Tissue and heart lab
Thu, Sep 24, 2026 · Week 5 · Principles of Biomedical Technology (Principles of Biomedical Science)
Today's goal: Examine histology slides under the microscope and observe gross heart anatomy following an SOP.
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.
Histology sketches (Andre, Period 4):
- Epithelial at 100x: tightly packed cells, labeled.
- Connective at 100x: scattered cells in a matrix, labeled.
- Muscle at 100x: long striated fibers, labeled.
- Nervous at 100x: branching cell with extensions, labeled.
Heart diagram: labeled right and left atria, right and left ventricles, tricuspid and mitral valves, aorta and pulmonary artery.
Limitation: A thick slide section overlapped cells, making one tissue hard to identify. Error source: focusing at the wrong magnification could make a structure look larger than it is, so I recorded magnification on each sketch.
| Structure | Type |
|---|---|
| Right and left atria | Chambers |
| Right and left ventricles | Chambers |
| Tricuspid and mitral | Valves |
| Aorta and pulmonary artery | Major vessels |
This model shows the level of evidence and organization needed to complete: Notebook pages with four histology sketches (magnification and one feature labeled) and a labeled heart diagram with chambers, valves, and major vessels, plus a limitation and error source.
- State the question and method.
- Present the observations and data with units.
- Explain the result, limitations, and next investigation.
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: Photograph your notebook pages and upload to the tracker before leaving class.
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: Recording magnification with microscopy sketches and locating heart structures.
- 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.
