Formed Elements of Blood neutrophil eosinophil erythrocyte - PowerPoint PPT Presentation

Histology of Blood Cells, Cardiac Muscle, Blood Vessels and Lymphatics

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

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.
