TISSUES!

OBJECTIVES

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

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!

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.

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.

Nerve Tissue

Nerve tissues allow your body to receive stimuli and conduct impulses to and from all parts of the body.

A stimuli is anything that causes you to have a reaction.

An impulse is a strong desire to act a certain way.
