Presentation Transcript

  1. The blood vessels

  2. The blood vascular system The heart The capillaries The arteries The veins carry deoxygenated blood, rich in carbon dioxide and other metabolic products from the tissues to the heart pumps the blood carry oxygenated blood and nutrients to the tissues consists of a diffuse network of thin tubules through which gas exchange between blood and tissues takes place

  3. THE STRUCTURE OF THE ARTRIES AND VEINS • Composed of three layers: • Tunica intima • Tunica media • Tunica adventitia

  4. TUNICA INTIMA • Two components: • Squamous endothelial cells: • Rest on a basal membrane (Basal lamina). • Line the interior surface. • Sub endothelial layer: • Loose connective tissue • Smooth muscles arranged longitudinally.

  5. TUNICA MEDIA • Smooth muscle cells. • Collagen and elastic fibers in-between.

  6. TUNICA ADVENTITIA • Connective tissue rich in collagen and elastic fibers

  7. THE ARTERY • Tunica intima: • Separated form tunica media by a layer of connective tissue called internal elastic lamina. • Tunica media: • The thickest layer • Tunica adventitia: • Rich in elastic fibers T.S in Artery

  8. THE VEIN Tunica intima: Does NOT have internal elastic lamina. Tunica media: The thinner layer Tunica adventitia: The Thickest layer Rich in collagen fibers. T.S in Vein

  9. COMPARISON BETWEEN ARTERY AND VEIN
