Human Heart and its function
The circulatory system is made up of the heart and blood vessels. The heart is a muscular organ about the size of a fist located slightly left of the breastbone. It pumps blood through blood vessels including arteries, veins, and capillaries. The heart has four chambers - two upper chambers called atria that receive blood and two lower chambers called ventricles that pump blood out of the heart. It contracts in a cardiac cycle where the atria and ventricles contract simultaneously to circulate blood throughout the body.
Heart Structure and Function
The document describes the structure and function of the heart. It explains that deoxygenated blood enters the right atrium via the vena cava and is then pumped to the right ventricle. The right ventricle pumps the blood to the lungs through the pulmonary artery. Oxygenated blood returns from the lungs to the left atrium via the pulmonary veins. The left atrium then pumps the blood to the left ventricle, which pumps it out to the body through the aorta. Valves prevent backflow of blood throughout the heart.
THE HEART PPT
The heart is located slightly left of center in the chest and is about the size of a fist. It pumps blood through arteries and veins called blood vessels throughout the body. The blood carries oxygen, nutrients, and chemicals to tissues and removes waste. Coronary heart disease, cardiovascular disease, and heart failure can occur if the heart does not circulate blood properly. Maintaining a healthy lifestyle through diet and exercise can help prevent heart disease.
Parts of the Heart and Their functions
This document describes the main parts of the heart and their functions. It discusses how the superior vena cava and inferior vena cava deliver deoxygenated blood to the right atrium. It then explains that the right ventricle pumps deoxygenated blood to the lungs via the pulmonary artery and the left ventricle pumps oxygenated blood from the lungs to the body through the aorta. The document also mentions the roles of the valves in regulating blood flow through the heart chambers.

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.
The Human Blood
This presentation is part of the Grade 6 lesson in circulatory system.This tackles the function of the human blood, its solid components and specific contents under them, and the four blood types.

Johny's A&P Structure and Function of Heart
The document provides information about the anatomy and physiology of the heart. It discusses the following key points in 3 sentences:
The heart is a muscular organ located in the mediastinum that pumps blood through the circulatory system via four chambers - two upper atria and two lower ventricles. It has three layers - epicardium, myocardium and endocardium - and is surrounded by the pericardium. The heart has a conduction system including the sinoatrial node which acts as the pacemaker, generating electrical impulses that cause coordinated contractions of the atria and ventricles to efficiently circulate blood.
structure of heart
The document summarizes the structure and function of the human heart. It describes the heart as a muscular pump divided into four chambers - the right and left atria which receive blood, and the right and left ventricles which pump blood out. It details the circulation of blood through the pulmonary and systemic circuits, and explains the roles and structures of the heart valves in ensuring one-way blood flow. It also outlines the layers that surround and protect the heart.
The heart structure
The document provides instructions for creating an educational booklet outlining the structure and function of the major body systems for trainee nurses. It lists the 11 body systems that should be covered in the booklet: cardiovascular, respiratory, digestive, renal, nervous, endocrine, musculo-skeletal, immune, lymphatic, and male and female reproductive systems. For each system, the booklet should describe its gross structure and how its structure relates to its function.
Conduction system of heart
This document provides an overview of the conduction system of the heart. It begins with the development of the primitive cardiac tube and differentiation of heart structures. It then describes the specialized conduction tissues including the sinoatrial node, atrioventricular node, bundle of His, bundle branches, and Purkinje fibers. It discusses impulse conduction through the heart and characteristics of cardiac conduction cells. Finally, it covers conduction defects, implications for congenital heart anomalies like ASD and VSD, and considerations for cardiac surgery.
Blood supply of heart (1)
The document describes the blood supply and conduction system of the heart. It discusses the right and left coronary arteries, which are the main arteries that supply blood to the heart. It details the branches and territories supplied by each artery. It also describes the conduction system of the heart, including the sinoatrial node, atrioventricular node, bundle of His, and Purkinje fibers. It provides an overview of how electrical impulses are conducted through the heart to trigger contractions.
Blood & its functions
The human body contains approximately 5 liters of blood composed of plasma and cellular elements. Plasma is 55% of blood and contains water, proteins, electrolytes, and other substances. Cellular elements include red blood cells containing hemoglobin, white blood cells for immunity, and platelets for clotting. Blood transports oxygen, nutrients, wastes, hormones, and more throughout the body.
Conduction System of the Heart
The conduction system of the heart is initiated by the sinoatrial node, which acts as the dominant pacemaker. It is located in the junction of the right atrium and superior vena cava and is innervated by the parasympathetic and sympathetic nervous systems. Conduction then proceeds through the atrioventricular node, which slows conduction to allow for ventricular filling, and the bundle of His divides into left and right bundle branches to stimulate the ventricles.
Heart Anatomy
The heart is a hollow muscular organ located in the thorax between the lungs. It has 4 chambers - 2 atria that receive blood and 2 ventricles that pump blood out of the heart. The right side receives deoxygenated blood from the body and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it out to the body. The heart is surrounded by a membrane called the pericardium which restricts its movement and acts as a lubricated sac. It has 4 valves that ensure one-way blood flow through the heart chambers. The heart is supplied by the left and right coronary arteries and its venous drainage occurs through the coronary sinus into the right atrium.

