Heart
The document discusses the structure and function of the human heart. It describes the heart's location in the thoracic cavity and its size. It details the internal chambers and valves of the heart, including the atria, ventricles, tricuspid, bicuspid, pulmonary, and aortic valves. It explains the heart's role in circulating blood through the body via the circulatory system, and the cardiac cycle of systole and diastole that pump blood through contraction and relaxation of the heart muscles.
Human Heart
The heart is a muscular organ that pumps blood through the circulatory system. It is located in the thoracic cavity behind the sternum. The human heart has four chambers - two upper atria and two lower ventricles. The right side contains deoxygenated blood while the left side contains oxygenated blood. Factors like obesity, high blood pressure, cholesterol, diet, exercise and overall well-being affect heart health and risk of diseases.
Ass
The human heart is roughly the size of a large fist and weighs between 9 and 12 ounces. It has four chambers - two upper atria and two lower ventricles - separated by a muscular wall. The heart circulates blood through the pulmonary and systemic circuits, with oxygenated blood entering the left atrium and deoxygenated blood entering the right atrium. Electrical pacemaker cells cause the heart to contract in five stages in each heartbeat cycle to pump blood throughout the body, beating around 100,000 times per day.
ANATOMY AND PHYSIOLOGY OF HEART
The heart is a muscular organ that pumps blood through the circulatory system. It has four chambers - two upper atria and two lower ventricles. The right side receives deoxygenated blood and pumps it to the lungs, while the left side receives oxygenated blood and pumps it out to the body. Valves prevent backflow between chambers. The heart is surrounded by membranes and layers including the pericardium. It is located in the chest cavity and has distinct surfaces and structures that allow it to efficiently circulate blood throughout the body.
Human heart presentation
The heart is a conical shaped, muscular organ that is located in the chest cavity between the lungs, tilted slightly to the left. It is roughly 12cm long, 9cm broad and weighs 300 grams in adult humans. The heart is covered by a double-membrane sac called the pericardium, with fluid between the heart and pericardium that protects the heart.
System by RESHMA RILLISON RJ
The small intestine is coiled and folded within the abdominal cavity, causing food to move slowly through it. Its inner surface contains many villi that increase the surface area for nutrient absorption. Blood contains red blood cells, white blood cells, and platelets suspended in plasma and flows continuously throughout the body to transport materials and maintain homeostasis. When blood reaches tissues through capillaries, some plasma oozes into interstitial spaces where it becomes lymph and returns to the heart through lymph vessels without red blood cells or platelets. The circulatory system consists of the heart, blood, and blood vessels, with the heart pumping blood throughout the body in a double circulation through arteries and veins. The human heart has four chambers separated by valves that
Mediastinum 1
The mediastinum is the central partition of the thoracic cavity that contains structures like the heart, trachea, esophagus and major blood vessels. It is divided into superior, anterior, posterior and middle mediastinum. The superior mediastinum contains structures like the thymus gland, brachiocephalic veins, superior vena cava, arch of the aorta and its branches, trachea, esophagus, phrenic and vagus nerves. It is bounded superiorly by the thoracic inlet and inferiorly by the plane between T4 and T5 vertebrae. The structures pass through the mediastinum and provide blood supply and innervation to the thoracic organs.
Anatomy of heart presentation
The heart is a hollow muscular organ located in the middle mediastinum. It has four chambers - right and left atria and right and left ventricles. The heart is surrounded by membranes including the pericardium, myocardium and endocardium. Blood flows from the right atrium to right ventricle through the tricuspid valve, then to the lungs through the pulmonary semilunar valve. Oxygenated blood returns to the left atrium through pulmonary veins and flows to the left ventricle through the mitral valve and out the aortic semilunar valve to the rest of the body. The heart receives its blood supply from the left and right coronary arteries.

