Histology Slides for the Cardiovascular System
• Slides are presented in order of magnification• As you view the following slides, make sure you
can accomplish these goals:1. Can you identify the vessels and tissue layers
observable on the slides?2. Can you identify the specific structures or
layers indicated by the numbered arrows or brackets?
• At the end of a sequence, you will find the answers to the above for each vessel and layer