Heart
The document describes the anatomy and structures of the heart. It discusses:
- The heart is surrounded by the pericardium, a double-walled sac that has an outer fibrous layer and inner serous layers separated by fluid.
- The heart has four chambers - two upper atria that receive blood and two lower ventricles that pump blood out. Blood flows through valves between the chambers.
- The heart wall has three layers - the outer epicardium, middle muscular myocardium, and inner endothelial endocardium.
- The heart is supplied by the right and left coronary arteries and drains into the coronary sinus vein.
- Nerves from the autonomic nervous system
The Human Heart
The document summarizes the structure and function of the human heart. It describes how blood flows through the heart in one direction via the cardiac cycle. The heart acts as a double pump, with the right side collecting deoxygenated blood and pumping it to the lungs, and the left side collecting oxygenated blood and pumping it to the body. Key parts of the heart are identified including the four chambers and valves that ensure one-way blood flow. Several common heart diseases and treatment options are also outlined.
Procedures
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise boosts blood flow, releases endorphins, and promotes changes in the brain which help enhance one's emotional well-being and mental clarity.
Heart disease
Arterial aging progresses through distinct stages that can lead to heart attack. While the first symptom of a heart attack can be sudden death, men and women face equal risk by ages 60-70. In 50% of cases, blood pressure and cholesterol levels are normal, and children of parents with premature heart disease have a much higher (200-300%) risk themselves.
Circulatory system( science)
The circulatory system transports oxygen, nutrients, hormones, and waste throughout the body. It consists of the heart, blood vessels, and blood. The heart pumps blood through the vessels in two circuits - the pulmonary circuit transports blood to the lungs to receive oxygen and the systemic circuit transports oxygenated blood to the entire body. The circulatory system allows for the exchange of materials between blood and tissues to sustain life.
Circ.sys.
The circulatory system includes the blood, blood vessels, and heart. The blood transports nutrients, gases, hormones, and wastes throughout the body. It also helps fight infections and regulates temperature and pH levels. The circulatory system has several cell and tissue types that perform specialized functions like carrying oxygen (red blood cells), fighting infections (white blood cells), and promoting clotting (platelets). Many disorders can affect the circulatory system if these cells are damaged or numbers become abnormal. Modern advances help treat issues like blood transfusions, viral diseases, and organ transplant compatibility.
1st science 12 describes the function of each respiratory organ
The document describes the parts and functions of the respiratory system. It discusses the upper respiratory tract including the nose, mouth and throat and their functions of warming, filtering and moistening air. It then discusses the lower respiratory tract including the lungs, bronchi, trachea and their functions of gas exchange and transporting air. It also describes how the ribs, rib cage and diaphragm protect the lungs and how the lungs are made up of bronchi, bronchioles and alveoli where gas exchange occurs through capillaries.
Control of cardiac cycle
The document discusses the roles of the sinoatrial node, atrioventricular node, and Purkyne tissue in controlling the cardiac cycle. The sinoatrial node initiates electrical impulses that cause atrial contraction. The impulses then travel to the atrioventricular node and down the Purkyne tissue in the ventricles to trigger ventricular contraction. This coordinated process allows for the synchronized pumping of blood through the heart.
Blood Flow Through The Heart
The document provides information about blood flow through the heart, including mnemonics to remember the order of valves and structures that blood enters and exits. It also includes games to test knowledge about the heart chambers, direction of blood flow, and specific valves and structures involved in oxygenated and deoxygenated blood flow.
Full Face Transplant
This document discusses the possibility and ethics of performing a full face transplant. It presents the case study of Ms. Poonam Singhal, who suffered severe facial disfigurement from an acid attack. The document outlines the medical feasibility of a full face transplant using modern techniques like microsurgery, immunosuppressants, and tissue matching. It also considers ethical issues like finding an appropriate donor and managing post-operative care. Hypothetical imaging is presented to illustrate what Ms. Singhal's face could look like after a successful full face transplant. The debate on this procedure is just beginning.

