Describe the primary criteria for evaluating tissue quality.

The primary criteria for evaluating tissue quality are contamination status, structural integrity, and cell viability.

Contamination status is crucial because any presence of pathogens or contaminants can compromise the safety and effectiveness of the tissue for transplantation. Ensuring that tissues are free from infectious agents is essential for protecting both the recipients and the healthcare environment.

Structural integrity refers to the physical condition of the tissue. This aspect involves assessing whether the tissue maintains its intended architecture, which is vital for its function after transplantation. A tissue's structural integrity affects how well it can integrate with the host's body and perform its intended role.

Cell viability indicates the health and functionality of the cells within the tissue. Viable cells are necessary for the tissue to fulfill its biological purpose, whether that involves growth, repair, or specific physiological functions once transplanted. Evaluating cell viability ensures that the tissue is capable of functioning as expected post-transplantation.

In contrast, other criteria such as size, weight, color, texture, and donor age may provide some information but do not fundamentally assess the tissue's quality concerning its biological and functional properties. Size and weight can influence the application of the tissue but do not directly correlate to its safety or effectiveness. Similarly, color and texture may aid in visual assessments but
