Blood Vessels

3. Pulmonary Circuit

4. Systemic Circuit

5. Arteries:
Veins:

6. Elastic (Large) Arteries: Aorta, pulmonary trunk, & their close branches
Large Veins:
Return blood to heart
Medium Veins:
Gather blood from head, limbs, & organs
Muscular (Medium) Arteries: Distribute blood to head, limbs, & organs
Small Veins:
Gather blood from tissues
Arterioles:
Distribute blood within organs & tissues
Venules:
Gather blood from capillaries. Also some exchange of same materials as capillaries
Capillaries:
Primary site for exchange of gases, nurients, ions, wastes, hormones, cells, etc.

7. Pathway Variations:

8. Entire circulatory system (heart, all vessels) lined
Capillaries
Larger vessels, either veinous or arterial,

9. You will be asked to know the names of some specific arteries and veins, but first it is important to understand the patterns which these vessels form.

10. “Great Vessels”
Not visible:

11. Arteries Arising From Arch of Aorta

16. Veins which drain blood from the neck and head (including brain)

17. In upper limb,

18. Upper limb also has

19. In abdomen, aorta gives rise to two sets of arteries:1. 2.

20. In abdomen, also two sets of veins:1. 2.

21. Deep Veins
In lower limb

22. Superficial Veins
Lower limb also has

23. You should be able to identify the following arteries, know from where each artery receives blood, and know to where each artery delivers blood.
Aorta Pulmonary trunk
Brachiocephalic artery Pulmonary arteries
Subclavian arteries Common carotid arteries
Axillary arteries Internal carotid arteries
Brachial arteries External carotid arteries
Radial arteries Vertebral arteries
Ulnar arteries Basilar artery
Common iliac arteries Renal arteries
Internal iliac arteries Celiac trunk
External iliac arteries Hepatic artery
Femoral arteries Splenic artery
Popliteal arteries Left gastric artery
Anterior tibial arteries Superior mesenteric arteries
Posterior tibial arteries Inferior mesenteric arteries
Gonadal arteries Coronary arteries
Example: Each external iliac artery receives blood from the common iliac artery on that side and delivers blood to the femoral artery on that side

24. You should be able to identify the following veins, know from where each vein receives blood, and know to where each vein delivers blood.
Superior vena cava Hepatic portal vein
Inferior vena cava Splenic vein
Brachiocephalic veins Inferior mesenteric vein
Subclavian veins Superior mesenteric vein
Axillary veins Common iliac veins
Brachial veins Internal iliac veins
Radial veins External iliac veins
Ulnar veins Femoral veins
Cephalic veins Popliteal veins
Basilic veins Anterior tibial veins
Median cubital veins Posterior tibial veins
Vertebral veins Greater saphenous veins
Internal jugular veins Lesser saphenous veins
External jugular veins Gonadal veins
Example: Each external iliac vein receives blood from the femoral vein on that side and delivers blood to the common vein on that side
