Learn to recognize every tissue under the microscope, find where it lives, and watch a wound heal. Nothing here is graded.

What tissue is this?

Giveaway features (numbered on the image)

Every image is drawn fresh, so the same tissue never looks exactly the same twice, just like real slides.

Tap any card to enlarge it with labels. Toggle the schematic to see the same image as a clean diagram.

Answer each question about this image. Wrong turns are fine: you can try again.

Tip: this tree is the same set of questions an expert asks, in the same order.

Keyboard or switch users: pick a location by name here instead of tapping the map.

Where does it live, and what does it do?

1. Tap a tissue card. 2. Tap where it is found on the body map. 3. Pick its job.

Wound

Bacteria get in Antihistamine

Changes apply on the next injury. The last run stays on the graph as a dashed line so you can compare.

Predict first: how will this wound heal?

Ready. Press "Injure the tissue".

Challenges

Simplified teaching model: time is squeezed (minutes to weeks) and curve heights are relative, not measured values.

Every microscope image here is generated by code to imitate an H&E-stained slide (reticular tissue imitates a silver stain, elastic tissue an elastic stain, and bone a ground section). They are teaching drawings, not photographs. Diagrams are simplified and not to scale.
