Definition
Animal tissue refers to the different types of tissues found in animals, including humans. These tissues are groups of cells that perform specific functions. Think of it as different building blocks that construct various organs and systems. There are four main types: epithelial, connective, muscle, and nervous tissue. Each has a unique structure and role, from protecting surfaces to enabling movement. Animal tissue is essential for all bodily functions, like breathing, digesting, and thinking. It’s like understanding the components of a complex machine.
