Thoracic aorta
The thoracic aorta begins where the aortic arch ends at the fourth thoracic vertebrae and extends down to the diaphragm. It supplies blood to the thoracic cavity and has several important branches including the bronchial arteries which supply the lungs, esophageal arteries which supply the esophagus, and posterior intercostal arteries which supply the spaces between the ribs. The thoracic aorta also gives off mediastinal and pericardial branches before passing through the diaphragm and becoming the abdominal aorta.
Abdominal aorta
The abdominal aorta originates at the T12 vertebrae and runs downward in front of the lumbar vertebrae, terminating at the L4 vertebrae by dividing into the common iliac arteries. It gives off several unpaired branches including the celiac trunk, superior mesenteric artery, and inferior mesenteric artery. It also provides paired arteries such as the inferior phrenic, suprarenal, renal, gonadal, lumbar, and common iliac arteries that supply the abdominal organs and structures.
Superior vena cava
The superior vena cava receives deoxygenated blood from the upper body and delivers it to the right atrium. It is formed by the merging of the brachiocephalic veins and descends through the thoracic region into the right atrium. Its tributaries include the brachiocephalic veins, azygos vein, and intercostal veins. Obstruction of the superior vena cava can result in the development of collateral pathways through the azygos vein or between tributaries of the superior and inferior vena cavae.

Liver anatomy
The document describes the anatomy and segmentation of the liver. It notes that the liver is divided into eight functionally independent segments, with each segment having its own vascular inflow, outflow and biliary drainage. It describes Couinaud's division of the liver into a functional left and right liver divided by Cantlie's line, which runs from the middle of the gallbladder fossa to the inferior vena cava. Because of this segmentation, individual segments can be surgically resected without damaging remaining segments.
arch of aorta
The arch of the aorta begins at the level of the sternal angle and arches over the root of the left lung in the superior mediastinum. It begins as the continuation of the ascending aorta and passes up, back, and left before turning backwards and downwards to become the descending aorta at the level of T4. It has anterior relations to the left lung and pleura and posterior relations to the trachea, esophagus, and thoracic duct. Its branches include the brachiocephalic trunk, left common carotid artery, and left subclavian artery.
Anatomy of the stomach
The stomach is a J-shaped organ located in the upper abdomen between the esophagus and small intestine. It acts as a reservoir for food and aids in the digestion of carbohydrates, proteins, and fats. The stomach has two openings - the cardiac orifice where it connects to the esophagus and the pyloric orifice where it connects to the small intestine. It is divided into sections including the fundus, body, antrum, and pyloric canal. The stomach receives blood supply from branches of the celiac artery and drains into gastric lymph nodes. It is innervated by both the sympathetic and parasympathetic nervous systems to aid in digestion. Diseases that commonly
anatomy of liver
The liver is the largest gland in the human body, weighing approximately 1500 grams. It performs many important functions like absorbing nutrients from the gastrointestinal tract, storing glycogen, and secreting bile. The liver has two lobes - the right lobe, which is the largest, and the left lobe. It is situated in the right upper quadrant of the abdomen and has two surfaces - the diaphragmatic surface and the visceral surface. The liver receives blood from the hepatic portal vein and hepatic artery and is supported by various ligaments.
anatomy of spleen
The spleen is a hematopoietic organ located in the left upper quadrant of the abdomen. It filters blood and fights infections. The spleen develops from mesenchymal cells in the dorsal mesogastrium and has dimensions of approximately 12x7x3 cm and a weight of 150 grams in adults. It receives a blood supply from the splenic artery and drains into the portal vein system. The spleen can be surgically removed (splenectomy) in cases of trauma or certain blood disorders.
Liver
The liver is the largest gland in the body, located in the upper right quadrant of the abdomen under the diaphragm and within the rib cage. It has four lobes - two major lobes and two minor lobes - and ducts that carry bile from the liver to the gallbladder and join the pancreatic duct. The liver is made up of lobules containing hepatocytes that radiate outward from a central vein and produce and secrete bile. Blood flows to the liver through the hepatic portal vein and supplies the liver with nutrients and oxygen. The liver performs many important metabolic functions like synthesizing and breaking down substances, and excreting waste from the bloodstream into bile.
Anatomy of stomach
The document summarizes the anatomy and features of the stomach. It describes the stomach's location in the upper left part of the abdomen. It has a J-shape and varies in size, holding 1.5-2 liters in adults. The stomach functions to form a reservoir for food, mix food with gastric juices to form chyme, and control the rate at which chyme enters the small intestine to allow for proper digestion.
Pericardium and heart
The pericardium has two layers - the fibrous pericardium and serous pericardium. The fibrous pericardium is a dense connective tissue that protects the heart. The serous pericardium contains two layers that lubricate the heart and prevent friction. It also contains the pericardial cavity filled with fluid. Too much fluid in the cavity can cause compression of the heart.
Extrahepatic Biliary Apparatus
The extrahepatic biliary apparatus consists of the right and left hepatic ducts, common hepatic duct, gallbladder, cystic duct, and bile duct. The hepatic ducts emerge from the liver and join to form the common hepatic duct, which then joins with the cystic duct from the gallbladder to form the bile duct. The gallbladder is a reservoir for bile located in the liver that concentrates and stores bile before releasing it through the cystic duct into the bile duct for transport to the duodenum. The bile duct courses through the liver and pancreas, joining with the pancreatic duct before entering the duodenum.
2. External features of the heart
The heart is a hollow muscular organ located in the mediastinum. It has 4 chambers - right atrium, left atrium, right ventricle, and left ventricle. The heart is divided by septa into these chambers. The heart has surfaces including the sternocostal surface and diaphragmatic surface. It receives blood supply from the right and left coronary arteries. Deoxygenated blood returns to the heart via the coronary sinus and associated veins which drain into the right atrium.

