What effect will increasing the concentration of red cells in blood have? It will: A. decrease blood viscosity and increase aortic pressure B. increase blood viscosity and decrease aortic pressure C. increase blood viscosity and increase aortic pressure D. decrease blood viscosity and decrease aortic pressure
Option C.Viscosity will increase because the quantity of rbc increases. This will additionally increase the resistance to go with the drift so BP withinside the aorta will increase a bit.
