Bloomâs Taxonomy. Bloomâs taxonomy is a classification system used to define and distinguish different levels of human cognitionâi.e., thinking, learning, and understanding.
Cardiac Muscle Tissue. Cardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body. In fact, cardiac muscle is only found in the heart and makes up the bulk of the heartâs mass. The heart beats powerfully and continuously throughout an entire lifetime without any rest, so cardiac muscle has evolved to have incredibly high contractile strength and endurance.
Cardiac muscle tissue is made up of many interlocking cardiac muscle cells, or fibers, that give the tissue its properties. Each cardiac muscle fiber contains a single nucleus and is striated, or striped, because it appears to have light and dark bands when seen through a microscope.