2) Openings of the stomach include the cardiac orifice where the esophagus enters and the pyloric orifice where the stomach meets the duodenum.
3) The stomach is divided into four regions - the fundus, body, pyloric antrum, and pyloric canal. Glands in the fundus and body secrete digestive enzymes and hydrochloric acid
Development of stomach
The stomach develops from the foregut during the fourth week of embryonic development. It undergoes two rotations along longitudinal and anteroposterior axes to reach its final adult position. The stomach receives its blood supply from branches of the celiac trunk and develops a complex mucosal and submucosal vascular network. Rare congenital anomalies can affect the shape and rotation of the stomach. Gastric volvulus is a serious condition where the stomach twists around its axes, potentially causing obstruction or ischemia.
liver.pptx
*Features*
•The liver is a large and solid gland situated in the right upper quadrant of the abdominal cavity. In the living subject, the liver is reddish brown in colour, soft in consistency, and very friable. It weighs about 1600 g in males and about 1300 g in females.
*Location*
The liver occupies the whole of the right hypo chondrium, the greater part of the epigastrium, and extends into the left hypochondrium reaching up to the left lateral line. From the above, it will be obvious that most of the liver is covered by ribs and costal cartilages, except in the upper part of the epigastrium where it is in contact with the anterior abdominal wall.
The liver is the largest gland in the body. It secretes.
bile and performs various other metabolic functions. The liver is also called the 'hepar' from which we have the adjective 'hepatic' applied to many structures connected with the organ.
*External Features*
The liver is wedge-shaped. It resembles a four-sided pyramid laid on one side.
*Surfaces*
It has five surfaces. These are:
1 Anterior, 2 Posterior,3 Superior,4 Inferior, and 5 Right.
Out of these, the inferior surface is well defined because it is demarcated, anteriorly, by a sharp inferior border. The other surfaces are more or less continuous with each other and are imperfectly separated from one another by ill-defined, rounded borders.
*Prominent Border*
The inferior border is sharp anteriorly where it separates the anterior surface from the inferior surface. It is somewhat rounded laterally where it separates the right surface from the inferior surface. The sharp anterior part is marked by:
a. An interlobar notch or the notch for the ligamentum teres. b. A cystic notch for the fundus of the gallbladder In the epigastrium, the inferior border extends from the left 8th costal cartilage to the right 9th costal cartilage.
*Lobes*
The liver is divided into right and left lobes by the attachment of the falciform ligament anteriorly and superiorly; by the fissure for the ligamentum teres inferiorly; and by the fissure for the ligamentum venosum posteriorly.
The right lobe is much larger than the left lobe, and forms five-sixths of the liver. It contributes to all the five surfaces of the liver, and presents the caudate and quadrate lobes.
The caudate lobe is situated on the posterior surface. It is bounded on the right by the groove for the inferior vena cava, on the left by the fissure for the ligamentum yenosum, and inferiorly by the porta hepatis. Above, it is continuous with the superior surface. Below and to the right, just behind the porta hepatis, it is connected to the right lobe of the liver by the caudate process .Below and to the left, it presents a small rounded elevation called the papillary process.
The quadrate lobe is situated on the inferior surface, and is rectangular in shape. It is bounded anteriorly by the inferior border, posteriorly by the porta hepatis, on the right by the fossa for the hepatic ducts.

