Levels of Structural Organization
TISSUES
Animal Tissues
Tissue• A collection of similar cells that
perform a specialized function• 4 major types:

Tissue Types

Epithelial Tissue• Thin sheets of tightly packed cells
lining organs• Example: skin, lining of capillaries
and digestive tract• Function:– Prevent dehydration– Reduce friction

Types of Epithelial Tissue
Connective Tissue• Function: structural support,
insulation• Example: bone, cartilage, fat, blood• Cells are held together by a liquid /
solid / gel matrix
Types of Connective Tissue

Muscle Tissue• Bundles of long cells• Capable of
shortening or contracting
• Function: movement• Examples: heart
muscles, skeletal muscles, intercostal muscles of the digestive tract

• Neurons that interact with each other• Conduct electrical impulses• Communicates within the body• Example: brain

ORGAN & ORGAN SYSTEM
Activity: OrganStep 1 – Label Organs
1. Draw shape of human body on chart paper2. Draw & Label as many ORGANS as possible inside the human body.
• Discuss within your group,-Where does each organ go within our body?-What is the main function of each organ?
3. Check your diagram to your teacher
Step 2 – Charades1.Silently act out the function of your assigned organ
*You can use analog to describe the function (ex. The Brain is the controlling center for all other organs, it will be the rule of principle in school community. Act out the rule of principle.)
2.Class will guess your organ with explanation
Activity: Organ System
Step 3 – Organ Systems1. On your human body diagram, connect organs
that are responsible for each of the organ system.
