Tissues are groups of cells with a common structure (form) and function (job). There are four main tissues in the body – epithelium, muscle, connective tissue and nervous tissue.

Muscle Tissue Functions (jobs):

    • Responsible for body movement

    • Moves blood, food, waste through body’s organs

    • Responsible for mechanical digestion

 

The 3 Types of Muscle Tissue:

1) Smooth Muscle

    • found in organ walls and blood vessel walls

    • involuntary (works without our control)

    • spindle-shaped cells for pushing things along (blood, food, waste) through the body’s organs

 

2) Skeletal Muscle

    • make up large body muscles

    • voluntary (we control them)

    • striated muscle packed in bundles and attached to bones for movement

 

3) Cardiac Muscle 

    • found in heart wall

    • involuntary (works without our control)

    • striated muscle with intercalated discs connecting cells for synchronized contractions during heart beat
