Let’s talk a little about our
bodies.
Are we made up of cells?
Yes, cells are the basic structural unit of a living thing.
Are we unicellular organisms (made
up of one cell) or multicellular
organisms (made up of more than one
cell)?
We are multicellular organisms.
Cells in multicellular organisms are organized at different

Let’s talk a little about our
bodies.
First, they are organized into
tissues.
What is a tissue?
- A large group of similar cells that work together to perform a
specific function.
- Example: Muscle cells form muscle tissue, nerve cells form
nerve tissue, bone cells form bone tissue, skin cells form skin
tissue, etc.
What is an organ?
-
A group of related tissues that perform a specific function.
Example: The heart, brain, stomach, liver, etc.

Let’s talk a little about our
bodies.
Cells, Tissues, Organs,
what is next?
• Organ Systems
– A group of related organs that work together to perform a
specific function.
– Can you name one organ system?
• All this makes up an organism – YOU!
– Organ systems combine to form the entire organism.
– Most multicellular organisms have several organ
systems.

What happens if one organ, tissue or cell in
one of the organ systems stops working?
You get sick. . .
The Five Points of Life raises
awareness for the five ways to
share life with others through
the donation of:
1. Blood
2. Apheresis
3. Marrow
4. Cord Blood
5. Organ and Tissue
What is BLOOD? How can we save lives
through BLOOD?
Red Blood Cells
Act like a boat by picking up oxygen in
the lungs, dropping it off to other body
parts and then carrying away carbon
dioxide we breathe out from our lungs.

White Blood Cells
Kill Germs to Keep You
Healthy!
Platelets
Clot to
stop
bleeding.
Plasma
The liquid portion of the
blood.
How can you share life with others
through BLOOD?
Donate!
Did you know that
every 3 seconds
someone needs
blood?
What is APHERESIS?
The collection of
platelets
Did you know that
platelets
only live 5 days
outside your
body?
What is CORD BLOOD?
Do you remember the last point of life?
ORGAN AND TISSUE
Circulatory
* The heart is an organ/muscle that pumps
System
blood all over the body and is part of the
circulatory system. The circulatory system is
in charge of getting the blood around the
body.
Heart
Arteries – (red)
Veins – (blue)
Respiratory System
*Lungs – pair of organs that put oxygen in the body.
*Trachea – air travels through this organ from the
mouth to the lungs.
*The respiratory system is in charge of the gas
exchange between the blood and the
environment.
Nervous
* The brain is the control center for the whole
System
body and the brain, eyes and spinal cord are
located in the nervous system. The nervous
system is in charge of all functions of the
body.
Brain
Eyes
Nerves
Spinal Cord
Digestive
System
* What do you need to know about
the
digestive system?
•
Esophagus:
The tube food travels through from the mouth to the stomach.
•
Stomach:
Releases acid to break down food more so that the body can use the food’s
energy.
•
Small Intestine:
Absorbs the energy in food and gives it to the blood to carry to other body parts.
•
Large Intestine:
Absorbs water from undigested food and pumps the waste out of the body.
•
Pancreas:
Helps with food digestion and makes a chemical to digest sugar.
•
Gallbladder:
Stores and releases bile (a chemical that helps digest food) made by the liver.
•
Liver:
Removes harmful substances from the bloodstream and helps with digestion.
* Bone, cartilage, tendons and ligaments can be
donated and stored at tissue banks for future
use.
Skull
Bone
Muscle
Cartilage
Spinal
Column
Joint
Tendon
Muscular
and
Skeletal
System
Excretory System
* Kidneys – remove waste from the blood.
* Bladder – where urine is stored.
* A kidney can be donated while we are alive.

Activity Time!
1.
Are we unicellular or multicellular organisms?
– Multicellular
2.
This is the first point of life.
– Blood
3.
What are the four components of blood?
– Red Blood Cells, White Blood Cells, Platelets and
Plasma
4.
What part of blood carries oxygen around the body?
– Red Blood Cells
5.
What component makes our blood red?
– Red Blood Cells
6.
What is the collection of platelets (or second part of life)
called?
– Apheresis
7.
What do platelets do?
– Clot
8.
What is the liquid part of our blood?
9.
Where does cord blood come from?
– The Umbilical Cord
10.
Who gives permission to donate cord blood?
– The Mommy
11.
What is the last point of life?
– Organ and Tissue
12.
Name 2 out of the 6 organs that are currently transplanted?
– Kidneys, Heart, Lungs, Liver, Pancreas and Intestines
13.
What organ can regenerate itself?
– The Liver
14.
What organ is usually commonly given as a “live donation?”
– Kidneys
15.
Can bone, veins and skin be donated?
– Yes!
16.
Do you know someone that has received or donated an
organ?
– Freebee!
17.
Name the main organ part of the circulatory system.
– The Heart
