Cardiac Tissue Function
Cardiac Tissue Function: Cardiac tissue, found only in the heart, contracts rhythmically and involuntarily to pump blood throughout the body, powered by electrical impulses.
Cardiac Muscle Fibers
Cardiac Muscle Fibers: Cardiac muscle fibers are striated, branched cells found only in the heart; they contract rhythmically and are connected by intercalated discs for synchronized heartbeats.
Cardiac Muscle Cell
Cardiac Muscle Cell: A cardiac muscle cell, or cardiomyocyte, is a specialized muscle fiber found only in the heart, characterized by striations and intercalated discs that facilitate synchronized contractions.
Cardiac Cells
Cardiac Cells: Cardiac cells, or cardiomyocytes, are specialized muscle cells that make up the heart and are responsible for heart contraction.
Cardiac And Pyloric Sphincter
Cardiac And Pyloric Sphincter: The cardiac sphincter is a muscle located between the esophagus and stomach, preventing acid reflux. The pyloric sphincter controls the flow of partially digested food from the stomach into the small intestine, regulating digestion.
