Blood Vessels
BLOOD VESSELS Blood vessels are how blood travels through the body. Whole blood is a fluid made up of red blood cells (erythrocytes), white blood cells (leukocytes), platelets (thrombocytes), and plasma. It supplies the body with oxygen. SUPERIOR AORTA (AORTIC ARCH) VEINS & VENA CAVA ARTERIES There are two basic types of blood vessels: veins and arteries. Veins carry blood back to the heart and arteries carry blood from the heart out to the rest of the body. Factoid! The smallest blood vessel is five micrometers wide. To put into perspective how small that is, a strand of hair is 17 micrometers wide! 2 BASIC (ARTERY) BLOOD VESSEL TUNICA EXTERNA TUNICA MEDIA (ELASTIC MEMBRANE) STRUCTURE TUNICA MEDIA (SMOOTH MUSCLE) Blood vessels have walls composed of TUNICA INTIMA three layers. (SUBENDOTHELIAL LAYER) The tunica externa is the outermost layer, primarily composed of stretchy collagen fibers. It also contains nerves. The tunica media is the middle layer. It contains smooth muscle and elastic fiber. TUNICA INTIMA (ELASTIC The tunica intima is the innermost layer. MEMBRANE) It contains endothelial cells, which TUNICA INTIMA manage substances passing in and out (ENDOTHELIUM) of the bloodstream. 3 VEINS Blood carries CO2 and waste into venules (super tiny veins). The venules empty into larger veins and these eventually empty into the heart. The walls of veins are not as thick as those of arteries. Some veins have flaps of tissue called valves in order to prevent backflow. Factoid! Valves are found mainly in veins of the limbs where gravity and blood pressure VALVE combine to make venous return more 4 difficult. -

McCarthy, MD a Objective: We sought to determine the role of partial left ventriculectomy in Randall C. Starling, MD b patients with dilated cardiomyopathy. Methods: Since May 1996 we have James Wong, MBBS, PhD b performed partial left ventriculectomy in 53 patients, primarily (94%) in Gregory M. Scalia, MBBS b heart transplant candidates. The mean age of the patients was 53 years Tiffany Buda, RN a Rita L. Vargo, MSN, RN a (range 17 to 72 years); 60% were in class IV and 40% in class III. Marlene Goormastic, MPH c Preoperatively, 51 patients were thought to have idiopathic dilated cardio- James D. Thomas, MD b myopathy, one familial cardiomyopathy, and one valvular cardiomyopathy. Nicholas G. Smedira, MD a As our experience accrued we increased the extent of left ventriculectomy James B. Young, MD b and more complex mitral valve repairs. For two patients mitral valve replacement was performed. For 51 patients the anterior and posterior mitral valve leaflets were approximated (Alfieri repair); 47 patients also had ring posterior annuloplasty. In 27 patients (5!%) one or both papillary muscles were divided, additional left ventricular wall was resected, and the papillary muscle heads were reimplanted. Results: Echocardiography showed a significant decrease in left ventricular dimensions after resection (8.3 cm to 5.8 cm), reduction in mitral regurgitation (2.8+ to 0), and increase in forward ejection fraction (15.7% to 32.7%). -

