Specialty. Cardiology. Cherry angioma, also called cherry hemangioma [ 1] or Campbell de Morgan Spot, [ 2] is a small bright red dome-shaped bump on the skin. [ 3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [ 3][ 4] If scratched, they may bleed.
Blood vessels are the structures of the circulatory system that transport blood throughout the human body. [ 1] These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues. Blood vessels are needed to sustain life, because all of the body's tissues rely on ...
Vascular tumor. A vascular tumor is a tumor of vascular origin; a soft tissue growth that can be either benign or malignant, formed from blood vessels or lymph vessels. [ 1] Examples of vascular tumors include hemangiomas, lymphangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas.
Hemodynamics explains the physical laws that govern the flow of blood in the blood vessels. Blood flow ensures the transportation of nutrients, hormones, metabolic waste products, oxygen, and carbon dioxide throughout the body to maintain cell-level metabolism, the regulation of the pH, osmotic pressure and temperature of the whole body, and ...
Capillaries join the arteries and veins. The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [ 1][ 2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia ...
Atherosclerosis[ a] is a pattern of the disease arteriosclerosis, [ 8] characterized by development of abnormalities called lesions in walls of arteries. This is a chronic inflammatory disease involving many different cell types, and driven by elevated levels of cholesterol in the blood. [ 9] These lesions may lead to narrowing of the arterial ...
In cell biology, extracellular fluid ( ECF) denotes all body fluid outside the cells of any multicellular organism. Total body water in healthy adults is about 50–60% (range 45 to 75%) of total body weight; [ 1] women and the obese typically have a lower percentage than lean men. [ 2] Extracellular fluid makes up about one-third of body fluid ...
Neutrophils extravasate from blood vessels to the site of tissue injury or infection during the innate immune response. In immunology, leukocyte extravasation (also commonly known as leukocyte adhesion cascade or diapedesis – the passage of cells through the intact vessel wall) is the movement of leukocytes (white blood cells) out of the ...
