Final answer:
According to the Canadian Model of Occupational Performance, a person is made up of affective, cognitive, physical, and spiritual components that maintain health and well-being. Cells form the basic unit of life, tissues, organs, and organ systems, with DNA providing the genetic instructions for the body.
Step-by-step explanation:
The Canadian Model of Occupational Performance (CMOP) outlines that a person is made up of affective, cognitive, physical and spiritual components. These parts work together to maintain an individual's health and well-being, ensuring that each component functions properly in correlation with the others. This is crucial for person's occupational performance, which is a key focus of the CMOP.
When discussing the material composition of humans, we can note that cells are the basic unit of life and form the foundation of the human body. Various cells come together to form tissues, organs and eventually, entire organ systems that construct the complete organism. Furthermore, DNA, with its nucleotide bases, provides the essential genetic code required to build and maintain the body throughout one's lifespan.
