Use this KWL chart to track your learning about the circulatory system. Add posts to:

What I Know (K) : Share your current knowledge about the circulatory system
What I Want to Know (W) : Post questions you have before starting the unit
What I Learned (L) : Add new information you learn about:
- Components of blood
- Heart and blood vessel structure/function
- Blood flow path through heart, lungs, and body
- Heart rate, blood pressure, and perfusion

Still Wondering (SW) : Add remaining questions after completing the unit

Basics of the Circulatory System

2025-09-09 23:30:42 UTC

The circulatory system is composed of the heart, arteries, veins, and capillaries which pump oxygenated blood around the body and pump deoxygenated blood to capillaries in the lungs where haemoglobin in red blood cells binds to oxygen and takes up the gas.

Responding to a Circulatory Issue

What is the order in which we respond to a circulatory problem in a patient? Which steps are taken first in order to respond quickly?

General Circulation Knowledge

Foundational understanding of circulation and the electrical impulses of the heart. We also touched on clotting factors, blood pressure, and the differences between capillaries, veins, and arteries that affect their function and structure.

Most Made Mistakes

I'm wondering what the most looked past circulation issue is that you've seen as a paramedic. What issues do new paramedics make when it comes to circulation?

Vein and Artery Structure

I found it interesting and helpful that vessel structure is reflective of the function (like all biology). Veins move blood toward the heart and are at low pressures, making them appear floppy and flat, though suction from valves keeps circulation flowing in the veins. Arteries are more firm and structured due to being at high pressures, they also had thicker walls than veins.
