Survey It: Form Questions Before you read the module, survey it and form at least two questions for yourself. When you have finished reading the module, return to these questions and answer them. Question 1: What is regeneration? Answer: Regeneration is when damaged or dead cells are replaced with cells of the same type (page 154.) Question 2: What is fibrosis? Answer: Fibrosis is when fibroblasts divide by mitosis and produce collagen to fill in the defect left by the injury, and the tissue does not regain its ability to function normally (page 154.) Key Concept: Why can fibrosis lead to a loss of function in an organ? Fibrosis is the formation of excessive connective tissue, causing scarring and failure of bodily organs and the skin. It is a very common cause of cardiovascular and renal disease, where excessive connective tissue destroys the structure and function of the organ with scar tissue. Build Your Own Summary Table: Tissues Now that you have reached the end of the chapter, you can build your own summary table of all the tissue types by filling in the below template. You have been given enough space to draw in examples of the tissue types, and doing so will really help you understand and remember their key components. Summary of Tissues Type of Tissue Structure Function(s) Location(s) Heals by Fibrosis or Regeneratio n? Epithelial tissue Simple squamous epithelium -Provides a barrier through which gases and fluids can be exchanged -Process serous fluids -Air sacs of lungs -Inner lining of ventral body cavities and blood vessels. -Certain parts of kidney Regeneration Simple cuboidal epithelium -Absorption -Secretion of mucus and other substances -Kidney tubules -Lower respiratory passages -Thyroid, salivary and mammary glands Regeneration
