Hydrostatic pressure within blood vessels tends to cause water to filter out into the tissue. This leads to a difference in protein concentration between blood plasma and tissue. As a result, the colloidal or oncotic pressure of the higher level of protein in the plasma tends to draw water back into the blood vessels from the tissue. Starling's ...
Elevated vascular permeability can allow excess fluid to leave blood vessels and collect in tissues resulting in edema; vasodilation prevents blood vessels from constricting to adapt to reduced volume in the vessels, causing low blood pressure and septic shock. [11] In the case of inflammation, vasodilation is caused by cytokines. [7]
It is possible for cardiogenic pulmonary edema to occur together with cardiogenic shock, in which the cardiac output is insufficient to sustain an adequate blood pressure to the lungs. This can be treated with inotropic agents or by intra-aortic balloon pump , but this is regarded as temporary treatment while the underlying cause is addressed ...
It also serves to regulate blood flow and tissue perfusion, thereby affecting blood pressure and responses to inflammation which can include edema (swelling). Most vessels of the microcirculation are lined by flattened cells of the endothelium and many of them are surrounded by contractile cells called pericytes. The endothelium provides a ...
Heat edema is a cutaneous condition characterized by dependent edema from vasodilatory pooling. [2] Heat causes the blood vessels to expand (dilate), so body fluid moves into the hands or legs by gravity. The balance of salt in the body is also a risk factor for heat edema.
Atherosclerosis is characterized by the build-up of plaque inside your blood vessels. It can lead to stenosis, which is a narrowing of your artery walls. Plaque is a fatty substance made up of:
Lymphedema, also known as lymphoedema and lymphatic edema, is a condition of localized swelling caused by a compromised lymphatic system. [2] The lymphatic system functions as a critical portion of the body's immune system and returns interstitial fluid to the bloodstream .
Cerebral edema is excess accumulation of fluid in the intracellular or extracellular spaces of the brain. [1] This typically causes impaired nerve function, increased pressure within the skull, and can eventually lead to direct compression of brain tissue and blood vessels. [1]