Fetal Descending Aorta/Umbilical Artery Flow Velocity Ratio in Normal Pregnancy at 36-40 Weeks of Gestational Age Riyadh W Alessawi1
American Journal of BioMedicine AJBM 2015; 3(10):674 - 685 doi:10.18081/2333-5106/015-10/674-685 Fetal descending aorta/umbilical artery flow velocity ratio in normal pregnancy at 36-40 Weeks of gestational age Riyadh W Alessawi1 Abstract Doppler velocimetry studies of placental and aortic circulation have gained a wide popularity as it can provide important information regarding fetal well-being and could be used to identify fetuses at risk of morbidity and mortality, thus providing an opportunity to improve fetal outcomes. Prospective longitudinal study conducted through the period from September 2011–July 2012, 125 women with normal pregnancy and uncomplicated fetal outcomes were recruited and subjected to Doppler velocimetry at different gestational ages, from 36 to 40 weeks. Of those, 15 women did not fulfill the protocol inclusion criteria and were not included. In the remaining 110 participants a follow up study of Fetal Doppler velocimetry of Ao and UA was performed at 36 – 40 weeks of gestation. Ao/UA RI: 1.48±0.26, 1.33±0.25, 1.37± 0.20, 1.28±0.07 and 1.39±0.45 respectively and the 95% confidence interval of the mean for five weeks 1.13-1.63. Ao/UA PI: 2.83±2.6, 1.94±0.82, 2.08±0.53, 1.81± 0.12 and 3.28±2.24 respectively. Ao/UA S/D: 2.14±0.72, 2.15±1.14, 1.75±0.61, 2.52±0.18 and 2.26±0.95. The data concluded that a nomogram of descending aorto-placental ratio Ao/UA, S/D, PI and RI of Iraqi obstetric population was established. -

Dept. Of Anatomy, SSMC. Tumkur.Karnataka.India Professor & HOD. Dept. Of Anatomy, SSMC. Tumkur.Karnataka.India Associate professor.Dept. Of Anatomy, SSMC. Tumkur.Karnataka.India Abstract:Variations in the branching pattern of abdominal aorta are quite common, knowledge of which is required to avoid complications during surgical interventions involving the posterior abdominal wall. Inferior Phrenic Arteries, the lateral aortic branches usually arise from Abdominal Aorta ,just above the level of celiac trunk. Occasionally they arise from a common aortic origin with celiac trunk, or from the celiac trunk itself or from the renal artery. This study describes the anomalous origin of this lateral or para aortic branches in the light of embryological and surgical basis. Knowledge of such variations has important clinical significance in abdominal operations like renal transplantation, laparoscopic surgery, and radiological procedures in the upper abdomen or invasive arterial procedures . Keywords: Abdominal Aorta, Celiac Trunk(Ct), Diaphragm, Inferior Phrenic Artery (Ipa), Retro Peritoneal, Renal Artery(Ra). I. Introduction The abdominal aorta begins from the level of 12th thoracic vertebra after passing through the Osseo aponeurotic hiatus of diaphragm. It courses downwards with Inferior vena cava to its right and terminates at the level of 4th lumbar vertebra by dividing in to two terminal branches. -

Aorta and the Vasculature of the Thorax
Aorta and the Vasculature of the Thorax Ali Fırat Esmer, MD Ankara University Faculty of Medicine Department of Anatomy THE AORTA After originating from left ventricle, it ascends for a short distance, arches backward and to the left side, descends within the thorax on the left side of the vertebral column It is divided for purposes of The aorta is the main arterial trunk description into: that delivers oxygenated blood from Ascending aorta the left ventricle of the heart to the Arch of the aorta and tissues of the body. Descending aorta (thoracic and abdominal aorta) Ascending Aorta The ascending aorta begins at the base of the left ventricle runs upward and forward at the level of the sternal angle, where it becomes continuous with the arch of the aorta it possesses three bulges, the sinuses of the aorta Branches Right coronary artery Left coronary artery ARCH OF THE AORTA The aortic arch is a continuation of the ascending aorta and begins at the level of the second sternocostal joint. • It arches superiorly, posteriorly and to the left before moving inferiorly. • The aortic arch ends at the level of the T4 vertebra / at level of sternal angle. Branches; Brachiocephalic artery (Innominate artery) Left common carotid artery Left subclavian artery It begins when the ascending aorta emerges from the pericardial sac and courses upward, backward, and to the left as it passes through the superior mediastinum, ending on the left side at vertebral level TIV/V. Extending as high as the midlevel of the manubrium of the sternum, the arch is initially anterior and finally lateral to the trachea.