The Complete Reference to Human Heart
This document provides an overview of the cardiovascular system and heart structure and function. It contains 3 key points:
1. It describes the location of the heart in the chest, its layers (epicardium, myocardium, endocardium), chambers (right and left atria and ventricles), and valves (tricuspid, bicuspid, pulmonary, aortic).
2. It explains the conduction system that generates electrical signals to coordinate heart contractions, including the sinoatrial node, atrioventricular node, and Purkinje fibers.
3. It outlines the flow of blood through the heart and major blood vessels, including the coronary arteries and veins that supply the heart muscle itself
The cardiovascular system
This document provides an overview of the circulatory system, including its components and functions. It describes that blood is composed of plasma, proteins, formed elements, and transports oxygen, nutrients, and waste. It also summarizes the structures and roles of the heart, blood vessels (arteries, veins, capillaries), and different types of circulation (systemic, pulmonary, coronary, hepatic portal).
Mediastinum and heart position
The mediastinum is divided into superior, inferior, and middle sections. The middle mediastinum contains the heart, which is surrounded by the pericardium. The heart is cone-shaped with its apex pointing downward and to the left. Its surface can be delineated between the upper border of the third right costal cartilage superiorly, the middle of the right sixth costal cartilage laterally, the apex in the left fifth intercostal space midclavicularly, and the inferior border of the left second costal cartilage inferiorly.
Circulatory system
The circulatory system brings nutrients, oxygen, and hormones to tissues via two circuits: the cardiovascular system uses blood and the lymph vascular system uses lymph. The cardiovascular system consists of pulmonary and systemic circulation loops. The heart is the hollow muscular pump located in the chest that circulates blood through four chambers and two atria that receive blood and two ventricles that pump blood into the arteries. The lymph vascular system consists of a network of lymphatic capillaries and vessels that collect lymph from tissues and return it to the cardiovascular system.
Anatomy Of The Heart
The heart is a hollow muscular organ responsible for pumping blood through the body. It is enclosed in a sac called the pericardium and located in the mediastinum cavity in the center of the chest. The right side of the heart collects deoxygenated blood from the body and pumps it to the lungs, while the left side collects oxygenated blood from the lungs and pumps it out to the body. The heart's rhythm is controlled by electrical signals that cause the muscles to contract, originating from a pacemaker in the right atrium and traveling through conduction pathways.
HEART PRESENTATION

Dear Students/Parents
We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.
Committed to excellence...
With best wishes.

histology of Cardio vascular system 1
The cardiovascular system consists of the heart, arteries, arterioles, capillaries, venules and veins. The heart wall has three layers - the inner endocardium, middle myocardium and outer epicardium. The myocardium contains cardiac muscle fibers. Arteries have three layers - the inner intima containing endothelium, middle media containing smooth muscle and outer adventitia containing connective tissue. Elastic arteries have fenestrated elastic sheets and few smooth muscle fibers, while muscular arteries have more smooth muscle and less elastic sheets. Arterioles have a thin intima, thin media of 1-5 smooth muscle cell layers, and thin adventitia merging with surrounding tissue.
Anatomy of heart
The heart is a hollow muscular pump located in the chest cavity. It pumps blood through the circulatory system around the body. The left side pumps oxygenated blood through the arteries while the right side pumps deoxygenated blood to the lungs. On average, the heart beats over 2.5 billion times in a lifetime, pumping over 5,000 liters of blood per year. The heart is protected by membranes and surrounded by fluid within the pericardium. It has four chambers - two upper atria which receive blood and two lower ventricles which pump blood out. Blood flows through the heart via valves which ensure one-way flow.
Cardiovascular system
The cardiovascular system includes the heart and blood vessels. The heart has four chambers and pumps blood through two circuits. The systemic circulation pumps oxygenated blood from the left ventricle through arteries and returns deoxygenated blood to the right atrium via veins. The pulmonary circulation pumps deoxygenated blood from the right ventricle to the lungs through pulmonary arteries, where it becomes oxygenated and returns to the left atrium via pulmonary veins. The heart wall has three layers and four valves regulate blood flow. The conducting system uses specialized cardiac muscle fibers to generate and conduct electrical signals to coordinate heart contractions.