The pancreas is a J-shaped gland located in the retroperitoneal space behind the stomach. It has four parts - a head, neck, body, and tail. The head lies in the concavity of the duodenum. The pancreatic duct drains the exocrine secretions into the duodenum by joining the bile duct. The main arterial blood supply comes from branches of the splenic artery and superior pancreaticoduodenal artery. Carcinoma commonly occurs in the head of the pancreas and can cause jaundice by compressing the bile duct.

Esophagus stomach-dr.gosai
The document provides information on the esophagus and stomach. It discusses the anatomy of the lower esophagus, including its blood supply and clinical aspects like esophageal constrictions. It then covers the position, shape, divisions, interior structure, blood supply, nerve supply, and clinical applications of the stomach, such as gastric ulcer, carcinoma, and gastroscopy. Key points include the esophagus passing through the diaphragm and having portosystemic anastomoses, and the stomach's J-shape and divisions into cardiac, fundic, and pyloric portions supplied by branches of the celiac artery.
Stomach
The stomach is a J-shaped muscular sac located in the upper abdomen between the esophagus and small intestine. It is divided into four regions - the cardia, fundus, body, and pyloric part. The stomach has two openings: the gastroesophageal opening connects to the esophagus, and the pyloric opening connects to the duodenum. Blood supply comes from the left and right gastric arteries as well as branches from the splenic and hepatic arteries. Lymphatic drainage and innervation is provided mainly by the left and right vagus nerves.
Isha zulfiqar
The abdomen contains the major digestive organs including the stomach, small and large intestines, liver, gallbladder and pancreas. These organs are held loosely in place by connecting tissues that allow movement. The abdomen also houses the kidneys and spleen. Important blood vessels such as the aorta and vena cava pass through the abdomen. The front of the abdomen is protected by fascia and muscles, while the back is protected by back muscles and the spine. On the right side are located the liver, right kidney, gallbladder and parts of the intestines while the left side contains the heart, left lung, pancreas, spleen and left kidney. The ureters begin at the kidneys and travel down inside the abdominal

suprarenal gland situated just above the renal system
The adrenal glands are located retroperitoneally on the upper poles of each kidney. Each gland has an inner true capsule and outer false capsule. The right gland is pyramidal in shape while the left is semilunar. They consist of an outer cortex and inner medulla. The cortex secretes mineralocorticoids, glucocorticoids and sex hormones. The medulla secretes epinephrine and norepinephrine. The glands receive their blood supply from superior, middle and inferior suprarenal arteries and drain into the inferior vena cava or left renal vein.

EFFECT OF CAFFEINE IN CARDIOVASCULAR HEALTH- A DOUBLE.pptx
Caffeine (1,3,7-trimethylxanthine) is an alkaloid which act as a central nervous system (CNS) stimulant, that is naturally found in many different plants such as coffee beans, cocoa beans, tea leaves, guarana berries and the kola nut. It can also be artificially synthesized for use as a food additive, in dietary supplements, even medications in over the counter or pharmaceutical preparations where synthetic caffeine is identical to intrinsic or plant-derived caffeine. Many studies says that intake of caffeine in the safe dose range has been associated with a reduction in the risk of chronic diseases, especially cardiovascular disease. There is evidence that caffeine intake has both protective and negative effects on cardiovascular diseases, so we named caffeine as a double edge sword. In this review, we had explained about safe dose range of caffeine, positive and negative effects of caffeine in cardiovascular health.

CENTRAL VENOUS PRESSURE.pptx
Central venous pressure is defined as the measure of pressure in the vena cava, can be used as an estimation of preload and right atrial pressure.
CVP is also defined as pressure of blood returning to or filling in the Right atrium (Filling pressure).
Central venous pressure is often used as an assessment of hemodynamic status, particularly in the intensive care unit.
Pressure in IVC and SVC = Pressure in Right Atrium
The central venous pressure can be measured using a central venous catheter advanced via the internal jugular vein and placed in the superior vena cava near the right atrium.
A normal central venous pressure is between 8 to 12 mmHg.

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
