Complex tissues are mainly concerned with the transportation of mineral nutrients, organic solutes (food materials), and water. That's why it is also known as conducting and vascular tissue.
Tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material. By definition, tissues are absent from unicellular organisms. Learn more about tissues in this article.
Tissues are organized into four broad categories based on structural and functional similarities. These categories are epithelial, connective, muscle, and nervous. The primary tissue types work together to contribute to the overall health and maintenance of the human body.
Master the concept of tissues – explore their definition, major types (epithelial, connective, muscular, nervous), and practical examples with easy-to-follow explanations and diagrams.
Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is characterized by specific functions that contribute to the overall health and maintenance of the body.:background_color(FFFFFF):format(jpeg)/images/article/en/introduction-to-tissues-epithelial-connective-muscle-and-nervous-tissue/3Py3TunS4W4sBpH989aqA_2OkPuT9BljkRpCYhgUaA_Epithelial_cell_nuclei02.png){kind=logo}
Overview of the main cellular components and tissues. A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
