Organization and Systems
Organization

Organization refers to a structure that
allows easy management of related, or
otherwise connected, items.
Consider Our Country

With over 300 million people living in the
United States, how do we manage to
keep order?
Consider Our Country

Our country is organized:
 Four regions
 50 States
 Over 3,000 counties
 Over 35,000 cities and towns
 Over 300 million people
Consider Our Country

Our country is organized:
 We are one country, with one
government, and one law of the
land (Constitution).
 We are broken into regions and
states where there are local laws
to enforce the Constitution.
 We are further broken into
counties and cities to enforce the
local laws of the state.
 Each person is responsible for
governing his/her own action
according to all the laws.
Consider Your Trash

You produce about 5 Ibs of trash a day!
 35 Ibs a week!
 155 Ibs a month!
 1,825 Ibs a year!
For a house with five people, that adds
up to 9,125 Ibs each year!
 How about everyone in your
neighborhood and city?

Consider Your Trash

Discussion:
Where does all the trash go?
How is your city organized to dispose of
all its trash?
Consider Your Body

Your body is also organized in an
effective way to fulfill all of its life
processes!
Consider Your Body

There are over 30 trillion cells in your
body.
 Different sizes
 Different shapes
 Different functions
 Similar purpose: to maintain life
Consider Your Body

Cells- the basic building blocks of the
body
Consider Your Body

Tissue- a group of similar cells working
together
Consider Your Body

Organ- a group of similar tissues
working together to perform a task
Consider Your Body

Organ System- a group of organs
working together
Consider Your Body

Body- a group of organ systems working
together to maintain life
Consider Your Body

The organization of the Human Body
Four Types of Tissues
Epithelial
• Covers all body surfaces
• Ex. Skin and lining of intestines
Muscular
• Causes body parts to move due to contractions
• Ex. Muscles in the heart, arms, and stomach
Nervous
Connective
• Carries electrical messages through body to sense
changes in the environment
• Ex. Brain, spinal cord, and nerves
• Bind structures together, provides support and
protection
• Ex. Bones, fats, and blood
Genesis 2:7
“And the Lord God formed man of the dust
of the ground, and breathed into his
nostrils the breath of life; and man
became a living being.” KJV
God Himself took the time to make us the
way we are. He formed our bodies with
all its parts. He designed them to meet
all the needs of a living organism.
Psalm 139:13-14
Paraphrased
You formed my inward parts. You weaved
me in my mother’s womb. I will praise you
because I am fearfully and wonderfully
made. Wonderful are Your works.
Systems of The Human Body
1. Circulatory
2. Respiratory
3. Skeletal
4. Muscular
5. Digestive
6. Excretory
7. Integumentary (Skin)
8. Endocrine
9. Nervous
10. Immune
11. Reproductive
Circulatory System
Your body’s transport system defined as
the group of body parts that transports
the blood throughout the body.
Circulatory System

Functions:
 Transport fuel to the body
 Transport waste to liver and kidney
 Transport cells to fight disease
 Transport hormones throughout body
Circulatory System

Organs:
 Heart
○ Pumps blood to body
 Arteries
○ Carries blood away from the heart
 Veins
○ Carries blood back to the heart
 Capillaries
○ Carries blood from arteries to cells to veins
○ Nutrients, gases, and wastes are exchanged
between blood and tissues
Respiratory System
The group of passages that
exchange gases.
Respiratory System

Functions:
 To carry oxygen to the blood
 To carry carbon dioxide out of the body
Respiratory System

Organs:
 Lungs
 Nose
 Mouth
 Pharynx
 Trachea
 Bronchi
 Alveoli
 Diaphragm
Skeletal System
The combination of your joints and
connective tissues.
Skeletal System

Functions:
 To provide support and protection
 Allows for movement
Skeletal System

Organs and Tissues:
 Bones
 Ligaments
 Joints
 Cartilage
Muscular System
The groups of tissues that make your
body parts move.
Muscular System

Functions:
 Provides support and protection
 Allows for movement
Muscular System

Organs and Tissues:
 Smooth Muscle (Stomach wall)
 Skeletal Muscle (Arms, Legs, etc.)
 Cardiac Muscle (Heart)
Digestive System
The organs that take in food and break it
down into chemical forms that can be
used by the body.
Digestive System

Functions:
 Digestion- the process in which food is
broken down
Digestive System

Organs:
 Mouth (teeth, tongue)
 Esophagus
 Stomach
 Small Intestine
 Large Intestine
Excretory System
The organs that excrete (get rid of) waste
from the body.
Excretory System

Organs and Functions:
 The Large Intestine: excretes undigested
food
 The Urinary Tract: excretes waste from
blood
 Lungs: expel carbon dioxide
