1. Tissues, Organs & Systems

2. Tissues
A group of specialized cells that have the same structure and function.

3. Four Types of Tissues Type Function Example Epithelial Connective
line organ surfaces
skin
organ walls
etc.
Connective
hold everything together
Tendons
cartilage
- etc.
Muscle
contract and change sizes
muscles
organs
blood vessels
Nervous
Senses stimuli and transmits signals
brain
spinal cord
nerves
- etc

5. Organs
Different tissues types grouped together to perform a specific function.
Ex. - Artery
- Skin
- Liver
- Pancreas
- Etc.
Artery
Tissue

6. Systems A group of organs that perform a common task.
Ex. The digestive system consists of many organs throughout the body which transform food into nutrients for the body. Then the excess is discarded.

7. System Function 1 Digestive 2 Respiratory 3 Circulatory 4 Lymphatic
Transforms food into nutrients the body can use. 2
Respiratory
Provides the body with oxygen while eliminating carbon dioxide. 3
Circulatory
Fluids transport nutrients throughout the body and carry toxins toward the liver and lungs. 4
Lymphatic
Drain liquids from tissues, placing it back into the bloodstream.
Removes cell debris and harmful bacteria

8. System Function 5 6 7 8 Excretory Nervous Musculoskeletal Reproductive
Balances the liquids in the body.
Removes urea waste (urea is found in foods containing protein) 6
Nervous
Systems control
Thinking and Memory 7
Musculoskeletal
Body movement
Protects and holds organs in place 8
Reproductive
Gamete production (sperm and egg)
