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.
