1. TISSUES!

2. OBJECTIVES  Students will learn about the four different types of tissues that make up organs.

3. Epithelial Tissue  Epithelial tissue is used for protection, secretion, absorption and filtration.  It protects the body from dirt, dust and bacteria.  The skin is primarily made of Epithelial tissue!

4. Connective Tissue  The body consists mostly of connective tissues.  Connective tissues protect and support the body.  Connective tissues are found in cartilage, bones, blood and lymph.

5. Muscle Tissue  There are three types of muscle tissues: skeletal, smooth and cardiac.  Skeletal is used in the contraction of skeletal parts (voluntary). An example is when you move your hands and arms.  Smooth is found in blood vessels and internal organs (involuntary).  Cardiac is found in the heart (involuntary). An example could be heartbeat.
