Flow cytometry (FC) is a technique used to detect and measure the physical and chemical characteristics of a population of cells or particles. [1][2][3][4] In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument. The sample is focused to ideally flow one cell at a time ...
Hemodynamics or haemodynamics are the dynamics of blood flow. The circulatory system is controlled by homeostatic mechanisms of autoregulation, just as hydraulic circuits are controlled by control systems. The hemodynamic response continuously monitors and adjusts to conditions in the body and its environment.
Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [3]
Bioinstrumentation or biomedical instrumentation is an application of biomedical engineering which focuses on development of devices and mechanics used to measure, evaluate, and treat biological systems. The goal of biomedical instrumentation focuses on the use of multiple sensors to monitor physiological characteristics of a human or animal ...
Hematology analyzers (also spelled haematology analysers in British English) are used to count and identify blood cells at high speed with accuracy. [1][2][3] During the 1950s, laboratory technicians counted each individual blood cell underneath a microscope. Tedious and inconsistent, this was replaced with the first, very basic hematology ...
Serum (blood) Preparation of serum cups for a lipids panel designed to test cholesterol levels in a patient's blood. Serum (/ ˈsɪərəm /) is the fluid and solvent component of blood which does not play a role in clotting. [1] It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors removed.
The microcirculation is the circulation of the blood in the smallest blood vessels, the microvessels of the microvasculature present within organ tissues. [1] The microvessels include terminal arterioles, metarterioles, capillaries, and venules. Arterioles carry oxygenated blood to the capillaries, and blood flows out of the capillaries through ...
Reticuloendothelial system. In anatomy the term reticuloendothelial system (abbreviated RES), often associated nowadays with the mononuclear phagocyte system (MPS), was employed by the beginning of the 20th century to denote a system of specialised cells that effectively clear colloidal vital stains (so called because they stain living cells ...
