•MUSCLE TISSUE

•NERVOUS TISSUE

• CONNECTIVE TISSUE

• EPITHELIAL TISSUE

•ORGAN

•ORGAN SYSTEM

CELLS• CELLS HAVE STRUCTURE

• CELL MEMBRANE-OUTER BORDER OF CELL

• NUCLEUS-DIRECTS CELL’S ACTIVITIES

• CYTOPLASM- CLEAR JELLY LIKE SUBSTANCE THAT CONTAINS MANY CELL STRUCTURES

• CELLS HAVE FUNCTION

• CELLS CARRY ON THE PROCESSES THAT KEEP ORGANISMS ALIVE.

• CELLS GROW, REPRODUCE, AND GET RID OF THE WASTE PRODUCTS.

A BASIC UNIT OF STRUCTURE AND

FUNCTION IN A LIVING THING

TISSUEGROUP OF SIMILAR CELLS THAT PERFORM THE SAME FUNCTION

MUSCLE TISSUECAN CONTRACT, OR

SHORTEN WHICH MAKES PARTS OF YOUR BODY

MOVE

NERVOUS TISSUEDIRECTS AND CONTROLS THE PROCESSES OF ALL

OTHER TISSUES BY CARRYING MESSAGES

BACK AND FORTH BETWEEN BRAIN AND OTHER PARTS OF THE

BODY

CONNECTIVE TISSUE

PROVIDES SUPPORT FOR YOUR BODY AND

CONNECTS ALL ITS PARTS. EXAMPLES ARE BONE

TISSUE AND FAT TISSUE

EPITHELIAL TISSUE

COVERS THE SURFACES OF YOUR BODY, INSIDE AND OUT.

SKIN, LINING OF YOUR ORGANS

ORGANSORGAN IS A STRUCTURE MADE UP OF DIFFERENT KINDS OF TISSUE

THAT PERFORMS A SPECIFIC JOB. THE JOB IS MORE COMPLEX THAN THAT OF A TISSUE. FOR EXAMPLE

THE HEART IS AN ORGAN MAKE UP OF MUSCLE, CONNECTIVE AND EPITHELIAL TISSUE. EACH TISSUE

CONTRIBUTES DIFFERENTLY TO THE ORGAN’S JOB.

WORKING TOGETHER TO ENABLE THE

PERFORMER TO DO THIS FEAT?
