Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
The distinguishing feature of intravascular hemolysis is the release of RBC contents into the blood stream. The metabolism and elimination of these products, largely iron-containing compounds capable of doing damage through Fenton reactions, is an important part of the condition. Several reference texts exist on the elimination pathways, for ...
Diagram showing the development of different blood cells from hematopoietic stem cells to mature cells.. A blood cell (also called a hematopoietic cell, hemocyte, or hematocyte) is a cell produced through hematopoiesis and found mainly in the blood.
The sample is lysed and dissolved into an electrolyte solution in a container, which also holds a smaller container. The smaller container has two pumps running to and from its solution, one creating a vacuum and the other replacing the lost solution. The smaller container has a small hole (an orifice) near the bottom of the container.
In the microcirculation consisting of the very small and smallest blood vessels, the capillaries, tiny thrombi (microthrombi) [5] known as microclots can obstruct the flow of blood in the capillaries. Microclots are small clumps of blood that form within the circulation, usually as a result of a larger thrombus breaking down into smaller pieces.
Over time, when red blood cells need to be replenished, the hemoglobin is broken down in the spleen; it breaks down into two parts: heme group consisting of iron and bile and protein fraction. While protein and iron are utilized to renew red blood cells, pigments that make up the red color in blood are deposited into the bile to form bilirubin ...
Carbonic anhydrase catalyzes the conversion of carbon dioxide and water into carbonic acid. This molecule breaks down into bicarbonate and hydrogen ions. This break down process occurs in red blood cells. Ultimately, the concentration of bicarbonate ions in the bloodstream affects the formation of the protein carbaminohemoglobin in the body. [11]
The Fahraeus effect occurs because the average RBC velocity is higher than the average plasma velocity. The Fåhræus effect ( / f ɑː ˈ r eɪ . ə s / ) is the decrease in average concentration of red blood cells in human blood as the diameter of the glass tube in which it is flowing decreases.
