Anatomy: study of the form of an organism’s structure
Physiology: study of the functions of those above structures
In a bear, single muscle cell. This cell’s main function is to CONTRACT, and the
stripes in the cells indicate the precise alignment of strands of proteins that
perform that function. Each muscle cell is also branched, providing for multiple
connections to other cells that ensure coordination of contractions of all the
muscle cells in the heart. Together, these heart cells make up a tissue = SECOND
Tissue: integrated group of similar cells that perform a common function. The cells of a tissue are specialized and
their structure enables them to perform a specific task; coordination contraction.
Organ: made up of two or more types of tissue that together perform a specific
task. Muscle tissue, the heart includes nervous, epithelial and connective tissue.
The circulatory system, an organ system that the heart is a component.
Organ system: consists of multiple organs that together perform a vital body
function. Other parts of the circulatory system include the blood and blood
vessels; arteries, veins and capillaries.
and all functioning together as an integrated, coordinated un
