1. SUBMITTED TO: Dr. Zeeshan Akbar SUBMITTED BY: Waqas Nawaz 11-arid-975 BRANCHES OF THORACIC & ABDOMINNAL AORTA

2. Branches of thoracic aorta In addition to the coronary arteries and common brachio -cephalic trunk, the thoracic part of aorta gives off branches to the thoracic walls and viscera and to spinal cord and its membrane. (1). Viseral branches…………….bronchial and oesophageal (2).parietal branches………….. intercostal and phrenic

3. (1) Visceral Branches Bronchial- oesophageal artery: Origin: arises at the sixth thoracic vertebra from aorta-it descends over the right face of the aorta towards bifurcation of trachea and divided into bronchial anaoesophagial branches. Bronchial Artery : It crosses the left face of oesophagous to the bifurcation of trachea where it divides into right and left branches.Each enter into hilus of corresponding lung.

4. Cont… Oesophageal Artery : It is small vessel which passes backward dorsal to the oesophagous in the posterior mediastinum and anastomosis with the oesophageal branch of the gastric artery and gives off branches which passes between the layers of ligament of the lungs.

5. Parietal Branches: Intercostal arteries: *first arise from deep cervicle artery *Next three arise from subcostal branch of dorsal artery *remainder arise from aorta 1. Aorticintercostals arteries : Arise from aorta in paires close together. The fifth and sixth springs from a common stem. each passes the body of vertebra to intercostals space. It divides into Dorsal branches Venteral branches

6. Dorsal branches: It gives off spinal branches which passes through interverteberalforamen.a muscular branch passes to muscle and skin of back.   Venteral branches: It is much large. Origin: it descend in middle of intercostals space between intrcostal muscles. Supplies: it supplies intercostalsmuscle,theribs,and pleura  

7. Pharenic arteries: Origin: two or three small branches which arise at hiatus aorticus from venteral aspect of aorta. Supplies: they supplies crura of diapgram .

8. BRANCHES OF ABDOMINAL AORTA: THESE BRANCHES SUPPLIES WALLS OF ABDOMINAL CAVITY SOME BRANCHES SUPPLIES SPINAL CORD SOME EXTEND INTO PELVIS AND SACROTUM

9. VISCERAL BRANCHES (1).COELIAC ARTERY IT IS UN PAIRED VESSEL ORIGIN: ARISE FROM VENTERAL ASPECT OF AORTA IT IS FURTHER DIVIDED INTO THREE BRANCHES GASTRIC ARTERY IT GIVES OFF OESOPHAGOUS AND PANCREATIC BRANCHES IT DIVIDED BEHIND THE CARDIA INTO ANTERIOR AND POSTERIOR BRANCHES

10. Cont… ANTERIOR BRANCHES: THEY SUPPLIES THE PARIETAL SURFACE OF STOMACH POSTERIOR BRANCHES: THEY SUPPLIES THE VISCERAL SURFACE OF STOMACH OESOPHGEAL BRANCHES: IT PPASSES THROUGH HIATUS OESOPHAGOUS INTO THORACIC CAVITY ABOVE THE OESOPHAGOUS AND ANASTOMOSES WITH THE OESOPHAGEAL BRANCH OF BRONCHO-OESOPHAGEAL CAVITY.

11. HEPATIC ARTERY: LARGER THAN GASTRIC IT PASSES FORWARD AND TO THE RIGHT AND VENTERALLY ON DORSAL SURFACE OF PANCREAS IT DIVIDED INTO 3-4 BRANCHES WHICH ENTER THE PORTAL FISSURE OF LIVER IT ALSO GIVES OFF CO-LATERAL BRANCHES PANCREATIC BRANCHES: GIVES OFF AN ARTERY CROSSES THE PANCREAS   PYLORIC ARTERY: ORIGIN: ARISE FROM DUOENUM AND GIVES OFF ITS BRANCHES TO PYLORUS.   GASTRO-DUODENAL ARTERY: ORIGIN: IT ALSO ARISE FROM DUODENUM IT ALSO GIVES TWO BRANCHES.   RIGHT GASTRO EPIPLOIC ARTERY: IT SUPPLIES STOMACH AND DUODENUM PANCREATIC-DUEDENAL ARTERY: IT SUPPLIES PANCREAS AND DUEDENUM  

