Uniqueness
In the previous section, Units to Unity, the importance of each biological unit – be it cell, tissue, or organ – was described as a function of its joining with other units to form a larger whole. Given this description and the discussion of the ‘pride’ of the atom or cell it would seem that the individuality of each biological unit should be considered subordinate to its role in the group dynamic. However, it is important to understand that the unique characteristics of the individual unit are, in fact, critical to the proper functioning of the whole that they construct and must not be devalued. For instance, it is the great diversity of cellular structures and morphology in the body that allows for a vast array of tissues and organs, each with a distinct and critical physiologic function. Without the uniqueness of the individual cell such functional diversity would not be possible.

Respect of the Group for Individuality with Respect of the Individual for the Group |

The metallic poster hangs outside on the brick wall of Newton North High school in Newton Massachusetts. The uniqueness of the individual is key but on the other hand the individual has to respect the group. The bricks in the background are each individuals with different hues and colors built from the same mold. Together they form a strong wall which supports the building and which also in this case supports the the enormous poster. 86093pb02.800 brick wall outside Newton North High School Newton Mass respect individuality respect diversity respect the group units to unity Courtesy Ashley Davidoff MD Davidoff photography |

Like many other concepts introduced thus far, such as links and connections and units to unity, uniqueness applies not only to biology, but also to human populations and society at large. It is common knowledge, for example, that each person is the result of his/her unique genetic make-up and social experiences. In this way, every human being, like the woman pictured above, is unique and able to offer something different to his/her culture and society. It is here that we encounter the paradoxical relationship between the individual and the group that was discussed above with respect to biology: uniqueness and individuality actually have the capacity to strengthen the group dynamic rather than compromise it. Among humans this is largely reflected by the calls of civil rights activists to respect diversity, if not to fulfill the individual’s right to respect then to foster and maintain cohesive communities. Indeed, the words “united we stand, divided we fall” have often been used to inspire and motivate Americans to unite in spite of and in celebration of their differences. Thus, whether one is discussing cells, tissues, or people their uniqueness as units comprising a larger whole must be continually recognized and respected. The images below are arranged to convey just that.
The Cell

The Cell Each Different in their Own Kind, but Vastly Different from Others in Another Culture |

The cell is the building block of all biological structure. In this image a few polygonal cells of the liver are attached together. Each cell has a central dark nucleus which is embedded in a pinkish cytoplasm. The nucleus takes up approximately 1/5 to 1/6 of the volume of the cell.

The Tissue

Different Configuations for Different Tissues – And Differences in the Same Tissue |
|
The cells of the liver are organized in cords and plates and are organized like spokes of a wheel around the central vein. The plates and cords are lined by the sinusoids which are the channels which carry blood to the liver. Just below the sinusoids, between the wall of the sinusoid and the capsule of the liver there is a space called the space of Disse which carries the lymphatic fluid of the liver. (Image courtesy |

|
The sinusoids and hepatic cords combine to form a liver lobule which is a functional and structural unit of the liver. At the center of the lobule is the central vein from which emanate many cords of liver tissue. At the periphery of the lobule there are 4-5 groups of portal triads consisting of distal branches of the portal vein (dark blue), hepatic artery (red) and biliary radicle (green). They create the border of the lobule. Normal lung histology This image is a panoramic view of the lung showing secondary lobules and interlobular septa.

The lobules of the liver combine to form lobes. The liver has two lobes. In this anatomical specimen the right lobe is seen on the left side of the image lateral to the stone containing gallbladder, while the left lobe is seen with the branching portal triad surrounded by the whitened connective tissue. on the right side of the image.
