Document Summary
42 the animal body & principles of regulation: organization of the vertebrate body. Four levels of organization (cell, tissues, organ, organ system. Humans have 210 different types of cells: tissues. Groups of cells that are similar in structure and function and are organized together. 3 fundamental embryonic tissues: endoderm, mesoderm, and ectoderm. In adult vertebrates there 4 primary/principle tissues: epithelial, connective, muscle, and nerve tissue: organs. Body structures composed of many diff type tissue that form a structural and functional unit. Ex: heart contains cardiac muscle tissue, connective tissue, and epithelial tissue: organ system. Group of organs that cooperate to perform major body activities. Ex: circulatory system is composed of the heart and blood vessels. These organs cooperate in the transport of blood through the body. Vertebrate body has 11 principle organ systems: general body plan of vertebrates. Body plan is a tube within a tube. Outer tube: main vertebrate body (supported by internal skeleton)
