The pericardium is the central compartment of the thoracic cavity that contains the heart and roots of its great vessels. It is subdivided into the fibrous pericardium and visceral pericardium. The fibrous pericardium makes up the outer layer and is continuous with the parietal pericardium. The visceral pericardium forms the inner layer and covers the surface of the heart. Blood supply to the pericardium is provided by branches of the internal thoracic artery and other arteries.

Pericardium Anatomy
The pericardium is a double-walled fibroserous membrane that surrounds the heart. It has a fibrous outer layer and a serous inner layer known as the epicardium. The pericardium maintains the heart's position, acts as a barrier to infection, and lubricates the space between the layers. It contains pericardial sinuses and has attachments superiorly, inferiorly, and posteriorly in the mediastinum. The pericardium receives its blood supply from branches of the phrenic and intercostal arteries and drains into veins that empty into the azygos system. It is innervated by the phrenic nerve and vagus nerve. Card

The document discusses the anatomy of the pericardium. It describes the pericardium as having an outer fibrous layer and inner serous layer with sinuses. It details the attachments, structures that pierce it, and its blood supply from the internal thoracic artery and coronary arteries. Complications like pericarditis and pericardial effusion are mentioned.
The pericardium
The pericardium is a fibroserous sac that surrounds the heart and roots of the great vessels. It consists of the fibrous pericardium and serous pericardium. The fibrous pericardium is a conical sac made of fibrous tissue that protects the heart. The serous pericardium is a double-layered membrane that forms the pericardial sac, with fluid allowing the heart to move smoothly. The pericardium contains the heart, vessels, and parts of the great vessels, and has transverse and oblique sinuses.
Pericardium
The pericardium is a double-walled sac that surrounds the heart. It has an outer fibrous layer and inner serous layer. The serous layer forms a closed sac that contains the heart and major blood vessels. It prevents overexpansion of the heart and limits its movement while also acting as a shock absorber. Conditions like pericardial effusion and pericarditis can develop if excess fluid accumulates in the pericardial space or it becomes inflamed.
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.

ANATOMY OF BLOOD VESSELS
Tunica Interna – innermost endothelium of simple squamous epithelium + basement membrane
Arteries – have an “internal elastic lamina” of elastic CT to allow for expansion under pressure
Veins – may have “valves” (folds of endothelium + CT) to prevent backflow of blood due to low pressure Microscopic, very thin-walled vessels comprised of endothelium with basement membrane; allows for filtration and reabsorption Found in all tissues of the body except for those that are “avascular” Usually form branching networks (“capillary beds”) within tissues for increased surface area blood flow into capillaries may be regulated by “pre- capillary sphincters” may have a central or “thoroughfare” channel that provides direct connection between “metarteriole” (terminal end of arteriole) & venule
The pericardium
The pericardium is a fibroserous sac that surrounds the heart and roots of the great vessels. It has two layers - an outer fibrous layer and inner serous layer. The serous layer further divides into the parietal layer lining the fibrous sac and visceral layer adhered to the heart. Between these layers is the pericardial cavity containing fluid. The pericardium functions to support and protect the heart while allowing movement. Conditions like pericarditis or excess fluid accumulation can lead to cardiac tamponade.
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.
Mediastinum
The mediastinum is the central compartment of the thorax located between the two lungs. It is divided into superior, anterior, middle and posterior mediastinum. The mediastinum contains the heart, great vessels, trachea, esophagus and other structures. On a chest x-ray, the subdivisions of the mediastinum are visible with the cardiac shadow marking the middle mediastinum. Conditions like mediastinitis, widening of the mediastinum and mediastinal shift can occur when the mediastinum is affected.

Pericardium
Pericardium is a tough double layered membrane which covers the heart. The space between these two layers is filled with pericardial fluid which protects the heart from any kind of external jerk or shock. There are two layers to the pericardial sac: the outermost fibrous pericardium and the inner serous pericardium. The serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of the epicardium. The epicardium is the layer immediately outside of the heart muscle proper (the myocardium.The visceral layer extends to the beginning of the great vessels, becoming one with the parietal layer of the serous pericardium. This happens at two areas: where the aorta and pulmonary trunk leave the heart and where the superior vena cava, inferior vena cava and pulmonary veins enter the heart.In between the parietal and visceral pericardial layers there is a potential space called the pericardial cavity. It is normally lubricated by a film of pericardial fluid. Too much fluid in the cavity (such as in a pericardial effusion) can result in pericardial tamponade (compression of the heart within the pericardial sac). A pericardiectomy is sometimes needed in these cases
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.

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.

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.

Thorax20Chapter201120Pericardium20Newpdf.pdf
The pericardium is a fibroserous sac that encloses and protects the heart. It has two layers - an outer fibrous pericardium made of thick connective tissue, and an inner serous pericardium which is a double-layered sac. The potential space between the layers is called the pericardial cavity, which normally contains a small amount of fluid. The pericardium has sinuses that allow for the movement of blood vessels during the heart's contraction and relaxation. It serves several functions including protecting the heart and preventing excessive movement.
Pericardium and Heart
The pericardium surrounds the heart and consists of the fibrous pericardium and serous pericardium. The serous pericardium forms the parietal and visceral layers between which is the pericardial cavity. The heart is a hollow muscular organ located in the mediastinum. It has chambers, valves, arteries and nerves that allow it to pump blood efficiently to the body. The inner layers of the heart include the endocardium and myocardium separated by chambers and valves into four compartments to properly oxygenate the body.

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.
