What is a coagulation cascade diagram?

It is a figure of the clotting-factor sequence that turns a vessel injury into fibrin. The usual teaching layout is three paths — intrinsic, extrinsic, and common — meeting at Factor X. This tool draws that layout, or a simpler or annotated variant, from a description.

Can I make a labeled and a blank cascade for the same lecture?

Yes. Generate a fully labeled classical cascade first, then ask for the same layout with empty boxes. That pair is the teaching set: one to show, one to quiz. A third, simpler slide is optional for a mixed-level room.

Will this replace the NIH or Osmosis cascade figure?

No. Those pages already have the canonical what-is diagram. Use this page when you need a custom lecture variant: blank, simpler, drug sites, hemophilia, or cell-based vs classical — not when you only need to look up the pathway.

Can I mark heparin, warfarin, or DOAC sites?

Yes. Ask for anticoagulant action sites on the classical cascade. Typical teaching marks: heparin via antithrombin on Xa/IIa, warfarin on II/VII/IX/X, and most DOACs on Xa. Always check the labels before you teach from the figure.

Classical cascade or cell-based model?

Default to the classical Y-shape unless you ask otherwise. For a review slide, you can request a side-by-side of classical vs cell-based (initiation, amplification, propagation) with matching factor names.

Are the factor numbers guaranteed correct?

No. This is an AI illustration, not a deterministic SVG of a fixed map. Confirm Roman numerals, cofactors, and lab-test notes (PT vs aPTT) against a trusted source before you use the figure in class or a paper.

Coagulation Cascade Examples

Labeled, blank, simpler, and annotated lecture figures — not a what-is page

Labeled Classical Cascade

The lecture original: intrinsic, extrinsic, and common paths, factors named, fibrin at the end.

Blank Self-Test

Same topology, labels removed — the second artifact in a teaching set.

Simplified Lecture Slide

Fewer boxes, larger type — the simpler PPT for the same hour.

Hemophilia A Break

VIII missing, aPTT path broken, PT path intact — a figure you can stand in front of.

What this page makes (and what it does not)

This page makes a coagulation cascade figure you can take to a lecture or drop into a review: labeled, blank for self-test, simpler for a first slide, or annotated with a drug or a disease break. It does not replace the NIH or Osmosis “what is the clotting cascade” explainer. Those pages already own the canonical picture. The job here is a custom variant of that topology — the set a tutor or lecturer actually pays to finish.

Classical pathways the diagram should lock

Intrinsic (contact) path: XII → XI → IX, with VIII as a cofactor, measured by aPTT.
Extrinsic (tissue-factor) path: TF + VII, measured by PT / INR.
Common path: X (with V) → II (prothrombin → thrombin) → I (fibrinogen → fibrin).
Cofactors often worth labeling: Ca2+, phospholipid / platelet surface, and vitamin K for II, VII, IX, and X.

Labeled, blank, and simpler — one topic, three artifacts

A paying teaching workflow is usually a pack, not a single download. Start with a fully labeled classical cascade so the room can see every factor. Make a blank copy of the same layout for a self-test. Then make a simpler slide that keeps TF → VII → X → thrombin → fibrin if the audience is nursing or first-year. Ask for those three outputs in three prompts; do not expect one image to be both the atlas and the quiz.

Drug sites and disease breaks

The cascade becomes a clinical figure when you mark where a drug or a missing factor sits. Unfractionated heparin works through antithrombin on Xa and IIa. Warfarin hits the vitamin-K–dependent factors II, VII, IX, and X. Direct oral anticoagulants typically block Xa (or thrombin, for dabigatran). Hemophilia A removes VIII and lengthens aPTT while PT stays normal. Describe the annotation you need; the generator should keep the same three-path layout underneath so the class can still read it.

Classical Y-shape vs the cell-based model

Most exam slides still use the Y-shaped classical cascade. Many hematology courses also teach the cell-based model: initiation on tissue-factor–bearing cells, amplification on platelets, then propagation of a thrombin burst. If you need both, ask for a two-panel figure with the same factor names in each panel. Do not mix the two models into one unlabeled tangle.

Honesty note on AI factor labels

These are AI illustrations. The model can swap Roman numerals, drop a cofactor, or put heparin on the wrong node. That is why this page is a lecture-pack generator and not a Precise SVG engine: the topology branches, and a boxy “correct” renderer would look like a stacked org chart. Check every factor against your textbook, Osmosis, or a hematology atlas before you project the slide or put it in a paper. Treat the file as a draft you verify.
