Blood plasma is a light amber -colored liquid component of blood in which blood cells are absent, but which contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. [1] It is the intravascular part of extracellular fluid (all body fluid outside cells).
Exsanguination is losing enough blood to cause death. A person does not have to lose all of their blood to exsanguinate. People can die from losing half to two-thirds of their blood. [1] The average adult has about 4 to 6 liters of blood (9 to 12 US pints) in their body. The average man has more blood than the average woman, and people who ...
Hypovolemic shock. Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1] [2] It could be the result of severe dehydration through a variety of mechanisms or blood loss. [3] [2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow ...
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [1] This may be due to either a loss of both salt and water or a decrease in blood volume. [2] [3] Hypovolemia refers to the loss of extracellular fluid and should not be confused with dehydration.
Hemorrhagic shock, hypovolemic shock, exsanguination. Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding ...
6947. Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state, hemoglobin, which contains iron, cannot be formed. [5] Plummer–Vinson syndrome.
Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon. Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer ).
