1. Circulatory system

2. 1. Circulatory system 2. Blood vascular system 3. Blood vessels: a) Arteries; b) Veins; c) Microcirculatory bed 4. Lymphatics 5. Heart

3. Scheme of vessel’s wall 1. Intima: a) endothelium; b) subendothelial layer 2. Media (sm. myocytes+ fibers) 3. Adventitia (loose con. tissue)

4. 1. Intima: a) Endothelium; b) Subendothelial layer; c) Internal elastic lamina 2. Media (sm. myocytes+ fibers) 3. Adventitia (loose con. tissue+ vasa vasorum)

5. Classification of the artery 1.Elastic type (aorta) 2.Muscular elastic type 3.Muscular type

6. 1. Intima: a) Endothelium; b) Subendothelial layer; c) Internal elastic lamina 2. Media (sm. myocytes+ fibers) 3. Adventitia (loose con. tissue+ vasa vasorum)

7. Elastic artery 1. Large endothelial cells 2. Subendothelial layer (myointimal cells) 3. Elastic fibers predominate

8. Muscular artery 1. Thin intima 2. Myocytes predominate 3. Internal elastic lamina well defined

9. Artery-vein 1. Thin wall 2. Bigger diameter (irregular shape) 3. Collagen fibers (laminas) 4. Adventitia thick 5. Walves

10. Microcirculatory bed

11. Capillary

13. Somatic capillary

14. Fenestrated capillary

15. Anastomoses AVA functions are the next: 1.Regulation (correction) of the blood pressure. 2.Blood supplying of organs. 3.Venous blood saturation with oxygen. 4.Blood withdrawing from the depot. 5.Regulation of the tissues fluid passage to the venous bed. Types: typical+ nontypical

17. Lymphatic vessels

19. Lymphatic vessel

20. Heart

21. HEART Tunices: 1. Endocardium (endothelium, subendothelial layer, fibro-muscular and external connective tissue layer) 2. Myocardium (contractile and conductive myocytes) 3. Epicardium 4. Pericardium

22. Types of cardiomyocytes: 1.Typical (contrictile) 2.Nontypical: a)Condictive b)Endocrine cardiomyocytes

29. Purkinje fibers

30. Atrial endocrine cardiomyocytes
