The document discusses the four main types of tissues in the human body: connective, epithelial, muscle, and nervous tissue. Each tissue is further divided into subcategories based on their structure and function. Connective tissues include bone, cartilage, blood, and fibrous and adipose tissues. Epithelial tissues are classified as simple or stratified based on their cell layers. Muscle tissues include skeletal, smooth and cardiac muscle. Nervous tissue consists of neurons that control bodily functions.
