Q:

What happens if you have too many red blood cells?

A:

Quick Answer

Health Hype states that an excess amount of red blood cells affects the viscosity of blood and causes the rate of blood flow to decrease. While the body copes with a slight increase or decrease in the red blood cell concentration within the blood, too many red blood cells or too few red blood cells have a plethora of effects on the human body.

Full Answer

According to the Mayo Clinic, red blood cell production increases either to compensate for low oxygen levels due to poor heart or lung function or to compensate for lower oxygen levels at higher altitudes. Extra red blood cells are also produced when the kidneys release too much of a protein that promotes red blood cell growth. The primary function of red blood cells is to carry oxygen in the bloodstream from the lungs to the cells of the body. The presence of red blood cells in human blood has many different effects on the body and influences the action and function of other parts of the cardiovascular system. Red blood cells contain hemoglobin, a protein that carries 97 percent of the oxygen in the body. The other 3 percent of the body's oxygen is dissolved in the plasma.

  • Q:

    What does "low white blood cells" mean?

    A:

    Low white blood cell counts may occur when patients have conditions that interfere with bone marrow functioning or conditions like cancer, viral infections and autoimmune disorders, according to Mayo Clinic. Severe infections may also cause the body to use more white blood cells than it can produce.

  • Q:

    What happens to red blood cells when they are placed in distilled water?

    A:

    When red blood cells are placed in distilled water, which is hypotonic compared to the solution contained within the cells' membranes, the distilled water will diffuse into the red blood cells and cause them to burst. Placing red blood cells in any solution which contains a lesser degree of solute than that of the solution within the cells will cause water to diffuse into them. Because distilled water contains a zero concentration of solute, it will predictably diffuse into a red blood cell in an attempt to equalize the osmotic pressure on both sides of the cell membrane.

    What happens to red blood cells in an isotonic solution?

    A:

    Red blood cells maintain normal morphology and chemical exchange rates in isotonic solutions. A cell is in an isotonic solution if the osmotic pressure inside the cell is equivalent to the osmotic pressure of the solution surrounding the cell. Plasma is the primary isotonic solution for red blood cells.
