By looking at the processes that occur between cells, it seems as though humans are in fact comparable to machines. Organelles within each cell work like machine by repeating task upon task and doing their role in the cell as a whole, whether it be replicating DNA, making proteins, packaging vesicles, etc. Aggregates of cells replicate and form tissues, further organizing the cells and the machinery within the cell. This organization is specific, according to the coding of the cell’s DNA. With one more level of organization, these tissues form organs such as the heart, lungs, stomach, and brain, which carry out even further complex tasks such as circulation, respiration, digestion, and cognition. The human body encompasses all these machines as if it were a factory full of machines. But what is a factory without a manager or president? The best example I thought of was patient who is in a coma. Although the body’s machines still function, there is a lack of interaction between the patient and other humans or with the outside. This ability of humans to perceive, interact, learn, and explore the world around us is what ultimately distinguishes us from a machine.