How to consult a patient
This document provides guidance on properly consulting with patients considering cosmetic surgery. It outlines important steps like determining the patient's motivation, assessing their emotional state, examining relevant areas, and recommending the right procedure or surgeon. The key aspects are choosing a qualified surgeon, making sure the timing is appropriate, matching expectations with limitations, and committing only to what can realistically be delivered to achieve the best outcome.
Future of Cosmetic Surgery
This document discusses the future of cosmetic surgery in India according to Dr. Vijay Sharma. It notes that India has become a major medical tourism destination, and cosmetic surgery in particular is flourishing due to availability of qualified surgeons, high-quality implants and equipment, advanced technology, and continual medical education. Some key factors driving the growth of cosmetic surgery in India include changes in lifestyle, increased awareness, professional needs, important life events, self-image concerns, and globalization. The number of cosmetic surgeries performed in India has increased over 600-fold from 1987 to 2004. Common procedures include rhinoplasty, breast augmentation, and liposuction.
Excellent Makeover Program
Dr. Vijay Sharma outlines 11 "Golden Rules of Beauty" based on facial features and proportions that are considered universally attractive. These include having an oval face, equal length of face above and below the nose, high cheekbones, convex rather than concave facial features, and balanced proportions between parts of the face and body. He argues that modern society puts immense pressure on individuals to conform to narrow beauty standards due to emphasis on youth, beauty, and success. This "hyperaesthetic tension" has led to an increase in cosmetic procedures and taken importance away from inner virtues. Societal tolerance for those not considered attractive has decreased significantly.
Breast augmentation
The document discusses breast augmentation, including indications for the procedure, surgical approaches, implant placement and types, the operative procedure, postoperative care, and potential complications. Breast augmentation involves surgically increasing breast size through the use of saline- or silicone-filled breast implants inserted through incisions around the nipple, under the arm, or in the breast crease. Postoperative recovery takes several weeks, with limited activity and follow up visits with the surgeon to monitor healing.
Best face forward
The document discusses the rise in popularity of cosmetic surgery in India from 1987 to 2004. It attributes this 600-fold increase to several key factors, including increased awareness, emphasis on youth and beauty in modern Indian culture, globalization, and the need for professional presentation. Cosmetic surgery is now more widely available and affordable in India compared to other countries. The document also provides before and after photos of common cosmetic procedures like nose jobs, breast augmentations, and fat removal treatments.
Role of computer simulation
This document discusses the role of advanced computer simulation in modern cosmetic surgery. It describes how computer simulation can help both physicians and patients by allowing patients to visually express their desired changes and allowing doctors to demonstrate expected results. The objectives of computer simulation are to avoid patient dissatisfaction by explaining realistic expectations and limitations prior to surgery. A survey of over 7,000 patients found that explaining both desired results and potential problems led to higher patient satisfaction compared to only explaining benefits. The conclusion is that educating patients thoroughly through computer simulation can increase satisfaction by managing expectations.

