Form and Function Flashcards
(44 cards)
Anatomy
the study of biological form of an organism
Physiology
the study of the biological functions an organism performs
Interstitial fluid
the fluid between cells
allows for the movement of material into and out of cells
2 main body cavities
Dorsal body cavity and ventral body cavity
dorsal body cavity
forms within skull and vertebrae
ventral body cavity
bounded by the rib cage and vertebral column
Ventral cavity is divided into
thoracic cavity and abdominopelvic cavity
thoracic cavity
pericardial cavity
pleural cavity
abdominal pelvic cavity
most organs
peritoneal cavity - coelomic space
Pericardial cavity
around the heart
pleural cavity
around the lungs
Four main categories of tissues
epithelial, connective, muscle, and nervous
Epithelial tissue
covers the outside of the body and lines the organs and cavities within the body
shape of epithelial cells may be
cuboidal, columnar, or squamous
arrangement of epithelial cells may be
simple, stratified, or pseudostratified
Connective tissues
derive from embryonic mesoderm
Two classes of connective tissues
connective tissue proper - loose or dense
special connective tissue - cartilage, bone, and blood
Connective tissue proper
fibroblasts produce and secrete extracellular matrix
loose connective tissue
cells scattered within a matrix that contains a large amount of ground substance
collagen
loose tissue
supports tissue
Elastin
makes tissue elastic
Reticulin
helps support network of collagen
Cells in connective tissue
fibroblasts and macrophages
fibroblasts
secrete the protein of extracellular fibers
