Blood Vessels, part 1 - Form and Function: Crash Course A&P #27

Now that we've discussed blood, we're beginning our look at how it gets around your body. Today Hank explains your blood vessels and their basic three-layer structure of your blood vessels. We're also going over how those structures differ slightly in different types of vessels. We will also follow the flow of blood from your heart to capillaries in your right thumb, and all the way back to your heart again.
