Arteries |
|
|
Tunica intima |
Inner layer of artery, consists of endothelial cells that line the lumen |
|
Tunica media |
Middle layer of artery, smooth muscle fibers, elastic |
|
Tunica adventitia |
External layer, loose connective tissue |
|
Vasa Vasorum |
Comprised of tiny arteries and veins that supply the walls of the blood vessels |
|
Arteries vs Veins |
Arteries have hollow elastic tubes criticle for steady blood flow, Veins have little elastic tissue/muscle which make them collapseable |
|
Aorta |
Largest major artery in the body |
|
Capillaries |
Minute hair sized vessels connecting the venous and arterial system, walls single layer, nutrients and waste exchange here. |
|
Ascending aorta 3 branches |
Brachiocephalic trunk (rcca, rsa), left common Carotid artery, left subclavian artery. |
|
Depending aorta |
Enters the abdomen through the aortic opening of the diaphragm anterior to the 12th thoracic vertebrae |
|
Abdominal aorta |
Posterior to the left love of the liver, diameter 2-3cm and 1-1.5 at tapering |
|
Common iliac arteries |
|
|
Major arteries inferior to the heart |
|
|
Celiac trunk |
2cm from diaphragm, arises anteriorly and branches into the common hepatic, lft gastric and splenic arteries |
|
CHA |
Common Hepatic Artery, courses at a 90° angle and branches into proper hepatic and gastroduodenal artery. |
|
GDA |
Gastroduodenal artery, courses along the upper border of the head of the pancreas to the Superior portion of the duodenum |
|
LHA |
Left hepatic artery, supplies blood to the caudate love and left lobe of liver |
|
RHA |
Right hepatic artery, supplies blood to the GB and and right lobe of the liver |
|
Left gastric artery |
Anterior to the left of the esophagus and courses along the lesser curvature of the stomach to supply blood to these structures |
|
Splenic artery |
Largest vessel in the celiac trunk, tortuous along the Superior portion of the pancreas, supplies blood to the spleen and stomach |
|
SMA |
Superior Mesenteric Artery arises 1 cm below the celiac artery, posterior to pancreas, follows parallel course along abdominal aorta. |
|
SMA 5 branches |
Inferior pancreatic artery, duodenal artery, colic artery, ileocolic artery, intestinal artery |
|
IMA |
Inferior Mesenteric Artery, supplies the descending colon, sigmoid and Superior rectal arteries. Difficult to visualize with ultrasound. Courses to the left around 3-4th lumbar vertebrae |
|
Phrenic arteries |
Paired, small vessels, arises laterally and supplies the diaphragm |
|
Renal arteries |
Sits just below the SMA, divides into anterior and inferior renal arteries at kidney, duplication is not uncommon, RRA is longer than the LRA and courses posterior to the IFC. |
|
Gonadal arteries |
Arises inferior to the renal artery |
|
Lumbar arteries |
4cm on each side of the aorta, travel laterally and posteriorly, supplies muscle skin, bone, and spinal cord. |
|
Ultrasound of the Aorta |
