MCQ Questions
Q.1.
Which of the following is not a distribution function of blood? transport of metabolic wastes from cells delivery of oxygen to body cells transport of hormones to their target organs transport of salts to maintain blood volume
  • 27%
    Erthrocytes can bend a twist to fit through vesselsErythrocytes are held in shape by flexible proteins that allow the cell to bend, twist, and cup, but that will return it to its normal shape. This facilitates the movement of erythrocytes through capillaries that are sometimes smaller than they are.

  • 13%
    polypeptide chains (globins), heme groups, and iron ions
  • 40%
    a reduced availability of oxygen Reduced oxygen delivery to the kidneys will result in the release of erythropoietin (EPO), which in turn promotes the release of more erythrocytes from the bone marrow.
