Branches of thoracic & abdominal aorta
The document summarizes the branches of the thoracic and abdominal aorta in humans. It describes the visceral and parietal branches of the thoracic aorta that supply the thoracic walls, viscera, and spinal cord. It then discusses the various visceral branches of the abdominal aorta including the celiac artery, superior mesenteric artery, inferior mesenteric artery, and renal arteries. It concludes by outlining the branches of the internal iliac artery including the internal pudendal, umbilical, and lateral sacral arteries.
Development of heart iv
1. The document describes the development of primitive veins including the vitelline, umbilical, and cardinal veins.
2. It explains how the umbilical veins contribute to formation of the portal vein and ductus venosus. The vitelline veins form anastomoses and tributaries that contribute to the hepatic vasculature.
3. The cardinal veins give rise to major veins including the subclavian, inferior vena cava, and azygos system. Variations in regression of veins can result in anomalies such as double inferior vena cava.
The chambers of heart
The human heart consists of 4 chambers - two upper atria and two lower ventricles separated by muscular walls. The left atrium opens to the left ventricle and right atrium to the right ventricle, and valves between the chambers ensure blood flows only in one direction from the atria to the ventricles. Arteries carry blood away from the heart while veins bring blood back to the heart, and valves in the arteries also prevent backflow into the heart.
Celiaco Mesenteric Trunk - A Case Report
Variations in the branching pattern of abdominal aorta are quite common, knowledge of which is
required to avoid complications during surgical interventions involving GIT and posterior abdominal wall.
Celiac trunk & Superior mesenteric Arteries, the ventral aortic branches usually arise independently from
Abdominal Aorta , one just above the other. Occasionally they arise from a common aortic origin. This study
describes the anomalous origin of these ventral or pre aortic branches of abdominal aorta in the light of
embryological and surgical basis. Knowledge of such variations has important clinical significance in
abdominal operations like Small and large bowel surgeries , laparoscopic surgery, and radiological
procedures in the upper abdomen or invasive arterial procedures.
Aorta

Anatomy Of The Heart
The heart is a cone-shaped organ located in the chest cavity between the lungs. It is surrounded by fluid-filled sac called the pericardium. The heart has four chambers - two upper atria that receive blood and two lower ventricles that pump blood out. Blood flows through valves from the atria to ventricles and then out arteries or pulmonary artery. The heart's wall has three layers - outer epicardium, middle muscular myocardium, and inner endocardium. The heart continuously contracts and relaxes in a cardiac cycle of diastole and systole to pump blood through the body.
Structure Of A Heart
The heart is a four-chambered muscular organ that pumps blood through the body using rhythmic contractions. It has four chambers - the right and left atria which collect blood, and the right and left ventricles which pump blood out of the heart. The heart beats between 60-80 times per minute, pumping deoxygenated blood to the lungs and oxygenated blood to the rest of the body. Valves between the chambers allow blood to flow in only one direction to prevent mixing of oxygenated and deoxygenated blood.
Surgery 5th year, 9th, 10th &11th lectures (Dr. Ahmed Al-Azzawi)
Cardiac surgery involves three types of operations - extra-cardiac, closed intra-cardiac, and open cardiac operations. Extra-cardiac operations are done on vessels or structures outside the heart. Closed intra-cardiac operations are done blindly through an incision in the heart wall. Open cardiac operations allow the surgeon to operate directly on the open and motionless heart with the use of cardiopulmonary bypass to manage circulation. The history and anatomy of the heart as well as details of cardiac valves and vessels are provided for context.

Circulatory anatomy
The circulatory system consists of two circuits - systemic and pulmonary. The vascular system includes arteries, which carry blood away from the heart, and veins, which carry blood back to the heart. The aorta branches into smaller arteries that supply different regions of the body with blood. The ascending aorta branches into the right and left coronary arteries to supply the heart. The arch of the aorta branches into arteries that supply the head and neck. The abdominal aorta branches to supply the abdomen, pelvis and lower limbs. Veins collect deoxygenated blood and return it to the right atrium or inferior vena cava which returns to the heart. The circulatory system efficiently transports blood, nutrients and gases throughout the entire
Development of heart
1. The heart develops from mesoderm in the cardiogenic area as two endothelial heart tubes that fuse to form a single tube. This tube undergoes looping to form the four chambers.
2. The heart chambers develop from the bulbus cordis, primitive ventricle, primitive atrium, and sinus venosus portions of the heart tube. Septa form to divide the atria and ventricles. Valves develop from endocardial cushions.
3. Congenital heart defects can occur due to abnormal septation, outflow tract defects, or abnormal looping and siting of the heart. Common defects include atrial and ventricular septal defects, tetralogy of Fallot, and

Semilunar valves are located at the pulmonary trunk and aorta while atrioventricular valves are located between the atria and
Blood supply of the brain
The brain receives its blood supply from two internal carotid arteries and two vertebral arteries. These vessels anastomose at the base of the brain to form the Circle of Willis. The internal carotid artery gives off branches that supply the anterior circulation, including the anterior cerebral artery and middle cerebral artery. The vertebral arteries join to form the basilar artery, which supplies the posterior circulation via the posterior cerebral artery. Venous drainage follows complex patterns into dural sinuses and cerebral veins before emptying into the internal jugular veins.

907472 renal-autoregulation
This document discusses new perspectives on the roles of renal autoregulation mechanisms in protecting the kidney from hypertension and regulating renal function. It argues that the primary role of the myogenic response is to protect the kidney by responding to oscillating systolic blood pressure and limiting pressure transmission. Precise moment-to-moment regulation of renal hemodynamics is not required for volume homeostasis. While autoregulation and tubuloglomerular feedback act together to stabilize renal function, their roles in protection versus regulation may differ, and interactions between the mechanisms are complex.
