The cells of most animals interact at three levels of organization: tissues, organs, and organ systems 2. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. These maintain a physiological behavior and a shared embryonic origin. Epithelial Tissue & Connective Tissue : Animal Tissue It is a known fact to all biology enthusiasts that unlike unicellular microbes, animals and plants show a higher level of organization. Tissues are groups of cells that have a similar structure and act together to perform a specific function. Movement in the Human body is only . Fig. Connective tissue is defined as all the tissues originated from the mesoderm layer of the animal embryo. So no part of a plant-body is homologous with a part of animal-body. . Ciliary projections present in the nose or upper respiratory tract, trap the dust particles and prevent it from entering the body In multicellular animals, a group of similar cells along with intercellular stances perform a specific function. Tissue All cells are well organised and coordinated to work in a group. Their functions include protection, absorption, and secretion. Put simply, tissues are what organs are made of. Epithelial Tissues: These tissues are very closely packed and form a continuous protective layer over the surface of organs and inner lining of the body cavity. Now plants have a different mode of development than animals (plausibly due to evolution in separate route). Animal tissue is a type of tissue made up of one or more types of embryonic cells that perform the same functions in the animal body. Moreover, it binds skin and muscles and also provides support to internal organs. Tissues (Animal Anatomy and Physiology) STUDY. Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities.Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.The free surface of epithelial tissue is usually exposed to fluid or the air, while the . Animal tissues protect, secrete, and absorb and are separated from the other tissues below by a basal lamina. - A cell is a mass of protoplasm surrounded by a plasma membrane. The animal body comprises four basic types of tissues, all of which vary in their origin and function. Epithelial Tissue is one of the four types of tissue (epithelial, muscular, connective, and nervous) in animals which consists of closely aggregated polyhedral cells adhering firmly to one another, forming cellular sheets that line the interior of hollow organs and cover the body surface. Multicellular, complex animals have four primary types of tissue: epithelial, connective, muscle, and nervous.
