Lines the the lumen of the vessel, is a single layer of endothelium that is continuous with the endocardium of the heart. Helps decrease friction as blood flows through the vessels

Muscular middle layer in blood vessels made primarily of smooth muscle and elastic tissue; the tunica mesida of arteries is more muscular than that of veins.

[image]

The ourtermost tunic, is composed of fivrous connective tissue. Its function is to supposet and protect vessels.

1. Ascending Aorta
2. Aortic Arch
3. Thoracic Aorta
4. Abdominal Aorta

The only branches of the ascending aorta are:

• Right coronary artery
• Left coronary artery

Which supply the Myocardium

1. Brachialcephalic Trunk
   -Right common carotid artery
   -Right subclavian artery
2. Left common carotid artery
3. Left subclavian artery

Each divides to form an

• Internal carotid artery: which serves the brain
• External carotid artery: Which supplies the tissues external to the skull in the neck and head.

• Give off several branches to the head and neck
• Vertebral artery: first of these branches; runs up the posterior neck to supply the cerebellum, brain stem, and the posterior cerebral hemispheres.
• Becomes the axillary artery in the armpit which serves upper limb.

• Gives off several branches to the chest wall and shoulder girdle
• Axillary artery becomes the Brachial artery as it enters the arm
• Brachial artery divides into
  • radial artery
  • ulnar artery

• Celiac trunk: breaks into 3 branches
  
  • L Gastric artery
  • Splenic artery
  • Common Hepatic artery which becomes the Hipatic artery proper as it runs to serve the liver
• Superior Mesenteric artery 
• Renal arteries
• Gonadal arteries
  • Ovarien arteries (female)
  • Testicular arteries (male)
• Inferior Mesenteric artery
• Common Iliac arteries

Is an unpaired artery that divides almost immediatley into three branches:

• L Gastric artery: supplying the stomach
• Splenic artery: supplying the spleen
• Common Hepatic artery: gives off branches to the stomach, small intestine, and pancreas
  • becomes the Hepatic artery Proper as it runs to serve the liver

• most of the small intestine
• first half of large intestine

• Paired arteries
• supplies kidneys

• arise from ventricle aortic surface just below renal arteries
• serve gonads
• Also known as:
  
  • Ovarian arteries (female)
  • Testicular arteries (males)

• Supplies distal half of large intestine
• four pairs of lumbar arteries arise from the aorta and supply posterior abdominal wall

• Common iliac arteries
  
  • internal iliac artery
  • external iliac artery
    • changes to femoral artery
    • changes to popiteal artery
      • Anterior tibial artery
        • Changes to Dorsalis pedis artery
        • Arcuate artery
      • Posterior tibial artery

• Serves the pelvis
• lower abdominal wall
• lower limbs

• supplies gluteal muscles
• adductor muscles of medial thigh
• and genitals

• anterior abdominal wall
• lower limbs
• In thigh name changes to Femoral artery

• supply head of the femur
• hamstring muscles
• gives of deep branch: Deep Femoral artery
  
  • supplies the posterior thigh

• Branched from femoral artery
• subdivides to
  • anterior tibial artery- supply leg and foot
    • terminates in dorsalis pedis artery
      • arcuate artery
  • posterior tibial artery- same

The veins of the hepatic portal circulations drain:

• digestive organs
• spleen
• pancreas

and deliver this blood to the liver via the Hepatic Portal vein
