Appendicular
Pectoral girdle &
upper limbs
Pelvic girdle & lower
limbs
Spaces within the body which house the
internal organs (viscera).
 Consists of two main cavities:

1. Dorsal cavity-the cavity along the back,
posterior side of the body
2. Ventral cavity-the cavity along the front,
anterior side of the body
Two major cavities within the axial portion:


Dorsal Cavity
Ventral Cavity

Cranial cavity (head)
Spinal/vertebral cavity

abdomen)

Orbital cavities (head)

Otic Cavities (head)
Thoracic cavity (thorax)
› Pericardial cavity
› Pleural cavities

Abdominopelvic cavity
(abdomen & pelvis)
› Abdominal cavity
› Pelvic cavity
Sheets of tissue that serve to protect body
structures.
Serous Membranes
› Double layered sheets of connective tissue separated
by a small amount of fluid
1. Parietal layer-outer layer, forms the outer boundary of
the cavity
2. Visceral layer-inner layer, sits directly on the organ it
covers
›
Serous fluid-secreted from the membrane to separate
the parietal & visceral layers.
Peritoneal Membranes
 Covers the stomach, liver, spleen,
gallbladder, small & large intestine in the
abdominal cavity.
 Covers the distal end of the large
intestine, bladder & internal reproductive
organs in the pelvic cavity.

Body Systems consist
of a collection of
organs that work
together to perform
a specific task or
function.
