CARDIOVASCULAR LABORATORY
IMAGES
The purpose of this exercise is to examine the microscopic feature of the Cardiovascular System comprised of the Blood Vascular System and the Lymphatic Vascular System.

The Blood Vascular System is comprised of the heart, arteries (large, medium, and small), arterioles, capillaries, venules, veins, and sinusoids.

The Lymphatic Vascular System is comprised of Lymphatic capillaries and Lymphatic vessels

The circulatory system constitutes the transportation system for the blood and lymph. all cells have access to this system, usually by way of tissue fluid. The circulatory systems is maintained by the pumping action of the heart. The tubes of this system are arranged in the form of a circuit by which blood is delivered to and brought back from all parts of the body.

Within the cardiovascular system there is a fundamental plan. An understaning of this plan will enable you to distinguish the various structures in this system.

Within the vascular system, three layers are recognised: Tunica intima, Tunica media, and Tunica adventitia. Three layers are present in the heart: Endocardium, myocardium, and epicardium (epicardium + mesothelium = visceral pericardium).

B
e able to distinguish each of the structures of this system and recognize their salient features as described in the text associated with each of the images.
