  5. What are some typical causes for localized or systemic edema?
    • -loss of serum albumin due to decr. synthesis in liver or glomerular injury
    • -lymphatic obstruction

  7. What potentially reversible response of tissue is due to lack of use?
  8. (T/F) The gut is lined with keratinized stratified squamous tissue.
  9. (T/F)) The innermost surfaces of blood vessels are lined with endothelial cells.
