Explain the relationship between rbc count, ht, and viscosity.

The RBC (red blood cells) count can be defined as the total number of red blood cells present in individual blood sample.

Hematocrit ( Ht) is defined as the blood test that measures the volume percentage of red blood cells in blood.

Blood viscosity  is defined as the viscosity or flowing property of blood.

RBC (red blood cells) count , hematocrit ( Ht), and blood viscosity are related to each other that can be explained as higher percentage of red blood cells (RBCs) results in thicker blood ( blood viscosity), hematocrit reflects the number of red blood cells , If the size or number of the RBCs decreases, so will the hematocrit and vice versa.
