TISSUES AND MEMBRANES
Tissues
cells that are grouped
because they are similar
in shape, size, structure,
and function
EPITHELIAL TISSUE
protects the body by covering
internal and external surfaces,
and produces secretions
CONNECTIVE TISSUE
supports and connects organs and
tissue
Types of Connective Tissue
• Adipose tissue (fat)
• Areolar (loose) tisue—surrounds
various organs
• Dense fibrous—Ligaments & tendons
• Bone tissue
• Cartilage
• Blood
• Lymph
More about Connective Tissue
• ADIPOSE TISSUE – type of connective
tissue that stores fat cells
• LIGAMENTS – strong, flexible bands of
connective tissue that hold bones firmly
together at the joints
• TENDONS – white bands of connective
tissue attaching skeletal muscle to bone
• CARTILAGE – firm, flexible support of the
embryonic skeleton and part of the adult
skeleton
MUSCLE TISSUE
Has the ability
to contract and
move the body
NERVOUS TISSUE
Cells that react to stimuli and conduct
an impulse
MEMBRANES
Formed by putting two
thin layers of tissue
together, cells may
secrete a fluid
MUCOUS MEMBRANES
Lines digestive, respiratory,
reproductive and urinary systems –
produces mucous to lubricate and
protect the lining
SEROUS MEMBRANES
Double-walled membrane – produces a
watery 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.
Parts of Serous Membrane
Types of Serous Membranes
• 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
ORGAN SYSTEM
a group of organs
which act together to
perform a specific,
related function
Integumentary
Skin and its appendages
Skeletal
Bones
Muscular
Different types of muscles in the body
Digestive
stomach, intestines & other organs
Respiratory
lungs and other structures for
breathing
Circulatory
Heart and blood vessels
Nervous
Brain, spinal cord, nerves
Urinary System
Rids body of waste in form of
urine
Endocrine
Glands that produce hormones
Reproductive
organs that allow for production
of offspring
