Animal Tissues

                The second activity that we did is about Animal Tissues. Tissues refer to the third level of organization of the body. It covers the surface areas. Tissues can be classified into different categories. The Epithelial Tissue, Connective Tissue, Muscular Tissue, Nervous Tissue and Reproductive Tissue.

                Epithelial tissues act as a protective covering. They also reduce friction between parts or organs of the body. Some of its functions are absorption, synthesis and secretion of various proteins, excretion, sensation and thermoregulation. There are also many classifications of epithelial tissues that differ in their shape and location.

                Connective Tissues are the most abundant of all the primary tissues. The functions of connective tissues are they are mechanical and protective, transport of nutrients, metabolites and signalling factors, storage of energy-rich lipids, water, and electrolytes and others. They are also classified in different types.

                Muscle Tissue has the ability to contract. There are three types of muscle tissues. These are skeletal, cardiac and smooth muscles. The functions of the muscle tissue depends on their type.

                Nervous Tissues control and coordinate body activities. They make up the major parts of the nervous system.

                Reproductive Tissues consists of ovaries and testes. They are responsible for the production of egg cells or sperm cells.

                In our activity, we observed the cells of the different specimens in each stations. We were asked to draw and label the type of tissue that we observed.