12. SPLENIC ARTERY: LARGEST BRNCH OF CORLIAC ARTERY. IT PASSES THE LEFT EXTRIMITY OF PANCRAS AND CROSS THE STOMACH. IT GIVES OFF   PANCREATIC BRANCHES: SUPPLIES : THEY SUPPLIES THE LEFT EXTRIMITY OF PANCREAS   SPLENIC BRANCHES: SUPPLIES: THEY SUPPLIES THE SPLEEN SHORT GASTRIC BRANCHES : SUPPLIES :IT SUPPLIES YHE GREATER CURVATURE OF STOMACH   LEFT GATRO EPIPLOIC ARTERY: IT IS CONTINUATION OF SPLENIC ARTERY SUPPLIES: IT SUPPLIES THE GREATER CURVATURE OF STOMACH

13. (2) ANTERIOR MESENTRIC ORIGIN: ARISE FROM VENTERAL FACE OF AORTA AT FIRST LUMBER VERTEBRA. IT IS LARGE UNPAIRED TRUNK IT PASSES VENTERALLY BETWEEN VANA CAVA AND ADRENAL IT GIVES OFF BRANCHES …..

14. LEFT BRANCH: IT GIVES OFF 15-20 BRANCHES OF SMALL INTESTINE RIGHT BRANCHES: IT GIVES OFF SMALL BRANCHES ILEAL: IT PASSES THE TERMINAL PART OF ILEUM LATERAL COCCYGEAL ARTERY: IT PASSES BETWEEN COECUM AND ORIGIN OF COLON MEDIAL COCCYGEAL ARTERY: IT PASSES ALONG THE APEX OF COECUM

15. VENTERAL COLIC ARTERY: IT PASSES THE VENTERAL SURFACE OF COLON WHERE IT UNITES WITH DORSAL COLIC ARTERY ANTERIOR BRANCHES : IT GIVES OFF DORSAL COLIC ARTERY: IT PASSESS THE GREATER COLON AND JOINS THE VENTERAL COLIC ARTERY MEDIAL COLIC ARTERY: IT PASSES THE SMALL COLON AND ENTER THE COLIC MESENTRY

16. RENAL RIGHT & LEFT ARE RELATIVELY LARGE NESSELS WHICH ARISES FROM AORTA NEAR THE ANTERIOR MESENTRIC. RIGHT ARTERY: IT IS LONGER OF THE TWO; IT CROSS THE DORSAL SURFACE OF VENA CAVA AT RENAL HILUS IT DIVIDES INTO SEVERAL BRANCHES LEFT ARTERY: IT IS SHORTER; IT PASSES DIRECTLY OUTWARD TO THE KIDNEY SOME CO-LATERAL BRANCHES SUPPLIED & UTERUS , PERITONIAL FAT, RENAL LYMPH GLAND & ADRENAL

17. ( 4)POSTERIOR MESENTRIC IT IS AN UNPAIRED VESSEL WHICH ARISES FROM VENTRAL SURFACE OF AORTA AT THE 4 TH LUMBER VERTEBRA. IT SUPPLIES THE SMALL COLON & RECTUM ANTERIOR BRANCH POSTERIOR BRANCH ( 5)INTERNAL SPERMATIC/UTERO-OVARIAN IT ARISES FROM AORTA NEAR THE POSTERIOR MESENTRIC & SUPPLY THE TESTICLE AND EPIDIDYMUS. EACH PASSES BACKWARD IN A NARROW FOLD OF PERITONIUM TO THE INTRNAL INGUANUL RING & DESENDS THOUGH INGUINAL CANAL TO THE SACROTUM.
