TISSUES AND
MEMBRANES
TISSUES
• 4 Main types of tissues:
– Epithelial tissue protects the body by
covering internal and external
surfaces
– Connective tissue supports and
connects organs and tissue

TISSUES
– Muscle tissue contains cell material
which has the ability to move the
body
– Nervous tissue contains cells that
react to stimuli and conduct an
impulse

MEMBRANES
• Epithelial membranes are classified
according to secretions produced:
– Mucous membranes
– Serous membranes
• Connective tissues support and
connect the organs and tissues

• Organs are groups of tissues joined
together to perform a single
function
• An organ system is a group of
organs that together perform a
specific function

DEGREE OF TISSUE REPAIR
• Damaged tissues are repaired
continually
• Depending on the type and location
of injury, some tissues are repaired
quickly

PROCESS OF EPITHELIAL
TISSUE REPAIR
• There are two types of epithelial
tissue repair:
– Primary repair involves skin where
there is no infection present
– Secondary repair occurs in large, open
wounds with tissue loss