Basic Cardiovascular System Anatomy .pptx
The document provides an overview of the anatomy of the cardiovascular system. It describes the location and structure of the heart, including its chambers, valves, coverings and sulci. It also discusses the anatomy of arteries and veins, noting they each have three layers (tunica) - the tunica intima, tunica media and tunica adventitia. Arteries have a thicker tunica media layer composed of elastic fibers, while veins have a thinner wall and larger lumen. The cardiovascular system works to transport blood throughout the body to deliver nutrients and remove waste.
CVS/Anatomy of heart/ B.pharmacy 2 semester
The cardiovascular system is sometimes called the blood-vascular, or simply the circulatory system.
It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.
The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive.
The arteries carry blood away from the heart; the veins carry it back to the heart.

The cardiovascular system consists of the heart and blood vessels. The heart is a muscular organ located in the chest that pumps blood through the body in a process called circulation. It has four chambers - two atria that receive blood and two ventricles that pump blood. The heart functions throughout life to circulate oxygenated blood from the lungs and nutrients throughout the body via two types of circulation - pulmonary and systemic. The cardiac cycle describes the repeating sequence of heart contraction and relaxation that pumps blood through the circulatory system.

Unit Lesson
The Cardiovascular System
The major components of the cardiovascular system are the heart, blood, and blood vessels. The heart is an
organ that serves as a pump through the system, blood is a form of connective tissue that has a liquid
component in the form of plasma, and blood vessels serve as the series of passageways for the transport of
blood to and from the cells of the body (Colbert, Ankney, & Lee, 2013). The heart beats about 100,000 times
every day. If you do the math, you will note that this adds up to more than 35 million beats per year! The heart
is truly a fascinating organ, but it does not act alone. There are several other supportive structures and
processes that allow the heart to do its work while at rest and even in the most strenuous physical situations
imaginable.
Anatomy of the Heart
The heart is located in the thoracic cavity between the two lungs, and it rests upon the diaphragm. An
average human heart weighs approximately 300 grams and is 14 centimeters long by 9 centimeters wide
(Moini, 2013). The heart is approximately the size of a closed fist. The apex of the heart is the pointed end
that forms the tip of the left ventricle, a lower chamber of the heart. The base of the heart is on the posterior
aspect and it is formed by the atria, or the upper chambers of the heart.
The heart is surrounded by a series of protective layers that help to hold it in place. This protective layer is
known as the pericardium. The pericardium consists of two different layers: the fibrous pericardium and the
serous pericardium. The fibrous pericardium is the tougher, outer layer whereas the serous pericardium is the
thinner, more delicate inner layer. The outer layer of the parietal layer of the serous pericardium is fused to
the fibrous pericardium and the inner visceral layer of the serous pericardium (also known as t ...
Circulatory system final
Pulmonary arteries carry oxygen-poor blood from the heart to the lungs for oxygenation.
Heart
The heart is a muscular organ responsible for pumping blood through the circulatory system. It has four chambers - the left and right atria which receive blood, and the left and right ventricles which pump blood out. The heart is enclosed in a sac called the pericardium and has three layers - the outer epicardium, middle myocardium made of muscle, and inner endocardium. Blood flows through the heart in two circuits, pulmonary and systemic. The heart works nonstop to supply the body with oxygenated blood.

The heart is a hollow muscular pump located in the chest cavity. It has four chambers - two upper receiving chambers called atria and two lower pumping chambers called ventricles. The left side of the heart pumps oxygenated blood through the body while the right side pumps deoxygenated blood to the lungs. The heart is surrounded by membranes and tissues that protect and support it. It receives blood supply through the coronary arteries and pumps over 5 million liters of blood per year through a complex system of chambers, valves, nerves and muscles.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
