Name________________________________ Date__________ Period_____ I’m Bigger Than You An organ, such as the heart, is made up of groups of tissues that work together to perform a specific function. The heart is a pump that keeps blood flowing throughout the body. The heart is primarily made up of muscle tissue, but also contains connective and nerve tissue. However, each of these individual types of tissues has its own primary function, which differs from the basic function of the heart. Without the assistance of the cells in different organs, an entire organism is unable to stay alive. In a similar manner, cells rely on different organs of the organism doing their jobs to keep these cells alive. You just finished learning about what the levels of organization are: Cells Tissues Organs Organ Systems Organism Now it’s your turn.
