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 levels.

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.

Which list is organized from simplest to most complex?

1. cell, organ system, organ, tissue2. cell, tissue, organ, organ system3. organ, organ system, cell, tissue4. tissue, organ, cell, organ system

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 What is BLOODBLOOD? How can we save lives ? How can we save lives through through BLOOD?BLOOD?

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.

Red Blood Cells

Kill Germs to Keep You Healthy!

White Blood Cells

Platelets

Clot to stop

bleeding.

The liquid portion of the blood.

Plasma

How can you share life with others

through BLOODBLOOD?

Donate!

Did you know that every 3

seconds someone needs

blood?

What is What is APHERESISAPHERESIS??

The collection of platelets

Did you know that platelets

only live 5 days outside your

body?

What is What is CORD BLOODCORD BLOOD??

Do you remember the last point of life?Do you remember the last point of life?

ORGAN AND TISSUEORGAN AND TISSUE

* The heart is an organ/muscle that pumps 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.

Veins – (blue)

Arteries – (red)

Heart

Circulatory System

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.

Brain Eyes

Nerves Spinal Cord

Nervous System* The brain is the control center for the

whole 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.

Digestive System

* What do you need to know about the digestive system?

• Esophagus:Esophagus: The tube food travels through from the mouth to the stomach.• Stomach:Stomach:Releases acid to break down food more so that the body can use the food’s

energy.• Small Intestine:Small Intestine: Absorbs the energy in food and gives it to the blood to carry to other body

parts.• Large Intestine:Large Intestine: Absorbs water from undigested food and pumps the waste out of the body.• Pancreas:Pancreas:Helps with food digestion and makes a chemical to digest sugar.• Gallbladder:Gallbladder:Stores and releases bile (a chemical that helps digest food) made by the liver.• Liver:Liver:Removes harmful substances from the bloodstream and helps with digestion.

Skull

Bone

Cartilage

Spinal Column

Joint

Muscle

Tendon

Muscular and

Skeletal System

* Bone, cartilage, tendons and ligaments can be donated and stored at tissue banks for future use.

* Kidneys – remove waste from the blood.

* Bladder – where urine is stored.* A kidney can be donated while we are

alive.

Excretory System

Hair

Nails

Skin

Integumentary System
