Laboratory Objectives: After learning, the students were able to
1. Identify the basic components of the heart wall and blood vessels2. Identify the heart wall layers and heart valve3. Identify Purkinje fibers in subendocardium4. Identify the difference characteristics of the vein and artery; including vasa vasorum notice5. Compare the characteristic of the large artery, medium artery, arteriole and capillary
6. Compare the characteristic of the large vein, medium vein and venule

Fig.1.4 ArterioleNotice :
1. The small arteriole has 3-5 endothelial cells in tunica intima .2. It has smooth muscle in the tunic 3-5 layers or more in large arteriole.3. Its tunic can not be markedly divided except in large arteriole.

Notice:1. It has 1-2 endothelial cells (E) on the
basal lamina.2. The pericyte cells (P) wraps around
the vessels.
