Osmosis is known for producing fun and accessible videos that help students learn medicine and health science more effectively. The Osmosis library offers comprehensive coverage of the Pathology, Physiology, and Pharmacology content you need to know for exams like USMLE® Step 1 and COMLEX-USA® Level 1, a full series on the Learning Science methods that inform your study experience at Osmosis, as well as Clinical Sciences to help you succeed on your clerkships. We also offer Osmosis High-Yield Pathology videos.
What are Osmosis High-Yield Pathology videos?
In general, we try to keep Osmosis videos as clear and concise as possible. Students often tell us that a single Osmosis video covers an entire lecture or even 2–3 lectures’ worth of material in 10 minutes or less. And we’re always happy to hear that!
For some of you, though, our basic pathology videos weren’t quite enough. You watched them for class, and you learned a lot, but when it was time for dedicated board prep, you found yourself craving even more efficiency—the highest yield pathology resources possible.
Challenge accepted!
Osmosis High-Yield Pathology videos give you more information on top of your high-yield options. We’ve designed these videos to be one of the best resources for Step 1 prep. The Osmosis High-Yield Pathology video series delivers hyper-focused content that is:
- Highly efficient
- Not redundant
- Specifically focused on key points of common misunderstanding
- Geared towards helping you answer Step 1 questions correctly and confidently
What topics are covered in the Osmosis High-Yield Pathology videos?
Osmosis High-Yield videos offer comprehensive coverage of the pathology fields you’ll need to know for your first set of board exams. The Osmosis High-Yield Pathology video library includes:
- Cardiovascular system
- Endocrine system
- Gastrointestinal system
- Hematological system
- Musculoskeletal, skin, and connective tissue
- Nervous system
- Renal system
- Reproductive systems
- Respiratory system
So, how “high-yield” are these High-Yield Pathology videos?
Extremely. Everything in Osmosis High-Yield Pathology videos can be filed under “need-to-know.” We recommend watching them after you’ve completed our basic pathology videos.

Why should I use Osmosis High-Yield Pathology videos over other resources?
Great question! Let’s count the reasons why Osmosis high-yield is the best high-yield:
- Osmosis videos are shorter and more efficient than our competitors and they’re scripted to make each word count. You get everything you need without the filler you don’t.
- Osmosis videos cover more content more efficiently.
- Osmosis videos are more visually engaging than other medical education tools, with hand-drawn animations (nary a PowerPoint in sight!), memorable sound effects, and of course, those high-yield topics.
- Osmosis videos contain clear and easy-to-understand diagrams, and charts on must-know facts.
- Osmosis videos have case-based memory hooks and use proven learning strategies to help you remember what you’ve studied more easily.
- Osmosis videos have a helpful timeline feature so that you always know where you are in the middle of a video, and can quickly find the information you’re looking for.
Does Osmosis have more high-yield content planned?
We’ve rolled out learning objectives across more and more of our content, so be on the lookout for them!

Learning Objectives
Dr. Maddison Caterine, Director of Curriculum at Osmosis, developed together specific learning objectives to align with our video, notes, and practice questions. These learning objectives give you clear goals to work towards—it’s like a checklist of everything you should know at the end of a video.
Osmosis Step 1 Review Questions
The Osmosis Question Writing team has written practice Step 1-style practice questions that correlate directly with the content you learn from our Step 1 review videos.

Osmosis High-Yield Pharmacology
The Osmosis Content team also developed High-Yield Notes for pharmacology, that were gradually released as they’ve become available.
