  2. Pericardium - Wikipedia

    en.wikipedia.org/wiki/Pericardium

    The pleural cavity and the pericardial cavity are exaggerated since normally there is no space between the pleurae or between the pericardium and heart. Pericardium is also known as cardiac epidermis. Surrounds heart and bases of pulmonary artery and aorta. Deep to sternum and anterior chest wall.

  3. Pericardial fluid - Wikipedia

    en.wikipedia.org/wiki/Pericardial_fluid

    The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart. Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the ...

  4. Serous membrane - Wikipedia

    en.wikipedia.org/wiki/Serous_membrane

    A serous membrane lines the pericardial cavity of the heart, and reflects back to cover the heart, much like an under-inflated balloon would form two layers surrounding a fist. Called the pericardium, this serous membrane is a two-layered sac that surrounds the entire heart except where blood vessels emerge on the heart's superior side; [4]

  5. Pericardial effusion - Wikipedia

    en.wikipedia.org/wiki/Pericardial_effusion

    A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space) between them. [1]

  6. Potential space - Wikipedia

    en.wikipedia.org/wiki/Potential_space

    Though it only contains a small amount of fluid normally, it can sometimes accumulate fluid or air that widens the space. [2] The pericardial space is another potential space that may fill with fluid (effusion) in certain disease states (e.g. pericarditis; a large pericardial effusion may result in cardiac tamponade).

  7. Pericardiocentesis - Wikipedia

    en.wikipedia.org/wiki/Pericardiocentesis

    The pericardium is a fibrous sac surrounding the heart composed of two layers: an inner visceral pericardium and an outer parietal pericardium. [1] The area between these two layers is known as the pericardial space and normally contains 15 to 50 mL of serous fluid. [2]

  8. Anatomy of the human heart - Wikipedia

    en.wikipedia.org/wiki/Anatomy_of_the_human_heart

    The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

  9. Heart - Wikipedia

    en.wikipedia.org/wiki/Heart

    The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
