Kevin Patton tackles one of A&P’s slimiest subjects: mucus. In this playful but powerful episode, he reveals ten (or eleven) reasons mucus deserves more attention in our teaching. From immunity to fertility, mucus does it all.

“If life hands you a painful irritant, cover it in an iridescent mucus‑like substance until it becomes a pearl.” (Sarah Rosenshine)
Mucus & Mucous
3.5 minutes
What’s the difference between mucus and mucous? One is a noun, the other an adjective—but that subtle difference trips up a lot of students. This short segment makes a strong case for calling out that distinction early and often in your A&P course.
Virtual HAPS Conference
1.0 minute
Need new ideas for your A&P course? This brief segment promotes the upcoming virtual HAPS conference and Kevin’s own flipped-session presentation—packed with audio strategies for teaching.
Mucus: Body-Wide Protector
4.5 minutes
Reasons:
- Mechanical Barrier
- Immunological First Responder
- Homeostasis Helper
Mucus forms a body-wide protective network—physically trapping invaders, launching immune responses with secretory IgA and enzymes, and maintaining pH and hydration across exposed epithelial surfaces.
Gross Episodes
1.0 minute
This short segment encourages instructors to lean into the gross-out moments. Why? Because they’re often where the best learning happens. And yes, that includes mucus, poop, and pee.
Mucus in Motion
4.5 minutes
Reasons:
4. Lubrication
5. Trap-and-Transport System
6. Environmental Sentinel
This segment gets things moving—literally. Mucus lubricates tissues, rides the mucociliary escalator to clear debris from the lungs, and even signals health status through color and consistency changes.
Kerry Hull Honored
0.5 minutes
Kevin pauses to celebrate A&P educator Kerry Hull, who received the HAPS President’s Medal. It’s a quick but heartfelt recognition of excellence and contribution to our teaching community.
Mucus & The Human Story
4.0 minutes
Reasons:
7. Microbiome Mediator
8. Fertility Facilitator
9. Digestive Ally
10. Indicator of Health
In this segment, mucus supports friendly microbes, gets involved in reproduction, protects the gut from self-digestion, and signals health changes. It’s a slimy but vital player in our human physiology narrative.
Running Concept Lists
0.5 minutes
Want to reinforce deeper learning? Use mucus in a running concept list. Kevin explains how this recurring theme links systems and encourages students to build long-lasting conceptual connections.
Mucus is Vital
4.5 minutes
Reasons:
11. Mucus is Vital to Understanding the Human Body
Kevin wraps it all up by calling mucus what it is: vital. It’s not just a side note in A&P—it’s a unifying, system-spanning feature worth revisiting throughout the course.
