💡 Big idea: Every organ in the body is built from combinations of just four tissue types, and damage to those tissues tells the pathologist what went wrong.

  1. 0:00Quick-draw warm-up: sketch what you think a cell looks like; compare to actual cell diagrams
  2. 0:08Teacher-led notes: four tissue types, defining features of each, which organs they build

Mr. Mendoza's 5-minute intro
  • Everything in your body, every organ, every gland, every vessel, is made from combinations of just four tissue types. If you can identify the tissue, you can start to understand what organ it came from and what might have gone wrong with it.
  • Pathologists use histology, the microscopic study of tissue, to determine cause of death. They are looking for patterns: cells that are swollen, dead, or abnormally shaped. Those patterns are the clues.
  • Tomorrow you will identify tissue types on real slides and examine a preserved heart. Today we build the knowledge you need to actually recognize what you are looking at.
  • By the end of today you should be able to look at a cross-section of tissue and at least ask the right question: epithelial, connective, muscle, or nerve?
Do this, step by step
  1. 1Take notes on the four primary tissue types and their functions.
  2. 2Map two organ systems to the tissues that build them.
  3. 3Review how a pathologist links tissue damage to cause of death.
  4. 4Complete the PLTW master-the-morgue online task on body systems.
  5. 5Note the observation variables you will record during microscopy.
You'll be able to
  • I can name the four tissue types and their roles.
  • I can connect a tissue to the organ system it serves.
Know by the end
  • The four primary tissue types are epithelial (covering/lining), connective (support/binding), muscle (movement), and nervous (communication).
  • A pathologist identifies cause of death by looking for tissue-level changes such as necrosis, inflammation, or structural damage in histology slides.
  • Organ systems are not independent: the cardiovascular system depends on muscular tissue and connective tissue, and a failure in one tissue type can cascade across systems.

What to do if you were absent

If YOU are absent

Today is individual PLTW work, so do exactly what we did in class, from home: complete the same PLTW target above, then submit your Exit ticket.

Open Schoology (CMSD) and keep going

How to get there: open the CMSD website, click Clever, sign in with your Microsoft (district) account, then open Schoology from Clever.

If MR. MENDOZA is absent
