Transcript Organ Systems

The Organization of the
Human System
Homeostasis
 Homeostasis is
the regulation of
an organisms
internal, lifemaintaining
conditions despite
changes in the
environment.
Systems
 Systems are groups
of interacting
components that
perform a certain
function.
 Examples: Organ
System, Solar
System, and working
technological parts.
Matter
 Matter is anything
that takes up space
and has mass.
 Examples: Solids,
Liquids, and Gasses.
And pretty much
anything!!!
Atoms
 Atoms are the
smallest basic
particles of matter.
 Examples are
hydrogen atoms,
oxygen atoms, and
nitrogen atoms.
Molecules
 Molecules consist of
two or more atoms
put together.
 Examples: Water
(H20), Carbon
Dioxide (CO2), and
Methane (CH4).
Cells
 Cells are the
smallest basic unit of
life. Cells are the
building blocks of life.
 Examples:
Eukaryotic Cells and
Prokaryotic Cells
Tissues
 Tissue is a group of
cells working
together to perform a
specific function.
 Examples: Muscle
Tissue, Nervous
Tissue (brain, spinal
cord)
Organs
 Organ is two or more
tissues working
together to perform a
specific function in
the body.
 Examples: Heart,
Lungs, Brain,
Kidneys, Eye,
Stomach, Skin, and
Bones.
Organ Systems
 System: A group of
interacting
components that
perform a certain
function.
 Example to the left is
the Skeletal System
 Other Examples:
Circulatory System,
Digestive System,
Immune System,
Nervous System, and
Respiratory System.
Organisms
 Organism is an
individual living
system or creature.
 An organism maybe
unicellular or multicellular
 Examples:
Crocodiles, Frogs,
Plants, Bacteria,
Humans, Lizards
Which is the correct order
from smallest to largest?
 A. Tissue, Cell, Organ, Organ System,
Organism
 B. Cell, Tissue, Organ System, Organ,
Organism
 C. Cell, Tissue, Organ, Organ System,
Organism
 D. Cell, Organ, Tissue, Organ System,
Organism
Types of Tissues
 Epithelial Tissue:
Covers and protects
the underlying tissue.
 Example of this is
Skin
Types of Tissues
 Nervous Tissue
sends electrical
signals throughout
the body.
 Examples of nervous
tissue are your brain
tissue and spinal
cord tissue.
Types of Tissues
 Muscle Tissue is
made of cells that
contract and relax to
produce movement.
 Your Arms, Heart,
and Stomach have
muscle tissue
Types of Tissues
 Connective Tissue
helps join, supports,
protect, insulate,
nourish and cushion
organs.
Types of Tissues
Organs
 Organ is two or more
tissues working
together to perform a
specific function in
the body.
 Examples: Heart,
Lungs, Brain,
Kidneys, Eye,
Stomach, Skin, and
Bones.
Organ Systems
 System: A group of
interacting
components that
perform a certain
function.
 Example to the left is
the Skeletal System
 Other Examples:
Circulatory System,
Digestive System,
Immune System,
Nervous System, and
Respiratory System.
Organ Systems
 Integumentary
System protects
tissues and cells
beneath
 So what types of
tissues does the
integumentary
system primarily
composed of?
Organ Systems
 Muscular System
helps you move
 Made up primarily of
muscle tissues.
 Muscles are found
nearly every where
throughout your body.
 Any place you can
move or that naturally
moves inside your
body has muscle
Organ Systems
 Skeletal System
helps support and
protect body parts
 Have you ever
broken part of your
skeletal system?
 How did it feel?
 Does it take the
same amount of time
to heal as another
injury
Organ Systems
 Cardiovascular
System helps
circulate blood
throughout the body.
 Includes the heart,
veins, and arteries.
Organ Systems
 Respiratory Systems
helps absorb oxygen
and release carbon
dioxide.
 Perform the process
of respiration!
Organ Systems
 Urinary System
(Excretion System)
filters or removes
waste from your
body.
Organ Systems
 Male Reproductive
System produces
sperm needed for
reproduction.
Organ Systems
 Female Reproductive
System produces
eggs needed for
reproduction.
Organ Systems
 Nervous System
sends and receives
electrical signals
throughout the body.
Organ Systems
 Digestive System
breaks down food
into nutrients that the
body can absorb.
 The cells absorb this
nutrients by diffusion.
Organ Systems
 Lymphatic System
helps return leaked
fluids to blood and
gets rid of bacteria
and viruses.
Organ Systems
 Endocrine System
has glands that help
send out chemical
messages.
 Let’s you know when
your hungry, tired,
etc.
Organisms
 Organism is an
individual living
system or creature.
 An organism maybe
unicellular or multicellular
 Examples:
Crocodiles, Frogs,
Plants, Bacteria,
Humans, Lizards
What’s a System?
 A set of inter-related
components working
together to perform a
specific function is a
system.
 A function is a job of
a person or an
object.
Question #11
 Which of the following statements
describes how tissues, organs, and
organ systems are related?
 A. Organs form tissues, which form
organ systems.
 B. Organ Systems form organs, which
form tissues.
 C. Tissues form organs, which form
organ systems.
 D. None of the Above
Question #12
 The human skeleton has 206 bones.
The human skull has 22 bones. What
percentage of human bones are skull
bones?
 Skull Bones/Skeleton Bones=? Then
take that answer and multiply it by 100
 22/206 X 100/1 = 10.68%
Question #13
 How is the human body
and a car alike?
 Both the human body
and a car contain
several different
systems. A car has an
exhaust system to take
in air and remove waste
products. The human
body has a respiratory
system to take in air and
a digestive system to get
rid of waste products.
