Body systems and tissues
Wed, Sep 23, 2026 · Week 5 · Principles of Biomedical Technology (Principles of Biomedical Science)
Today's goal: Relate organ systems to tissue types and prepare for the PLTW morgue task.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Four tissue types, a feature, and an organ:
- Epithelial: tightly packed cells that cover and line surfaces; found in the skin.
- Connective: cells spread in a matrix that supports and binds; found in bone.
- Muscle: long fibers that contract; found in the heart.
- Nervous: branching cells that send signals; found in the brain.
Why it matters: organs are built from combinations of these four, so recognizing them is the first step a pathologist takes when reading a slide.
| Tissue type | Feature | Organ example |
|---|---|---|
| Epithelial | Covers and lines surfaces | Skin |
| Connective | Matrix supports and binds | Bone |
| Muscle | Fibers that contract | Heart |
| Nervous | Cells that send signals | Brain |
This model shows the level of evidence and organization needed to complete: An exit ticket naming the four primary tissue types, one structural feature of each, and one organ that contains each, checking recall before microscopy.
- Name the prompt or task.
- Answer it directly with the key evidence.
- Check that the response matches the requested format.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Hand in your exit ticket before leaving class. Also complete the online master-the-morgue body-systems task.
Claim ceiling: Today's evidence supports a classroom claim about today's lesson. It cannot prove causation, diagnose a real patient, or justify action outside this room.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Identifying the four primary tissue types and their roles.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