2. It notes how every body part can be subjected to various beauty treatments and procedures by industries and professionals focused on aesthetics and appearance enhancement.
3. The medical field has also contributed to this focus on beauty, with specialties like cosmetic surgery emerging to modify and "beautify" various aspects of the body.
Hazards of hair_weaving
Hair weaving can cause several health issues including allergies, eczema, errythema, seborrhea, dermatitis, headaches, dizziness, and migraines. The document lists potential skin conditions such as eczema and dermatitis as well as neurological symptoms including headaches, dizziness, and migraines as hazards of hair weaving.
Complications of textured_surface_implants
Silicone breast implants are generally considered biologically inert. However, some patients develop seromas following implantation. This document discusses several hypothesized pathophysiological pathways by which textured silicone breast implants could potentially cause generalized symptoms, but finds each of them implausible based on the scientific evidence. Specifically, silicone is unlikely to act as an antigen, adjuvant, or hapten due to its small size and inability to repeatedly bind to host molecules. A foreign body reaction and resultant cytokine production also would not be expected to cause systemic disease. The document concludes it is very unlikely that silicone breast implants can induce generalized symptoms or disease.
Human fat tissue bank
Dr. Vijay Sharma proposes the concept of a Human Fat Tissue Bank that would collect, store, and preserve human fat cells through liposuction in order to later reintroduce the fat through autologous fat grafting or transplantation. The fat would be collected aseptically, stored at hypothermic temperatures, and later grafted back into the same patient or potentially another human to fill wrinkles or defects. Initial observations of autologous fat grafting show the fat can remain integrated for 12-24 months with less scarring than other dermal fillers. The Human Fat Tissue Banking concept could allow for autologous, homologous, or even heterologous fat grafting between humans and
Growth of cosmetic_surgery
The document discusses the growth of cosmetic surgery in India from 1987 to 2006. It notes that the first cosmetic surgery center in India was founded in 1987 in Bombay by Dr. Vijay Sharma. Since then, cosmetic surgeries in India have increased over 600-fold. Common procedures include rhinoplasty, breast augmentation, and liposuction. The document attributes the rise in cosmetic procedures to factors like increased awareness, lifestyle changes, globalization, and the success of Indian beauty pageant contestants.
Full face transplant
This document discusses the debate around full face transplantation. It presents the story of Poonam Singhal, who suffered severe facial disfigurement from an acid attack. The document considers whether full face transplantation is now technically and ethically feasible, given advances in areas like microsurgery, immunosuppressive drugs, and computer imaging. It outlines some of the medical, legal, and ethical issues to consider, such as donor selection and consent, ensuring transplants are only done on appropriate recipients like severe burn victims, and amending laws around acid attacks. Hypothetical before and after computer images are presented of what a full face transplant for Poonam Singhal may look like.
Duties and rights_of_cosmetic_surgeon
Dr. Vijay Sharma outlines the key duties and rights of cosmetic surgeons. Some of the main duties include rendering services to improve patients' emotional well-being and confidence rather than just for financial gain. Cosmetic surgeons must obtain proper informed consent, maintain patient privacy and confidentiality, and make treatment recommendations based on scientific evidence. They should not solicit patients directly or use publicity for commercial purposes. Cosmetic surgeons also have a duty to continue their education, treat all patients respectfully regardless of attributes, and observe relevant laws and ethical standards in their practice.
Complications of silicon implant
This document discusses common postoperative complications that can occur with silicon implants, specifically for the nose, cheeks, chin, and breasts. Some frequent complications include edema, redness, infections, abnormal pigmentation, transparent reflection of the implant, displacement of the implant, and rejection. Based on a study of 179 nose implants, 58 chin implants, 27 cheek implants, and 253 breast augmentations, the most common issues were edema, residual edema, redness, abnormal pigmentation, transparent reflection, infection, dissatisfaction leading to removal, and displacement of the implant. A unique complication of breast implants is capsule formation, requiring manual breaking for the first postoperative year. Rejection of implants is rare.
Chemical peeling
1) The document compares the use of phenol-based chemical peels with and without the addition of crotamiton oil on 127 patients. Phenol peels remove the epidermis and upper dermis, resulting in a smoother appearance after new skin growth.

Learning objectives:
1. Define an electrocardiogram (ECG) and electrocardiography
2. Describe how dipoles generated by the heart produce the waveforms of the ECG
3. Describe the components of a normal electrocardiogram of a typical bipolar lead (limb II)
4. Differentiate between intervals and segments
5. Enlist some common indications for obtaining an ECG
6. Describe the flow of current around the heart during the cardiac cycle
7. Discuss the placement and polarity of the leads of electrocardiograph
8. Describe the normal electrocardiograms recorded from the limb leads and explain the physiological basis of the different records that are obtained
9. Define mean electrical vector (axis) of the heart and give the normal range
10. Define the mean QRS vector
11. Describe the axes of leads (hexagonal reference system)
12. Comprehend the vectorial analysis of the normal ECG
13. Determine the mean electrical axis of the ventricular QRS and appreciate the mean axis deviation

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
