31.Epithelial tissuecovers body surfaces and lines hollow organs, body cavitiesand ducts ; it also forms glands . This tissue allows the body to interact with bothits internal and external environments.2.Connective Tissueprotects and supports the body and its organs. Various typesof connective tissues bind organs together, store energy reserves as fat, and helpprovide the body with immunity to disease-causing organisms3.Muscular tissueis composedof cells specializedfor contraction andgeneration of force. In the process, muscular tissue generates heat that warms thebody.4.Nervous tissuedetectschanges in a variety of conditionsinside and outside thebody and responds by generating electrical signals called nerve action potentials(nerve impulses) that activate muscular contractions and glandular secretions.Epithelial tissue and most types of connective tissue, except cartilage , bone , andblood, are more general in nature and have a wide distribution in the bodyThesetissues are components of most bodyorgans and have a wide range of structures andfunctions .Activity 1Directions : Identify the following tissue types and write its characteristics on theline below .1.Type of tissue :______________________Characteristics:____________________________________________________________________________________________________________________________________
