A large infusion of red blood cells (and resulting increase in cellular concentration) could increase blood viscosity and bring about a decrease in cardiac output, a decrease in blood flow velocity, and a reduction in peripheral oxygen content - all of which would reduce aerobic capacity (#7). The human heart was not designed to pump this thickened blood throughout the body and, therefore, could lead to a multitude of problems.
cerebral blood flow
Advantages: longer endurance in physical activity due to more oxygenated blood being put into your blood stream... (the more oxygen in your blood the longer your muscles will work for) Disadvantages: risk of any diseases passed through blood and low blood flow leading to possible heart failure
The longer the vessel is the more friction it applies on the passing blood, the less the blood flow is.
Blood viscosity is the most important efect on blood velocity. Viscosity meaning how thin or thick the blood is. Velocity meaning the flow of blood. If the blood is too thick it's velocity will be slow. If the blood is thin, the blood will flow faster.
Serious dehydration is a form of hypovolaemic shock and would lower BP.
Blood vessel radius has a larger effect on the body because changes in radius significantly impact blood flow resistance, which affects blood pressure regulation and delivery of oxygen and nutrients to tissues. Vessel length, on the other hand, has a smaller direct effect on blood flow resistance and overall cardiovascular function.
It restricts blood flow and mobility.
The flow or blood
Excersice increases blood flow, more blood Flow to the brain = increased oxygen= increased energy = increased mental Sharpness! :)

albumin increases colloid osmotic pressure
Blood cells are a part of blood. Blood is not a part of blood cells. Blood can't flow backward and forward within blood cells. Blood cells can flow backward and forward within blood.
