Formed Elements of Blood neutrophil eosinophil erythrocyte monocyte lymphocyte platelets basophil • Formed Elements = Erythrocytes, Leukocytes, Platelets • Non-formed Elements = Plasma Three neutrophils and a lymphocyte. Two eosinophils. A neutrophil and a monocyte. A monocyte and a neutrophil. A monocyte, neutrophil, lymphocyte, and basophil. A monocyte A lymphocyte and a neutrophil. One small lymphocyte, a larger lymphocyte and an eosinophil. An eosinophil and small lymphocyte. A neutrophil, and a basophil. platelets. Cardiac Muscle = Myocardium The Structure of Blood Vessels • Tunica Interna (also called the Tunica Intima) – smooth inner layer that repels blood cells and platelets – endothelium of simple squamous cells on a basement membrane • Tunica Media – middle layer of smooth muscle, collagen, elastic fibers – smooth muscle causes vasoconstriction and vasodilation • Tunica Externa (also called the Tunica Adventitia) – outermost layer of loose connective tissue – holds vessels in place Blood Vessel Layers http://www.siumed.edu/~dking2/crr/cvguide.htm#vessels Veins and Arteries http://www.siumed.edu/~dking2/crr/CR025b.htm Aorta 1 Tunica Intima 2 Tunica Media 3 Tunica Adventitia http://www.histol.chuvashia.com/atlas-en/circulatory-en.htm Lymph Vessels and Lymph Node Lymph Node capsule Germinal Centers http://education.vetmed.vt.edu/Curriculum/VM8304/lab_companion/Histo-Path/VM8054/Labs/Lab13/EXAMPLES/Exlymnod.htm lymphocytes Lymph Vessel and a Small Vein Lymphatic vessel (L) next to a small vein (V). Lymphatics due not contain RBCs, but often contain a few lymphocytes. Taken from Wheater’s Functional Histology, a text and colour atlas, p. 156, Figures 8.22 and 8.23. A lymph vessel valve (V).
