
Muscle Types SKELETALSMOOTHCARDIAC Slide 7 How do you bend your
elbow? The bicep muscle contracts, causing the elbow to bend. The
tricep muscle contracts, causing the elbow to straighten. This
works similar to what simple machine? To what are muscles attached?
Slide 8 LYMPHATIC SYSTEM What are the functions? protect body from
disease contains white blood cells, antibodies and lymph Slide 9
INTEGUMENTARY SYSTEM FunctionSystem Protection/Barrier Immune
Protect Against Dehydration Excretory Cutaneous SensationNervous
Regulate Body TempExcretory Excrete Sweat, Gases Excretory Slide 10
Integumentary Slide 11 How does skin vary in different organisms?
Slide 12 NERVOUS SYSTEM What are the functions? Respond to internal
and external stimuli How does the nervous system work? What other
systems are involved? all Slide 13 The Brain Hypothalamus Brain
Stem Cerebrum Cerebellum Medulla oblongata Slide 14 EXCRETORY What
are the functions? Detoxifies blood Urea, water, salts, excess
glucose, excess protein, CO 2 What other systems are involved?
Circulatory Endocrine Nervous Slide 15 Excretory Kidney Ureter
Bladder Urethra Blood Urine Slide 16 REPRODUCTIVE What are the
functions? produce gametes secondary sex characteristics produce
hormones What other systems are involved? Endocrine Slide 17
Reproductive Uterus Fallopian Tube Ovary Testes Penis Vagina Slide
18 ENDOCRINE What are the functions? -deliver chemical messages
through the body -produce hormones What other systems are involved?
nervous circulatory Slide 19 Endocrine Hypothalamus Thyroid Adrenal
Pituitary Pancreas Ovary Testes Slide 20 CIRCULATORY What are the
functions? -transport: -gases -fluids -waste products -nutrients
-hormones What other systems are involved? Excretory Respiratory
Endocrine Slide 21 Circulatory Heart Vein Aorta (Artery) Capillary
Slide 22 RESPIRATORY What are the functions? -exchange of carbon
dioxide and oxygen between the blood, air and tissues What other
systems are involved? Circulatory Slide 23 Respiratory Lungs
Diaphragm Alveoli Trachea Bronchi/ Bronchioles Where does gas
exchange take place? Slide 24 DIGESTIVE What are the functions? to
break down food into smaller particles with the help of enzymes so
it can be absorbed and used by cells. What other systems are
involved? Circulatory Nervous Slide 25 Digestive Mouth Liver
Stomach Small Intestine Large Intestine Rectum Esophagus Pancreas
Salivary Glands Slide 26 Digestive What substances help break down
the food that you eat? ENZYMES CompoundEnzymeMonomer Starch Lipids
Proteins Bile/Lipase Amylase Protease Monosaccharide Fatty Acids/
Glycerol Amino Acids Slide 27 Digestive Follow the path of food
during digestion. Where is food mechanically digested? Chemically
digested? Slide 28 What do we call the maintenance of an internal
environment? Homeostasis Slide 29 4 Major Themes in Maintaining
Balance These 4 major themes are interrelated to help your body
maintain homeostasis: Feedback loops Structure and function
Division of labor Interdependence of organ systems Slide 30
Feedback Loops Thermostat shuts off heater Room temperature falls
Thermostat activates heater Warm air is produced Room temperature
rises Thermostat feedback loop Slide 31 Feedback Loops What happens
to your body when you run outside in 100 o temperature? Slide 32
Feedback Loops How does this happen? Blood vessels in skin dilate
Sensors in the brain and skin detect a change in body temperature
Sweat glands release more sweat Body temperature regulates stimulus
response This is a stimulus-response Hormone message sent Slide 33
Feedback Loops So.What are some of the things that feedback
regulates? Feedback systems regulate: Blood sugar (glucose) Salt
content in blood Hormone production Blood pressure Ion content in
blood Water content in blood Slide 34 Structure and Function How is
the structure of your thumb related to its function? Slide 35
Structure and Function TRY THIS! Put a rubber band around your hand
so that the thumb cannot be used. Pick up your textbook and hand it
to the student next to you. Now - pick up a penny without going to
the edge of the desk or putting the penny up against something.
Slide 36 Structure and Function What is the function of plant
leaves? Why are these leaves shaped differently? Maple leaf Conifer
Cactus Slide 37 Structure and Function The dolphin and the fish are
unrelated organisms. Why do they have similar structures? Mammal -
dolphin Fish Queen snapper Slide 38 Division of Labor How many
people does it take to build a building? Slide 39 Division of Labor
You would need: Architect Construction workers Foreman Plumbers
Electricians Painters Why do you need all of these people? Slide 40
Division of Labor Why do you need so many different parts to digest
your food? Slide 41 Division of Labor Your body systems are divided
into different parts. Each part has its own special function. This
is called a Division of Labor. Slide 42 Interdependence of Body
Systems All the body systems work together to maintain
homeostasis.
