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.
What a finished product looks like
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 |
Also due today: Photograph your notebook pages and upload to the tracker before leaving class.
