Detailed explanation-1: -Life is characterized by hierarchical levels of organization, each with emergent properties. In most animals, combinations of various tissues make up functional units called organs, and groups of organs work together as organ systems.
Detailed explanation-2: -A group of organs working together to perform a specific function is called an organ system. An example of an organ system is the circulatory system, which includes different organs like the heart, arteries, veins, and capillaries.
Detailed explanation-3: -Multicellular, complex animals have four primary types of tissue: epithelial, connective, muscle, and nervous. Recall that tissues are groups of similar cells carrying out related functions. These tissues combine to form organs-like the skin or kidney-that have specific, specialized functions within the body.
