Describe the various levels of animal organization. 2. Know  the characteristics of the four main  tissues, noting  their structure, function, and  examples   of each. 3. Know  the types of cells that  compose  each tissue  type, and  cite examples of organs  that  contain  significant amounts  of each tissue type. 4. Characterize each of the major organ systems of the human  body. 5. Describe how  the four principal tissue types are organized  into an organ such as the skin.

stem cells stratified epithelium tight junctions urinary  system Lecture Outline Impacts, Issues: Open  or Close the Stem Cell Factories? A. Stem cells form when  a zygote first begins to divide. 1. Stem cells can divide indefinitely without  differentiating.  2. They can be coaxed into forming many  cell types. B. The most pliable of stem cells comes from human  embryos. 1. These cells may be able to repair damaged  nervous  tissue. 2. But ethical issues have been raised  because of the source of the tissue. C. The cells of the body are organized  into levels. 1. A tissue is a group  of cells that performs a common  task. 2.
