No, the organ is not the highest level of organization in the human body. The organ systems, which are made up of multiple organs working together, represent the highest level of organization in the human body. Examples of organ systems include the nervous system, respiratory system, and digestive system.
organism describes the entire individual, a human, just like it would describe a fish. However, "in" the human body, one would find SYSTEMS such as the digestive and nervous systems.
The levels of organization in the human body in descending order are: organism level (whole human body), organ systems level (such as the cardiovascular system), organ level (heart), tissue level (cardiac muscle tissue), cellular level (cardiac muscle cell), and molecular level (molecules within the cell).

The lowest level is the cell.
organ
The autonomic nervous system does. It works at the level of the spinal cord.
The fourth level of cell organization is an organ system. The levels of organization are: Cell, Tissue, Organ, Organ system.
Chemical Level(atoms, molecules), Cellular Level(smooth muscle cell), Tissue Level(smooth muscle tissue), Organ Level(stomach), System Level(digestive system), and Organism Level.
The function of the liver is digestive; it does the next level of processing of food, after it has been digested by the alimentary canal.
Circulatory system
The organ system level is the fourth and highest level of organization in a multicellular organism. At this level, multiple organs work together to carry out specific functions, such as the circulatory system or digestive system.
