The liver document provides a summary of the anatomy and structures of the liver in 3 paragraphs or less:
The liver is the largest visceral organ located primarily in the right hypochondrium and epigastric region, extending into the left hypochondrium. It has 4-5 lobes and is connected to other structures by ligaments such as the falciform ligament. The liver receives blood from the portal vein and hepatic artery and excretes bile through the left and right hepatic ducts which join to form the common hepatic duct along with the cystic duct from the gallbladder. This forms the common bile duct which terminates at the ampulla of Vater in the duodenum.
The pancreas is an elongated gland that extends transversely across the posterior abdominal wall from the duodenum to the spleen. It has a head, neck, body, and tail. The head is flattened and occupies the concavity of the duodenum. The neck joins the head to the body. The triangular body extends to the left, crossing the median plane opposite L1. The tail passes between the layers of the lienorenal ligament to relate to the spleen. The main pancreatic duct drains the tail and passes towards the head, uniting with the common bile duct in the duodenum.
The document discusses the blood supply of the gut. It is divided into three parts: the foregut, midgut, and hindgut. The foregut receives its blood supply from the celiac trunk.

Remember, the kidneys play a crucial role in maintaining homeostasis by regulating fluid balance, electrolytes, and waste elimination. Ureter Anatomy
Overview
The ureters are bilateral, muscular, tubular structures responsible for transporting urine from the kidneys to the urinary bladder for storage and eventual excretion.
After blood filtration in the kidneys, the filtrate undergoes reabsorption and exudation along the convoluted tubules.
The urine then passes through the collecting tubules and enters the collecting ducts.
From the collecting ducts, it flows through the calyces into the renal pelvis, marking the beginning of the ureters.
Histology of Ureter
The lumen of each ureter is lined by a mucosal layer of urothelium (transitional epithelium).
The ureteral wall contains two muscular layers:
Longitudinal layer
Circular layer
In the lower segment of the ureters, an additional longitudinal layer is found proximal to the bladder.
Urine is propelled along the ureters by peristaltic motions initiated by pacemaker cells in the proximal renal pelvis.
Relations
Both ureters pass inferiorly over the abdominal surface of the psoas major muscle.
The right ureter travels posterior to the duodenum and is crossed by branches of the superior mesenteric vessels.
The left ureter is also posterior to the psoas major and is crossed by branches of the inferior mesenteric vessels.

The liver is the largest solid organ in the body, located in the upper right quadrant of the abdomen. It has five surfaces and weighs approximately 1600g in males and 1300g in females. The liver performs many critical functions, including metabolizing nutrients, producing bile, and filtering blood from the digestive tract. It is supplied by the hepatic artery and portal vein and drains into the inferior vena cava. The liver has two lobes, is divided into segments, and contains lobules that are made up of hepatocytes and sinusoids. Common disorders of the liver include hepatitis, cirrhosis, and jaundice.
*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 urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine. Each kidney is bean-shaped and located retroperitoneally on either side of the spine. The kidneys contain an outer cortex and inner medulla and are supplied by the renal arteries. The urine produced by the kidneys drains through the ureters into the urinary bladder for storage and then exits through the urethra.
The kidneys are bean-shaped organs located retroperitoneally between vertebrae T12 and L3. Each kidney has an outer renal cortex and inner renal medulla divided into renal pyramids. The kidneys are supplied by renal arteries and drained by renal veins and lymphatics. Urine drains from the kidneys through the ureters into the bladder. The ureters have several points of narrowing as they course retroperitoneally from the kidneys to the bladder.
This document provides an overview of the anatomy of the abdomen, including surface anatomy, abdominal quadrants, muscles of the anterior and posterior abdominal walls, the abdominopelvic cavity, peritoneum, divisions of the peritoneal cavity, and blood supply. Key points include: the abdomen is divided into 9 regions within 4 quadrants; the anterior abdominal wall muscles include the rectus abdominis, internal and external obliques, and transversus abdominis; the peritoneum lines the abdominal cavity and organs; and the peritoneal cavity is divided into supracolic, infracolic, and pelvic compartments.

The urinary system consists of two kidneys, two ureters, a urinary bladder, and a urethra. The kidneys filter waste from the blood to produce urine. The ureters carry urine from the kidneys to the bladder. The bladder stores urine until urination, at which point urine passes through the urethra and out of the body. Together these structures work to regulate fluid balance and remove waste via urine production and storage.
The kidneys filter waste from the blood to produce urine, which then travels down the ureters into the urinary bladder. The bladder stores urine until urination, when it is expelled through the urethra. The kidneys and urinary system work together to remove waste from the body and regulate fluid balance and blood pressure.
The kidneys are retroperitoneal paired organs located on the posterior abdominal wall. Each kidney has an outer renal cortex and inner renal medulla divided into renal pyramids. The kidneys receive blood supply from the renal arteries which branch into segmental arteries then further branch into interlobar arteries and arcuate arteries. Venous drainage occurs through interlobular veins, arcuate veins, and interlobar veins which drain into the renal veins. The kidneys are surrounded by perirenal fat and renal fascia and have anterior relations to other abdominal organs and posterior relations to the diaphragm and vertebral column.
The document describes the anatomy of the abdominal regions, abdominal wall and cavity, and gastrointestinal organs including the esophagus, stomach, and small intestine. It divides the abdomen into 9 regions based on 4 reference planes and lists the organs contained within each region. It details the layers of the abdominal wall and peritoneal cavity. It provides information on the esophagus, stomach sections and functions, and sections of the small intestine including the duodenum.

Assessment and Planning in Educational technology.pptxKavitha Krishnan
In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
