1. Arteries & Veins To Know For Practical

2. Parts of Intrinsic Conduction System
Sinoatrial Node (SA node) - the pacemaker; where the action potential originates, starting each heartbeat
As action potential moves, contraction of atria is stimulated
Atrioventricular Node (AV node) - receives action potential from SA node and sends along to…

3. Parts of Intrinsic Conduction System
Atrioventricular Bundle (Bundle of His) – branches off into right and left bundle branches, and then sends action potential along to…
Purkinje Fibers – action potential received begins ventricular contraction at apex and continues contraction back up toward atria, helping to eject blood into pulmonary trunk or aortic arch

4. Labeling The Heart AD: (Left) Pulmonary Artery AE: Left Atrium
BC: Bicuspid (Mitral) Valve
BD: Aortic Semilunar Valve
BE: Left Ventricle
CD: Aorta

5. Labeling The Heart Let’s Also Label… Pulmonary Trunk
Pulmonary Semilunar Valve
Septum
Apex

9. Artery Circulation
Aorta: largest artery in body; exits left ventricle and is divided into three parts
Ascending aorta
Aortic arch
Descending aorta

10. Artery Circulation
Ascending aorta: Where aorta first comes up; right and left coronary arteries branch from here

11. Artery Circulation
Aortic arch: arching posteriorly and to the left and has three branches
Brachiocephalic artery
Left common carotid
Left subclavian artery

12. Aortic Arch Brachiocephalic Right Common Carotid: head
Internal Carotid: brain
External Carotid: face

13. Aortic Arch Brachiocephalic Right Subclavian: right upper limb
Turns into axillary at armpit
Turns into brachial
Branches into radial and ulnar
Joins back & forms deep palmar arch, superficial palmar arch, and digital arteries

15. Aortic Arch Left Common Carotid: head Internal Carotid: brain
External Carotid: face

18. Aortic Arch Left Subclavian: left upper limb
Branches in the same way that Right Subclavian does

19. Aorta Descending Aorta
Thoracic Aorta: portion in thorax, above diaphragm.
Abdominal Aorta: below diaphragm; ends as two common iliac arteries

20. Abdominal Aorta Celiac Trunk: spleen, stomach, and liver
Renal: Kidneys
Splits into Right & Left Common Iliac Arteries

22. Right & Left Common Iliac
Splits into…
Internal Iliac Artery: bladder, rectum, genitalia
External Iliac Artery:
turns into Femoral Artery: thigh
Turns into Popliteal Artery: knee area
Branches into Anterior & Posterior Tibial Arteries and Fibial Artery: lower leg & foot

24. Vein Circulation Three Major Sections emptying back into right atrium…
Coronary Sinus: Great, Anterior, Small, and Middle Cardiac Veins
Superior Vena Cava
Inferior Vena Cava

25. Upper Body
Superior Vena Cava: receive blood from head, neck, and upper extremities; splits into…
Right and Left Brachiocephalic
Internal Jugular: Brain
External Jugular: Face
Turns into Subclavian…

26. Subclavian Turns into axillary at armpit, which breaks into… Cephalic
Brachial
Radial
Ulnar
Digital
Basilic
Median Cubital joins it back up with Cephalic; often, a site of drawing blood
Deep palmar arch, superficial palmar arch, and digital veins

28. Lower Body Inferior Vena Cava Hepatic Veins: liver
Hepatic Portal: Takes blood from the digestive tract, spleen, pancreas to the liver
Renal: Kidneys
Splits into Right & Left Common Iliac Veins

29. Right & Left Common Iliac
Internal Iliac Vein
bladder, rectum, genitalia
External Iliac Vein
Great Saphenous: branches off, runs along femur, longest vein in body
EIV turns into Femoral Vein: thigh
Turns into Popliteal Vein: knee area
Branches into Anterior & Posterior Tibial Veins and Fibular Vein: lower leg & foot
