Epithelial Tissue protects the body by covering
internal and external surfaces, and produces
secretions
 Skin
 covers the outside of the body
 lines the inside of the body
 Membrane
 two thin layers of tissue that join together
 cells may secrete a fluid

 formed by putting two thin
layers of tissue together,
cells may secrete a fluid
 Membranes are
vital because they separate
the cell from the outside
world. They also separate
compartments inside the
cell to protect important
processes and events.
MUCOUS MEMBRANES– lines
digestive, respiratory,
reproductive and urinary
systems – produces mucous to
lubricate and protect the lining
 They line various body cavities
that are exposed to the external
environment and internal
organs.
 Serous– double-walled
membrane - produces a
watery fluid (Serous
fluid) lines closed body
cavities
 the outer part of the
membrane that lines the
cavity is the PARIETAL
membrane
 the part that covers the
organs is the VISCERAL
membrane.
 Pleural, Pericardial,
Peritoneal
PLEURAL MEMBRANE – lines thoracic or chest cavity and protects the lungs
PERICARDIAL MEMBRANE – lines the heart cavity and protects the heart
PERITONEAL MEMBRANE – lines the abdominal cavity and protects abdominal organs
 Are made of two layers
of connective tissue.
Synovial membraneLines the joint cavity
and prevents friction in
joints.
Connective tissue supports and connects
organs and tissue
 Adipose type of connective tissue that stores fat cells
 Cartilage firm, flexible support of the embryonic skeleton
and part of the adult skeleton
 Tendons white bands of connective tissue attaching
skeletal muscle to bone
 Ligaments strong, flexible bands of connective tissue that
hold bones firmly together at the joints

 – supports and connects
organs and tissue
 These tissues are
responsible for cushioning,
supporting and
maintaining form within
the body and include
adipose, cartilage, bone,
tendons and ligaments
 Vascular
 LIGAMENTS – strong, flexible bands of connective

CARTILAGE – firm, flexible support of the

BONE- skeleton. Supports tissues and organs.

 Repair of damaged tissue occurs continually.
 Two types
Primary takes place in clean wound where
infection is not present.
Secondary larger and deeper wounds.

Muscle tissue contracts and moves a body
part
 Cardiac
 striated, involuntary
 contracts the heart
 Skeletal
 striated, voluntary
 attached to the skeleton
 Smooth
 nonstriated, involuntary
 provides movement in various body systems

 Nervous tissue reacts to stimulation and
conducts an impulse
1.01 Remember structural organization
18
 – cells that react to stimuli
and conduct an impulse
 Neurons are highly
specialized cells that
generate and transmit
electrical impulses (action
potentials) permitting
rapid communication
between distant areas of
the body.
