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.
Stomach anatomy
The stomach is a J-shaped organ located in the upper left portion of the abdominal cavity. It continues the mechanical and chemical digestion of food and empties into the small intestine. The stomach has four regions - the cardia, fundus, body, and pyloric part. It functions to digest food, produce acid, act as a reservoir, and slow food entering the intestines. The stomach receives blood supply from the left and right gastric arteries and drains venous blood into the portal system. Lymph from the stomach drains into superior, suprapyloric, pancreaticosplenic, and subpyloric lymph nodes. The vagus nerve provides parasympathetic innervation while the splanchnic nerve

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.
Development of stomach
The stomach develops from the foregut as a simple tubular structure that enlarges dorsally through differential growth. It rotates along two axes, determining its final position in the left hypochondrium. The dorsal mesogastrium suspends the stomach and later forms the greater omentum. The duodenum develops from the foregut and midgut, forming a C-shaped loop that rotates to the right as the stomach rotates left. Both become retroperitoneal as their mesenteries fuse with the posterior abdominal wall.

Portal vein & portocaval anastomosis
The portal vein collects blood from the abdominal organs and conveys it to the liver. It breaks up into sinusoids in the liver, where the blood mixes with hepatic arterial blood. When the portal vein is obstructed, collateral circulation develops through portosystemic communications, most notably esophageal varices, caput medusae around the umbilicus, and hemorrhoids in the anal canal, which are clinical signs of portal hypertension.
Small intestine and large intestine- BPT.pptx
The small intestine extends from the stomach to the large intestine. It is further divided into the duodenum, jejunum, and ileum. The small intestine absorbs nutrients through fingerlike projections called villi lined with absorptive enterocytes. Peristalsis and segmentation contractions mix and propel intestinal contents. The large intestine extends from the ileum to the anus and absorbs water and forms feces for excretion. Diseases include obstruction, malabsorption, and abnormalities in defecation like constipation and diarrhea.
Cardiac skeleton
The fibrous skeleton of the heart:
1. Lies between the atria and ventricles.
2. Is composed of dense connective tissue that forms fibrous rings around the four heart valves.
3. Acts as an electrical insulator to prevent direct spread of electrical impulses from the atria to the ventricles, ensuring impulses pass through the bundle of His for coordinated ventricular contraction.

The body is then divided into three sections: the fundus, body, and neck. The cystic duct connects the gallbladder to the biliary tree. Bile duct anatomy is also described, including the common hepatic duct and common bile duct. The document concludes with some interesting facts about cultural associations with the gallbladder and its role in traditional Chinese medicine.
Anatomy of the heart
The heart is pyramidal in shape with an apex pointing leftward and downward. It has four chambers - two atria which receive blood and two ventricles which pump blood. The right atrium receives deoxygenated blood from the body and pumps it to the right ventricle to be sent to the lungs. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle to be sent to the body. Blood flows through the heart via the tricuspid, bicuspid/mitral, pulmonary and aortic valves. The heart's conduction system coordinates contractions and is composed of the sinoatrial node, atrioventricular node and bundle of His.
Gi physiology
The document describes the key functions of the gastrointestinal system, including ingestion, propulsion, digestion, absorption, and elimination. It details the processes of mechanical and chemical digestion which break down food throughout the digestive tract. Absorption of nutrients occurs in the small intestine, while the liver and pancreas produce bile and enzymes to further break down fat. The colon absorbs water from waste before it is eliminated.
Liver pancreas
The document provides information about the liver, gallbladder, and pancreas. It discusses the morphology and functions of each organ. The liver has two lobes and is surrounded by Glisson's capsule.

Anatomy of kidney By M.Adil
The kidneys are two bean-shaped organs located retroperitoneally in the abdomen on either side of the spine. Each kidney is approximately 11cm long, 6cm wide, and 3cm thick. The kidneys filter waste from the blood and regulate fluid and electrolyte balance. Internally, each kidney contains an outer cortical layer and inner medullary pyramids separated by renal columns. Blood enters via the renal artery and drains via the renal vein, while urine exits through the ureter. The kidneys are surrounded by protective layers including the renal capsule, adipose capsule, and renal fascia. Coronavirus can directly damage the kidneys by binding to ACE2 receptors found in renal cells.
Anatomy of liver
The liver is the largest internal organ located in the right upper quadrant of the abdomen. It has two surfaces - the diaphragmatic surface and visceral surface. The liver is divided into 8 segments based on the Couinaud classification which describes the functional anatomy and vascular supply. This allows for resection of individual segments without damaging other segments. The segments are delineated by the hepatic veins and portal scissurae into right, left, caudate and quadrate lobes.

