MICROANATOMY

Detailed explanation-1: -Anemia is a reduction in hemoglobin (Hb) or hematocrit (HCT) or RBC count. It is a presentation of an underlying condition and can be subdivided into macrocytic, microcytic, or normocytic . Patients with anemia typically present with vague symptoms such as lethargy, weakness, and tiredness.

Detailed explanation-2: -What is anemia? When you don’t have enough healthy red blood cells, you have a condition called anemia. This means your blood has lower than normal hemoglobin (Hgb) levels. Hemoglobin is the part of the red blood cell (RBC) that carries oxygen to all the cells in your body.

Detailed explanation-3: -Hemoglobin is the oxygen-carrying protein inside red blood cells. It gives red blood cells their color. People with anemia do not have enough hemoglobin. The body needs certain vitamins, minerals, and nutrients to make enough red blood cells.

Detailed explanation-4: -Anemia is a decrease in the number of red blood cells (RBCs) as measured by the red cell count, the hematocrit, or the red cell hemoglobin content. In men, anemia is defined as any of the following: Hemoglobin < 14 g/dL (140 g/L)

Detailed explanation-5: -Therefore, a loss of RBC deformability at very low shear rates (less than 1 s–1) results in a decrease in blood viscosity (Chien et al., 1970). In contrast, at shear rates above 1 s–1, a decrease in RBC deformability causes blood viscosity to increase (Chien et al., 1970).
