1. Cells

2. Organs

3. Tissues

4. Systems

The correct answer is: Tissues

The term that describes living tissues with a similar structure and function is "tissues." Tissues are groups of cells that work together to perform specific tasks within the body. They are considered the building blocks of organs, which are made up of multiple types of tissues working in concert to carry out more complex functions. In the context of biological organization, tissues can be categorized into four main types: epithelial, connective, muscle, and nervous tissue. Each of these tissue types serves distinct purposes, such as protecting surfaces, supporting structures, enabling movement, and transmitting signals throughout the body. Understanding the definition of tissues is crucial in fields such as esthetics, where knowledge of skin layers and their functions is fundamental to effective treatments and products. Knowing how tissues interact and contribute to overall body function helps estheticians make informed recommendations for skin care and health.