Cardiac output & factors affecting it.
“Cardiac output refers to the volume of blood pumped out per ventricle per minute.”
Cardiac output is the function of heart rate and stroke volume.
STROKE VOLUME:
The amount of blood pumped by the left ventricle in one compression is called the stroke volume.
Heart Rate
The cardiac output increases with the increase in heart rate.
Peritoneum Dr. Mehul Tandel
The peritoneum is a serous membrane that lines the abdominal cavity and covers organs within. It has parietal and visceral layers. Folds of peritoneum like the mesentery, omenta, and ligaments suspend organs and allow passage of structures. The greater and lesser sacs are potential spaces within the peritoneal cavity. The lesser sac is posterior to the stomach and separated from the greater sac by the epiploic foramen. Folds like the mesentery provide blood supply to the intestines and omenta can seal infections and absorb fluid.
Cardiac cycle
The cardiac cycle refers to the repeating sequence of events in the heart from one heartbeat to the next. It consists of systole, the contraction phase, followed by diastole, the relaxation phase. Systole includes isovolumic contraction, rapid ejection, and slow ejection as the ventricles contract and pump blood out. Diastole includes isovolumic relaxation, rapid filling, slow filling, and atrial systole as the ventricles relax and fill with blood. Key measurements of heart function include end-diastolic volume, end-systolic volume, stroke volume, and ejection fraction. The aortic and pulmonary valves close more forcefully than the atrioventricular valves.
Hepatobilliary system
The liver is the largest visceral organ located in the upper right quadrant of the abdominal cavity. It performs over 200 essential functions including nutrient storage, breakdown of red blood cells, bile secretion, and synthesis of proteins and cholesterol. The liver receives blood from the hepatic portal vein and hepatic artery and drains into the hepatic veins. It is divided into four lobes and has both a diaphragmatic and visceral surface. The gallbladder stores and concentrates bile produced by the liver. Cirrhosis is a condition where the liver develops scar tissue due to chronic damage.
Digestive system anatomy clinic
The digestive system contains the digestive tract and associated organs. The digestive tract begins at the mouth and includes the esophagus, stomach, small intestine, and large intestine. The major associated organs are the teeth, tongue, salivary glands, liver, gallbladder and pancreas. The digestive system breaks down food into smaller molecules that can be absorbed and used by the body.

The document concludes by covering combining forms, abbreviations, diagnostic and laboratory terms related to the digestive system.
The Digestive System
The document summarizes the key organs and functions of the human digestive system. It describes the seven main organs - mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. It explains that the digestive system breaks down food, absorbs nutrients for energy and nutrition, and eliminates waste from the body.
LIVER AND GALL BLADDER.pptx DIGESTIVE SYSTEM
The liver and gallbladder document discusses:
1. The liver is the largest gland in the body and performs many vital metabolic functions like metabolizing nutrients, storing vitamins and minerals, and secreting bile.
2. Bile, produced by the liver, aids in digestion and absorption of fats. It is stored and concentrated in the gallbladder before being released into the small intestine.
3. Gallstones form when there is a precipitation of cholesterol, calcium ions, or bile pigments in the gallbladder mucosa. Risk factors include reduced bile salts, excess cholesterol, or damage to the gallbladder epithelium.

The document provides information about the digestive system, including its main organs and their functions. It discusses the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, pancreas and salivary glands. It describes how each organ aids in ingestion, digestion, absorption and elimination of food. The digestive system breaks down food, extracts nutrients and water, and expels waste to sustain the body.
The digestive system
The document summarizes the key components and functions of the digestive system. It describes the digestive tract as a long twisting tube starting at the mouth and ending at the anus. It then discusses four main organs - the liver, stomach, gallbladder, and pancreas. The liver produces bile and filters toxins from the blood. The stomach stores, breaks down, and mixes food before slowly emptying it into the small intestine. The gallbladder stores and releases bile to aid digestion. The pancreas produces hormones like insulin that regulate blood sugar and enzymes that help break down food.

DIGESTIVE SYSTEM.pptx
The digestive system breaks down food into nutrients that the body can use. It begins with the mouth and ends with the anus. Major organs include the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. Food is ingested, digested, absorbed in the small intestine, and waste is excreted. Digestion involves breaking down food into smaller molecules like amino acids and monosaccharides using enzymes from the saliva, stomach acid, bile, and pancreatic juice. The small intestine absorbs nutrients into the bloodstream through villi while the large intestine absorbs water before excreting waste.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
